Blade Runner is a 1982 science fiction film directed by Ridley Scott, and written by Hampton Fancher and David Peoples. Starring Harrison Ford, Rutger Hauer and Sean Young, it is loosely based on Philip K. Dick's novel Do Androids Dream of Electric Sheep? (1968). The film is set in a dystopian future Los Angeles of 2019, in which synthetic humans known as replicants are bio-engineered by the powerful Tyrell Corporation to work on off-world colonies. When a fugitive group of Nexus-6 replicants led by Roy Batty (Hauer) escapes back to Earth, burnt-out cop Rick Deckard (Ford) reluctantly agrees to hunt them down.

Blade Runner initially underperformed in North American theaters and polarized critics; some praised its thematic complexity and visuals, while others were displeased with its slow pacing and lack of action. It later became an acclaimed cult film regarded as one of the all-time best science fiction films. Hailed for its production design depicting a "retrofitted" future, Blade Runner is a leading example of neo-noir cinema. The soundtrack, composed by Vangelis, was nominated in 1982 for a BAFTA and a Golden Globe as best original score.

The film has influenced many science fiction films, video games, anime, and television series. It brought the work of Philip K. Dick to the attention of Hollywood, and several later big-budget films were based on his work. In the year after its release, Blade Runner won the Hugo Award for Best Dramatic Presentation, and in 1993 it was selected for preservation in the U. S. National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". A sequel, Blade Runner 2049, was released in October 2017.

Seven versions of Blade Runner exist as a result of controversial changes requested by studio executives. A director's cut was released in 1992 after a strong response to test screenings of a workprint. This, in conjunction with the film's popularity as a video rental, made it one of the earliest movies to be released on DVD. In 2007, Warner Bros. released The Final Cut, a 25th-anniversary digitally remastered version; the only version over which Scott retained artistic control.

In 2019 Los Angeles, former police officer Rick Deckard is detained by officer Gaff, and brought to his former supervisor, Bryant. Deckard, whose job as a "blade runner" was to track down bioengineered beings known as replicants and "retire" (kill) them, is informed that four are on Earth illegally. Deckard starts to leave, but Bryant ambiguously threatens him, and he stays. The two watch a video of a blade runner named Holden administering the "Voight-Kampff" test, which is designed to distinguish replicants from humans based on their emotional response to questions. The test subject, Leon, shoots Holden on the second question. Bryant wants Deckard to retire Leon and the other three Tyrell Corporation Nexus-6 replicants: Roy Batty, Zhora, and Pris.

Bryant has Deckard meet with Eldon Tyrell so he can administer the test on a Nexus-6 to see if it works. Tyrell expresses his interest in seeing the test fail first and asks him to administer it on his assistant Rachael. After a much longer than standard test, Deckard concludes that Rachael is a replicant who believes she is human. Tyrell explains that she is an experiment who has been given false memories to provide an emotional "cushion".

Searching Leon's hotel room, Deckard finds photos and a synthetic snake scale. Roy and Leon investigate a replicant eye-manufacturing laboratory and learn of J. F. Sebastian, a gifted genetic designer who works closely with Tyrell. Deckard returns to his apartment where Rachael is waiting. She tries to prove her humanity by showing him a family photo, but after Deckard reveals that her memories are implants from Tyrell's niece, she leaves in tears. Meanwhile, Pris locates Sebastian and manipulates him to gain his trust.

A photograph from Leon's apartment and the snake scale lead Deckard to a strip club, where Zhora works. After a confrontation and chase, Deckard kills Zhora. Bryant orders him also to retire Rachael, who has disappeared from the Tyrell Corporation. After Deckard spots Rachael in a crowd, he is attacked by Leon, who knocks Deckard's pistol out of his hand, and attempts to kill Deckard, but Rachael uses Deckard's pistol to kill Leon. They return to Deckard's apartment, and, during an intimate discussion, he promises not to track her down; as she abruptly tries to leave, Deckard restrains her, making her kiss him.

Arriving at Sebastian's apartment, Roy tells Pris that the others are dead. Sympathetic to their plight, Sebastian reveals that because of "Methuselah Syndrome", a genetic premature aging disorder, his life will also be cut short. Sebastian and Roy gain entrance into Tyrell's secure penthouse, where Roy demands more life from his maker. Tyrell tells him that it is impossible. Roy confesses that he has done "questionable things", but Tyrell dismisses this, praising Roy's advanced design and accomplishments in his short life. Roy kisses Tyrell, then kills him. Sebastian runs for the elevator, followed by Roy, who rides the elevator down alone.^[1] Deckard is later told by Bryant that Sebastian was found dead.

At Sebastian's apartment, Deckard is ambushed by Pris, but he kills her as Roy returns. Roy's body begins to fail as the end of his lifespan nears. He chases Deckard through the building, ending on the roof. Deckard tries to jump to an adjacent roof, but is left hanging between buildings. Roy makes the jump with ease, and as Deckard's grip loosens, Roy hoists him onto the roof, saving him. Before Roy dies, he delivers a monolog about how his memories "will be lost in time, like tears in rain". Gaff arrives and shouts to Deckard about Rachael: "It's too bad she won't live, but then again, who does?" Deckard returns to his apartment and finds Rachael asleep in his bed. As they leave, Deckard notices an origami unicorn on the floor, a calling card that recalls for him Gaff's earlier statement. Deckard and Rachael leave the apartment block.

The film operates on multiple dramatic and narrative levels. It employs some of the conventions of film noir, among them the character of a femme fatale; narration by the protagonist (in the original release); chiaroscuro cinematography; and giving the hero a questionable moral outlook – extended to include reflections upon the nature of his own humanity.^[11][12] It is a literate science fiction film, thematically enfolding the philosophy of religion and moral implications of human mastery of genetic engineering in the context of classical Greek drama and hubris.^[13] It also draws on Biblical images, such as Noah's flood,^[14] and literary sources, such as Frankenstein.^[15] Although Scott said any similarity was merely coincidental,^[16] fans claimed that the chess game between Sebastian and Tyrell was based on the famous Immortal Game of 1851.^[17]

Blade Runner delves into the effects of technology on the environment and society by reaching to the past, using literature, religious symbolism, classical dramatic themes, and film noir techniques. This tension between past, present, and future is represented in the "retrofitted" future depicted in the film, one which is high-tech and gleaming in places but decayed and outdated elsewhere. In an interview with The Observer in 2002, director Ridley Scott described the film as "extremely dark, both literally and metaphorically, with an oddly masochistic feel". He also said that he "liked the idea of exploring pain" in the wake of his brother's death: "When he was ill, I used to go and visit him in London, and that was really traumatic for me."^[18]

A sense of foreboding and paranoia pervades the world of the film: corporate power looms large; the police seem omnipresent; vehicle and warning lights probe into buildings; and the consequences of huge biomedical power over the individual are explored – especially regarding replicants' implanted memories. Control over the environment is exercised on a vast scale, and goes hand in hand with the absence of any natural life; for example, artificial animals stand in for their extinct predecessors. This oppressive backdrop explains the frequently referenced migration of humans to "off-world" (extraterrestrial) colonies.^[19] Eyes are a recurring motif, as are manipulated images, calling into question the nature of reality and our ability to accurately perceive and remember it.^[20][21]

These thematic elements provide an atmosphere of uncertainty for Blade Runner's central theme of examining humanity. In order to discover replicants, an empathy test is used, with a number of its questions focused on the treatment of animals – seemingly an essential indicator of one's "humanity". The replicants appear to show compassion and concern for one another and are juxtaposed against human characters who lack empathy, while the mass of humanity on the streets is cold and impersonal. The film goes so far as to question if Deckard might be a replicant, in the process asking the audience to re-evaluate what it means to be human.^[22]

The question of whether Deckard is intended to be a human or a replicant has been an ongoing controversy since the film's release.^[23][24] Both Michael Deeley and Harrison Ford wanted Deckard to be human, while Hampton Fancher preferred ambiguity.^[25] Ridley Scott has stated that in his vision, Deckard is a replicant.^[26][27] Deckard's unicorn-dream sequence, inserted into Scott's Director's Cut and concomitant with Gaff's parting gift of an origami unicorn, is seen by many as showing that Deckard is a replicant – because Gaff could have retrieved Deckard's implanted memories.^[15][28][29] The interpretation that Deckard is a replicant is challenged by others who believe the unicorn imagery shows that the characters, whether human or replicant, share the same dreams and recognize their affinity,^[30] or that the absence of a decisive answer is crucial to the film's main theme.^[31] The film's inherent ambiguity and uncertainty, as well as its textual richness, have permitted multiple interpretations.^[32]

Casting the film proved troublesome, particularly for the lead role of Deckard. Screenwriter Hampton Fancher envisioned Robert Mitchum as Deckard and wrote the character's dialogue with Mitchum in mind.^[33] Director Ridley Scott and the film's producers spent months meeting and discussing the role with Dustin Hoffman, who eventually departed over differences in vision.^[33] Harrison Ford was ultimately chosen for several reasons, including his performance in the Star Wars films, Ford's interest in the Blade Runner story, and discussions with Steven Spielberg who was finishing Raiders of the Lost Ark at the time and strongly praised Ford's work in the film.^[33] Following his success in films like Star Wars (1977) and Raiders of the Lost Ark (1981), Ford was looking for a role with dramatic depth.^[34] According to production documents, several actors were considered for the role, including Gene Hackman, Sean Connery, Jack Nicholson, Paul Newman, Clint Eastwood, Tommy Lee Jones, Arnold Schwarzenegger, Al Pacino and Burt Reynolds.^[33]

One role that was not difficult to cast was Rutger Hauer as Roy Batty,^[35] the violent yet thoughtful leader of the replicants.^[36] Scott cast Hauer without having met him, based solely on Hauer's performances in Paul Verhoeven's movies Scott had seen (Katie Tippel, Soldier of Orange, and Turkish Delight).^[33] Hauer's portrayal of Batty was regarded by Philip K. Dick as "the perfect Batty – cold, Aryan, flawless".^[37] Of the many films Hauer made, Blade Runner was his favorite. As he explained in a live chat in 2001, "Blade Runner needs no explanation. It just [is]. All of the best. There is nothing like it. To be part of a real masterpiece which changed the world's thinking. It's awesome."^[38] Hauer rewrote his character's "tears in rain" speech himself and presented the words to Scott on set prior to filming.

Blade Runner used a number of then-lesser-known actors: Sean Young portrays Rachael, an experimental replicant implanted with the memories of Tyrell's niece, causing her to believe she is human;^[39] Nina Axelrod auditioned for the role.^[33] Daryl Hannah portrays Pris, a "basic pleasure model" replicant; Stacey Nelkin auditioned for the role, but was given another part in the film, which was ultimately cut before filming.^[33] Casting Pris and Rachael was challenging, requiring several screen tests with Morgan Paull playing the role of Deckard. Paull was cast as Deckard's fellow bounty hunter Holden based on his performances in the tests.^[33] Brion James portrays Leon Kowalski, a combat and laborer replicant, and Joanna Cassidy portrays Zhora, an assassin replicant.

Edward James Olmos portrays Gaff. Olmos drew on diverse ethnic sources to help create the fictional "Cityspeak" language his character uses in the film.^[40] His initial address to Deckard at the noodle bar is partly in Hungarian and means, "Horse dick [bullshit]! No way. You are the Blade ... Blade Runner."^[40] M. Emmet Walsh plays Captain Bryant, a hard-drinking, sleazy, and underhanded police veteran typical of the film noir genre. Joe Turkel portrays Dr. Eldon Tyrell, a corporate mogul who built an empire on genetically manipulated humanoid slaves. William Sanderson was cast as J. F. Sebastian, a quiet and lonely genius who provides a compassionate yet compliant portrait of humanity. J. F. sympathizes with the replicants, whom he sees as companions,^[41] and he shares their shorter lifespan due to his rapid aging disease.^[42] Joe Pantoliano had earlier been considered for the role.^[43] James Hong portrays Hannibal Chew, an elderly geneticist specializing in synthetic eyes, and Hy Pyke portrayed the sleazy bar owner Taffey Lewis – in a single take, something almost unheard-of with Scott, whose drive for perfection resulted at times in double-digit takes.^[44]

Interest in adapting Philip K. Dick's novel Do Androids Dream of Electric Sheep? developed shortly after its 1968 publication. Director Martin Scorsese was interested in filming the novel, but never optioned it.^[45] Producer Herb Jaffe optioned it in the early 1970s, but Dick was unimpressed with the screenplay written by Herb's son Robert: "Jaffe's screenplay was so terribly done ... Robert flew down to Santa Ana to speak with me about the project. And the first thing I said to him when he got off the plane was, 'Shall I beat you up here at the airport, or shall I beat you up back at my apartment?'"^[46]

The screenplay by Hampton Fancher was optioned in 1977.^[47] Producer Michael Deeley became interested in Fancher's draft and convinced director Ridley Scott to film it. Scott had previously declined the project, but after leaving the slow production of Dune, wanted a faster-paced project to take his mind off his older brother's recent death.^[48] He joined the project on February 21, 1980, and managed to push up the promised Filmways financing from US$13 million to $15 million. Fancher's script focused more on environmental issues and less on issues of humanity and religion, which are prominent in the novel and Scott wanted changes. Fancher found a cinema treatment by William S. Burroughs for Alan E. Nourse's novel The Bladerunner (1974), titled Blade Runner (a movie).^[2] Scott liked the name, so Deeley obtained the rights to the titles.^[49] Eventually he hired David Peoples to rewrite the script and Fancher left the job over the issue on December 21, 1980, although he later returned to contribute additional rewrites.^[50]

Having invested over $2.5 million in pre-production,^[51] as the date of commencement of principal photography neared, Filmways withdrew financial backing. In ten days Deeley had secured $21.5 million in financing through a three-way deal between The Ladd Company (through Warner Bros.), the Hong Kong-based producer Sir Run Run Shaw and Tandem Productions.^[52]

Dick became concerned that no one had informed him about the film's production, which added to his distrust of Hollywood.^[53] After Dick criticized an early version of Fancher's script in an article written for the Los Angeles Select TV Guide, the studio sent Dick the Peoples rewrite.^[54] Although Dick died shortly before the film's release, he was pleased with the rewritten script and with a 20-minute special effects test reel that was screened for him when he was invited to the studio. Despite his well-known skepticism of Hollywood in principle, Dick enthused to Scott that the world created for the film looked exactly as he had imagined it.^[37] He said, "I saw a segment of Douglas Trumbull's special effects for Blade Runner on the KNBC-TV news. I recognized it immediately. It was my own interior world. They caught it perfectly." He also approved of the film's script, saying, "After I finished reading the screenplay, I got the novel out and looked through it. The two reinforce each other, so that someone who started with the novel would enjoy the movie and someone who started with the movie would enjoy the novel."^[55] The motion picture was dedicated to Dick.^[56] Principal photography of Blade Runner began on March 9, 1981, and ended four months later.^[57]

In 1992, Ford revealed, "Blade Runner is not one of my favorite films. I tangled with Ridley."^[58] Apart from friction with the director, Ford also disliked the voiceovers: "When we started shooting it had been tacitly agreed that the version of the film that we had agreed upon was the version without voiceover narration. It was a f**king [sic] nightmare. I thought that the film had worked without the narration. But now I was stuck re-creating that narration. And I was obliged to do the voiceovers for people that did not represent the director's interests."^[34] "I went kicking and screaming to the studio to record it."^[59] The narration monologs were written by an uncredited Roland Kibbee.^[60]

In 2006, Scott was asked "Who's the biggest pain in the arse you've ever worked with?", he replied: "It's got to be Harrison ... he'll forgive me because now I get on with him. Now he's become charming. But he knows a lot, that's the problem. When we worked together it was my first film up and I was the new kid on the block. But we made a good movie."^[61] Ford said of Scott in 2000: "I admire his work. We had a bad patch there, and I'm over it."^[62] In 2006 Ford reflected on the production of the film saying: "What I remember more than anything else when I see Blade Runner is not the 50 nights of shooting in the rain, but the voiceover ... I was still obliged to work for these clowns that came in writing one bad voiceover after another."^[63] Ridley Scott confirmed in the summer 2007 issue of Total Film that Harrison Ford contributed to the Blade Runner Special Edition DVD, and had already recorded his interviews. "Harrison's fully on board", said Scott.^[64]

The Bradbury Building in downtown Los Angeles served as a filming location, and a Warner Bros. backlot housed the 2019 Los Angeles street sets. Other locations included the Ennis-Brown House and the 2nd Street Tunnel. Test screenings resulted in several changes, including adding a voice-over, a happy ending, and the removal of a Holden hospital scene. The relationship between the filmmakers and the investors was difficult, which culminated in Deeley and Scott being fired but still working on the film.^[65] Crew members created T-shirts during filming saying, "Yes Guv'nor, My Ass" that mocked Scott's unfavorable comparison of U.S. and British crews; Scott responded with a T-shirt of his own, "Xenophobia Sucks" making the incident known as the T-shirt war.^[66][67]

Ridley Scott credits Edward Hopper's painting Nighthawks and the French science fiction comics magazine Métal Hurlant, to which the artist Jean "Moebius" Giraud contributed, as stylistic mood sources.^[68] He also drew on the landscape of "Hong Kong on a very bad day"^[69] and the industrial landscape of his one-time home in northeast England.^[70] The visual style of the movie is influenced by the work of futurist Italian architect Antonio Sant'Elia.^[71] Scott hired Syd Mead as his concept artist; like Scott, he was influenced by Métal Hurlant.^[72] Moebius was offered the opportunity to assist in the pre-production of Blade Runner, but he declined so that he could work on René Laloux's animated film Les Maîtres du temps – a decision that he later regretted.^[73] Production designer Lawrence G. Paull and art director David Snyder realized Scott's and Mead's sketches. Douglas Trumbull and Richard Yuricich supervised the special effects for the film, and Mark Stetson served as chief model maker.^[74]

Blade Runner has numerous deep similarities to Fritz Lang's Metropolis, including a built-up urban environment, in which the wealthy literally live above the workers, dominated by a huge building – the Stadtkrone Tower in Metropolis and the Tyrell Building in Blade Runner. Special effects supervisor David Dryer used stills from Metropolis when lining up Blade Runner's miniature building shots.^[75]

The extended end scene in the original theatrical release shows Rachael and Deckard traveling into daylight with pastoral aerial shots filmed by director Stanley Kubrick. Ridley Scott contacted Kubrick about using some of his surplus helicopter aerial photography from The Shining.^[76][77][78]

"Spinner" is the generic term for the fictional flying cars used in the film. A spinner can be driven as a ground-based vehicle, and take off vertically, hover, and cruise much like vertical take-off and landing (VTOL) aircraft. They are used extensively by the police as patrol cars, and wealthy people can also acquire spinner licenses.^[79] The vehicle was conceived and designed by Syd Mead who described the spinner as an "aerodyne" – a vehicle which directs air downward to create lift, though press kits for the film stated that the spinner was propelled by three engines: "conventional internal combustion, jet, and anti-gravity"^[80] A spinner is on permanent exhibit at the Science Fiction Museum and Hall of Fame in Seattle, Washington.^[81] Mead's conceptual drawings were transformed into 25 vehicles by automobile customizer Gene Winfield; at least two were working ground vehicles, while others were light-weight mockups for crane shots and set decoration for street shots.^[82] Two of them ended up at Disney World in Orlando, Florida, but were later destroyed, and a few others remain in private collections.^[82]

The Voight-Kampff machine is a fictional interrogation tool, originating from the novel (where it is spelled "Voigt-Kampff"). The Voight-Kampff is a polygraph-like machine used by blade runners to determine whether an individual is a replicant. It measures bodily functions such as respiration, blush response, heart rate and eye movement in response to questions dealing with empathy.^[83] (Tyrell states: "Capillary dilation of the so-called blush response? Fluctuation of the pupil? Involuntary dilation of the iris?") In the film, two replicants – Leon and Rachael – take the test. Deckard tells Tyrell that it usually takes 20 to 30 cross-referenced questions to distinguish a replicant; in contrast with the book, where it is stated it only takes six or seven questions to make a determination. In the film, it takes more than a hundred questions to determine that Rachael is a replicant. Blade Runner 2049 uses a different but related tool called the Baseline Test.

The Blade Runner soundtrack by Vangelis is a dark melodic combination of classic composition and futuristic synthesizers which mirrors the film-noir retro-future envisioned by Ridley Scott. Vangelis, fresh from his Academy Award-winning score for Chariots of Fire,^[84] composed and performed the music on his synthesizers.^[85] He also made use of various chimes and the vocals of collaborator Demis Roussos.^[86] Another memorable sound is the tenor sax solo "Love Theme" by British saxophonist Dick Morrissey, who performed on many of Vangelis's albums. Ridley Scott also used "Memories of Green" from the Vangelis album *See You Later,*an orchestral version of which Scott would later use in his film Someone to Watch Over Me.^[87]

Along with Vangelis' compositions and ambient textures, the film's soundscape also features a track by the Japanese ensemble Nipponia – "Ogi no Mato" or "The Folding Fan as a Target" from the Nonesuch Records release Traditional Vocal and Instrumental Music – and a track by harpist Gail Laughton from "Harps of the Ancient Temples" on Laurel Records.^[88]

Despite being well received by fans and critically acclaimed and nominated in 1982 for a BAFTA and Golden Globe as best original score, and the promise of a soundtrack album from Polydor Records in the end titles of the film, the release of the official soundtrack recording was delayed for over a decade. There are two official releases of the music from Blade Runner. In light of the lack of a release of an album, the New American Orchestra recorded an orchestral adaptation in 1982 which bore little resemblance to the original. Some of the film tracks would, in 1989, surface on the compilation Vangelis: Themes, but not until the 1992 release of the Director's Cut version would a substantial amount of the film's score see commercial release.^[86]

These delays and poor reproductions led to the production of many bootleg recordings over the years. A bootleg tape surfaced in 1982 at science fiction conventions and became popular given the delay of an official release of the original recordings, and in 1993 "Off World Music, Ltd" created a bootleg CD that would prove more comprehensive than Vangelis' official CD in 1994.^[86] A set with three CDs of Blade Runner-related Vangelis music was released in 2007. Titled Blade Runner Trilogy, the first disc contains the same tracks as the 1994 official soundtrack release, the second features previously unreleased music from the movie, and the third disc is all newly composed music from Vangelis, inspired by, and in the spirit of the movie.^[89]

The film's special effects are generally recognized to be among the best of all time,^[90][91][92] using the available (non-digital) technology to the fullest. In addition to matte paintings and models, the techniques employed included multipass exposures. In some scenes, the set was lit, shot, the film rewound, and then rerecorded over with different lighting. In some cases this was done 16 times in all. The cameras were frequently motion controlled using computers.^[91] Many effects used techniques which had been developed during the production of Close Encounters of the Third Kind.^[93]

Blade Runner was released in 1,290 theaters on June 25, 1982. That date was chosen by producer Alan Ladd Jr. because his previous highest-grossing films (Star Wars and Alien) had a similar opening date (May 25) in 1977 and 1979, making the 25th of the month his "lucky day".^[94] Blade Runner grossed reasonably good ticket sales in its opening weekend; earning $6.1 million during its first weekend in theaters.^[95] The film was released close to other major science-fiction and fantasy releases such as The Thing, Star Trek II: The Wrath of Khan, Conan the Barbarian and E.T. the Extra-Terrestrial, which affected its commercial success.^[96]

Several versions of Blade Runner have been shown. The original workprint version (1982, 113 minutes) was shown for audience test previews in Denver and Dallas in March 1982. Negative responses to the previews led to the modifications resulting in the U.S. theatrical version.^[97][98] The workprint was shown as a director's cut without Scott's approval at the Los Angeles Fairfax Theater in May 1990, at an AMPAS showing in April 1991, and in September and October 1991 at the Los Angeles NuArt Theater and the San Francisco Castro Theatre.^[99] Positive responses pushed the studio to approve work on an official director's cut.^[100] A San Diego Sneak Preview was shown only once, in May 1982, and was almost identical to the U.S. theatrical version but contained three extra scenes not shown in any other version, including the 2007 Final Cut.^[101]

Two versions were shown in the film's 1982 theatrical release: the U.S. theatrical version (117 minutes),^[4] known as the original version or Domestic Cut (released on Betamax, CED Videodisc and VHS in 1983, and on LaserDisc in 1987), and the International Cut (117 minutes), also known as the "Criterion Edition" or "uncut version", which included more violent action scenes than the U.S. version. Although initially unavailable in the U.S. and distributed in Europe and Asia via theatrical and local Warner Home Video Laserdisc releases, the International Cut was later released on VHS and Criterion Collection Laserdisc in North America, and re-released in 1992 as a "10th Anniversary Edition".^[102]

Ridley Scott's Director's Cut (1992, 116 minutes)^[103] was made available on VHS and Laserdisc in 1993, and on DVD in December 1996. Significant changes from the theatrical version include the removal of Deckard's voice-over; the re-insertion of the unicorn sequence, and the removal of the studio-imposed happy ending. Scott provided extensive notes and consultation to Warner Bros. through film preservationist Michael Arick, who was put in charge of creating the Director's Cut.^[104] Scott's The Final Cut (2007, 117 minutes)^[105] was released by Warner Bros. theatrically on October 5, 2007, and subsequently released on DVD, HD DVD, and Blu-ray Disc in December 2007.^[106] This is the only version over which Scott had complete artistic and editorial control.^[104]

On Rotten Tomatoes, the film holds a 90% approval rating based on 112 reviews, with an average rating of 8.5/10. The website's critics consensus reads, "Misunderstood when it first hit theaters, the influence of Ridley Scott's mysterious, neo-noir Blade Runner has deepened with time. A visually remarkable, achingly human sci-fi masterpiece."^[107] Metacritic, which uses a weighted average, assigned the film a score of 89 out of 100 based on 11 critics, indicating "universal acclaim".^[108]

Initial reactions among film critics were mixed. Some wrote that the plot took a back seat to the film's special effects and did not fit the studio's marketing as an action and adventure movie. Others acclaimed its complexity and predicted it would stand the test of time.^[109] Negative criticism in the United States cited its slow pace.^[110] Sheila Benson from the Los Angeles Times called it "Blade Crawler", and Pat Berman in The State and Columbia Record described it as "science fiction pornography".^[111] Pauline Kael praised Blade Runner as worthy of a place in film history for its distinctive sci-fi vision, yet criticized the film's lack of development in "human terms".^[112]

Academics began analyzing the film almost as soon as it was released.^[113] The boom in home video formats helped establish a growing cult around the film,^[114] which scholars have dissected for its dystopic aspects, questions regarding "authentic" humanity, ecofeminist aspects^[115] and use of conventions from multiple genres.^[116] Popular culture began to reassess its impact as a classic several years after it was released.^{[117][118][119]} Roger Ebert praised the visuals of both the original and the Director's Cut and recommended it for that reason; however, he found the human story clichéd and a little thin.^[36] He later added The Final Cut to his "Great Movies" list.^[120] Critic Chris Rodley and Janet Maslin theorized that Blade Runner changed cinematic and cultural discourse through its image repertoire, and subsequent influence on films.^[121] In 2012, Time film critic Richard Corliss surgically analyzed the durability, complexity, screenplay, sets and production dynamics from a personal, three-decade perspective.^[122] Denis Villeneuve, who directed the sequel, Blade Runner 2049, cites the film as a huge influence for him and many others.^[119]

Blade Runner won or received nominations for the following awards:^[123]

While not initially a success with North American audiences, Blade Runner was popular internationally and garnered a cult following.^[124] The film's dark style and futuristic designs have served as a benchmark and its influence can be seen in many subsequent science fiction films, video games, anime, and television programs.^[11] For example, Ronald D. Moore and David Eick, the producers of the re-imagining of Battlestar Galactica, have both cited Blade Runner as one of the major influences for the show.^[125]

The film was selected for preservation in the United States National Film Registry in 1993 and is frequently taught in university courses.^[126] In 2007, it was named the second-most visually influential film of all time by the Visual Effects Society.^[127] The film has also been the subject of parody, such as the comics Blade Bummer by Crazy comics,^[128] Bad Rubber by Steve Gallacci,^[129] and the Red Dwarf 2009 three-part miniseries "Back to Earth".^[130][131] The anime series Psycho-Pass by Production I.G was also highly influenced by the movie.^[132]

Blade Runner continues to reflect modern trends and concerns, and an increasing number of critics consider it one of the greatest science fiction films of all time.^[133] It was voted the best science fiction film ever made in a 2004 poll of 60 eminent world scientists.^[134] Blade Runner is also cited as an important influence to both the style and story of the Ghost in the Shell film series, which itself has been highly influential to the future-noir genre.^[135][136] Blade Runner has been very influential to the cyberpunk movement.^{[137][138][139][140]} It also influenced the cyberpunk derivative biopunk, which revolves around biotechnology and genetic engineering.^[141][142]

The dialogue and music in Blade Runner has been sampled in music more than any other film of the 20th century.^[143][3] The 2009 album I, Human by Singaporean band Deus Ex Machina makes numerous references to the genetic engineering and cloning themes from the film, and even features a track titled "Replicant".^[144]

Blade Runner is cited as a major influence on Warren Spector,^[145] designer of the video game Deus Ex, which displays evidence of the film's influence in both its visual rendering and plot. Indeed, the film's look – and in particular its overall darkness, preponderance of neon lights and opaque visuals – are easier to render than complicated backdrops, making it a popular reference point for video game designers.^[146][147] It has influenced adventure games such as the 2012 graphical text adventure Cypher,^[148] Rise of the Dragon,^[149][150] Snatcher,^[150][151] the Tex Murphy series,^[152] Beneath a Steel Sky,^[153] Flashback: The Quest for Identity,^[150] Bubblegum Crisis (and its original anime films),^[154][155] the role-playing game Shadowrun,^[150] the first-person shooter Perfect Dark,^[156] the shooter game Skyhammer^[157][158] and the Syndicate series of video games.^[159][160]

The logos of Atari, Bell, Coca-Cola, Cuisinart and Pan Am, all market leaders at the time, were prominently displayed as product placement in the film, and all experienced setbacks after the film's release,^[161] leading to suggestions of a Blade Runner curse.^[162] Coca-Cola and Cuisinart recovered, and Tsingtao beer was also featured in the film and was more successful after the film than before.^[163]

Before filming began, Cinefantastique magazine commissioned Paul M. Sammon to write a special issue about Blade Runner's production which became the book Future Noir: The Making of Blade Runner.^[185] The book chronicles Blade Runner's evolution, focusing on film-set politics, especially the British director's experiences with his first American film crew; of which producer Alan Ladd, Jr. has said, "Harrison wouldn't speak to Ridley and Ridley wouldn't speak to Harrison. By the end of the shoot Ford was 'ready to kill Ridley', said one colleague. He really would have taken him on if he hadn't been talked out of it."^[186] Future Noir has short cast biographies and quotations about their experiences, and photographs of the film's production and preliminary sketches. A second edition of Future Noir was published in 2007, and additional materials not in either print edition have been published online.^[187]

Philip K. Dick refused a $400,000 offer to write a Blade Runner novelization, saying: "[I was] told the cheapo novelization would have to appeal to the twelve-year-old audience" and it "would have probably been disastrous to me artistically". He added, "That insistence on my part of bringing out the original novel and not doing the novelization – they were just furious. They finally recognized that there was a legitimate reason for reissuing the novel, even though it cost them money. It was a victory not just of contractual obligations but of theoretical principles."^[55] Do Androids Dream of Electric Sheep? was eventually reprinted as a tie-in, with the film poster as a cover and the original title in parentheses below the Blade Runner title.^[188] Additionally, a novelization of the movie entitled Blade Runner: A Story of the Future by Les Martin was released in 1982.^[189] Archie Goodwin scripted the comic book adaptation, A Marvel Super Special: Blade Runner, published in September 1982, which was illustrated by Al Williamson, Carlos Garzon, Dan Green, and Ralph Reese, and lettered by Ed King.^[190]

There are two video games based on the film, both titled Blade Runner: one from 1985, an action-adventure side-scroller for Commodore 64, Sinclair ZX Spectrum, and Amstrad CPC by CRL Group PLC, marked as based on the music by Vangelis rather than the film itself (due to licensing issues); and another from 1997, a point-and-click adventure by Westwood Studios. The 1997 video game featured new characters and branching storylines based on the Blade Runner world. Eldon Tyrell, Gaff, Leon, Rachael, Chew, J. F. Sebastian and Howie Lee appear, and their voice files are recorded by the original actors, with the exception of Gaff, who is replaced by Javier Grajeda (as Victor Gardell) and Howie Lee, who is replaced by Toru Nagai.^[191] The player assumes the role of McCoy, another replicant-hunter working at the same time as Deckard.^[146][147]

The PC game featured a non-linear plot, non-player characters that each ran in their own independent AI, and an unusual pseudo-3D engine (which eschewed polygonal solids in favor of voxel elements) that did not require the use of a 3D accelerator card to play the game.^[192]

The television film (and later series) Total Recall 2070 was initially planned as a spin-off of the film Total Recall (based on Philip K. Dick's short story "We Can Remember It for You Wholesale"), but was produced as a hybrid of Total Recall and Blade Runner.^[193] Many similarities between Total Recall 2070 and Blade Runner were noted, as well as apparent influences on the show from Isaac Asimov's The Caves of Steel and the TV series Holmes & Yoyo.^[194]

The film has been the subject of several documentaries.

A direct sequel was released in 2017, titled Blade Runner 2049, with Ryan Gosling in the starring role.^[199][200] It entered production in mid-2016 and is set decades after the first film.^[201] It saw Harrison Ford reprise his role as Rick Deckard.

Dick's friend K. W. Jeter wrote three authorized Blade Runner novels that continue Rick Deckard's story, attempting to resolve the differences between the film and Do Androids Dream of Electric Sheep?^[202] These are Blade Runner 2: The Edge of Human (1995), Blade Runner 3: Replicant Night (1996), and Blade Runner 4: Eye and Talon (2000)

Blade Runner cowriter David Peoples wrote the 1998 action film Soldier, which he referred to as a "sidequel" or spiritual successor to the original film; the two are set in a shared universe.^[203] A bonus feature on the Blu-ray for Prometheus, the 2012 film by Scott set in the Alien universe, states that Eldon Tyrell, CEO of the Blade Runner Tyrell Corporation, was the mentor of Guy Pearce's character Peter Weyland.^[204]
