John Cho (born Cho Yo-han ; June 16, 1972)  is a Korean American actor and musician. He is best known as Harold Lee in the Harold & Kumar films; John (MILF Guy No. 2), who popularized the term " MILF " in the American Pie films; and Hikaru Sulu in the Star Trek reboot film series. Early in his career, Cho also starred in the Asian American centered films Better Luck Tomorrow (2002), Shopping for Fangs (1997), and Yellow (1998).
On television, Cho played FBI agent Demetri Noh in the science fiction television drama FlashForward ; Chau Presley on the sitcom Off Centre ; Andy Brooks in the horror drama Sleepy Hollow , Henry Higgs in the 2014 sitcom Selfie , and Andrew Kim in The Exorcist .
Cho was born in Seoul, South Korea,  and moved to the United States in 1978 as a young boy. He was raised in Los Angeles, where his family settled after living in Houston, Seattle, Daly City, California, and Monterey Park, California.  His father was a minister in the Church of Christ, and was originally from North Korea.   Cho graduated from Herbert Hoover High School,  in Glendale, California, in 1990. He then attended the University of California, Berkeley,  graduating in 1996 with a BA degree in English,  and taught English at Pacific Hills School in West Hollywood, California while working at East West Players's theater in downtown Los Angeles.
Cho began his career after graduating from Berkeley, when he moved to Los Angeles and worked with the Asian American theatre company East West Players.  There, he appeared in Edward Sakamoto's The Taste of Kona Coffee in 1996, and in Euijoon Kim's movie My Tired Broke Ass Pontificating Slapstick Funk in 2000.  He gained attention with a small role as "MILF Guy #2" in the 1999 comedy American Pie , in which he popularized the slang term " MILF ".  Cho reprised the role in three sequels: American Pie 2 , American Wedding , and in the latest installment American Reunion in which he has a much larger role. The character initially had no name but he was given the name "John" in the third film, named after Cho himself.
He had a successful starring role as Harold Lee in 2004's Harold & Kumar Go to White Castle and reprised the role in 2008's Harold & Kumar Escape from Guantanamo Bay, which raked in $38 million at the theaters,  and again in 2011's A Very Harold & Kumar 3D Christmas which made $35 million.  Cho's role in the popular franchise was written specifically for him by Hayden Schlossberg, and Cho has recounted that when Schlossberg first approached him with the role, he was initially suspicious.
Cho guest-starred on Charmed as a ghost in 1998 and was one of the stars of the short-lived situation comedy Off Centre in 2001–2002. He was a costar of the now-defunct Fox sitcom Kitchen Confidential based on Anthony Bourdain's best-selling book.  He had supporting roles in Evolution , a sci-fi comedy directed by Ivan Reitman, Down to Earth , starring Chris Rock, and Bowfinger , with Steve Martin.
In 2002, he had a starring role in the ensemble cast of Justin Lin's Better Luck Tomorrow , a drama focusing on the travails of a group of Asian Americans living in Southern California who are academically successful but socially discontented, and as a result engage in wantonly violent, criminal behavior. It was well received by critics, with the New York Times's Elvis Mitchell describing Cho's character's "lazy magnetism of which he is charmingly aware." Later that year, the movie Big Fat Liar was released, in which Cho played a Hong Kong-based movie director. He refused to do the accent scripted for his character. The director worked with him to re-develop the role.
Cho appeared on July 2004 issue of KoreAm Journal and in September 2006 was cast in NBC's new comedy The Singles Table , but the series never aired due to changes in scheduling and production. In 2006 and again in 2009,  Cho was selected as one of the sexiest men alive in People Magazine.
In 2007, Cho was added to the cast of Ugly Betty as a recurring character. Cho plays Kenny, a best friend of accountant Henry Grubstick (played by Christopher Gorham). Cho played helmsman Hikaru Sulu in J. J. Abrams's feature film Star Trek .   Manohla Dargis of The New York Times praised him, along with Anton Yelchin, Chris Pine, and Zachary Quinto, for making their roles "ultimately and rather wonderfully their own".
Cho appeared in Nas' " Be a Nigger Too " music video along with various celebrities, and had a guest appearance on the sitcom How I Met Your Mother , in the episode " I'm Not That Guy " where he played a partner in an evil law firm. Of the latter, Staci Krause of IGN, wrote that Cho was "the scene stealer in this episode" and that she would "definitely like to see more of him" in the series. 
From 2009 to 2010, Cho starred in the television series FlashForward as FBI Special Agent Demetri Noh.  His character was originally slated to be killed off during what turned out to be the show's only season, but after his turn as Sulu in Star Trek boosted his popularity, the producers revised the show's storyline so that he survived, in an attempt to boost declining ratings. 
He is the lead singer for Viva La Union (formerly known as Left of Zed),  a Los Angeles garage rock band composed of former Berkeley and USC students. They have one album, self-titled, while their song "Chinese Baby" is featured on the Harold & Kumar Escape from Guantanamo Bay soundtrack.
Being an Asian American in Hollywood
Cho has indicated he has found freedom in being Harold in the Harold and Kumar films because the stoner character goes against the grain of Asian Americans onscreen.  He has said he has experienced racism throughout his career in Hollywood and that he tries to take roles that do not perpetuate Asian stereotypes. 
When asked to do an Asian accent for Big Fat Liar , Cho refused. “I don’t want to do this role in a kid’s comedy, with an accent, because I don’t want young people laughing at an accent inadvertently”, he wrote. In a 2015 tweet he said, "Stop turning Asian roles white. It's bullshit and we all know it."  On being the first Asian to play a romantic lead on a U.S. television series, he described it as being “revolutionary” and a “personal revolution” for him because of its uniqueness in Hollywood. “Asians narratively in shows are insignificant. They’re the cop, or waitress, or whatever it is. You see them in the background. So to be in this position ... is bit of a landmark,” he has said on the inability of Asians getting offered such roles. 
Cho married actress Kerri Higuchi in 2006 and has a son, born in 2008,  and a daughter, born in 2013.  As of at least 2015, reside in Los Angeles, California.  He supported the 2012 re-election campaign of Democratic U.S President Barack Obama. 
He is very close to his father, a former preacher, and would like to play a role in the story of his father's generation in North Korea when growing up through the Korean War in times of hardships.  In a tweet he said, "Dear Dad: sometimes I need advice, sometimes I don't. Sometimes I am just telling you stuff. Thanks. Love you."
