When You're Strange is a 2009 music documentary film about the American rock band the Doors. It was written and directed by Tom DiCillo and narrated by Johnny Depp. The film covers the band's formation in 1965, its development over the next two years, the release of its debut album and subsequent albums, and vocalist Jim Morrison's extensive use of alcohol and drugs, which led to his death in Paris in July 1971. The film features archival footage of rehearsals, TV broadcasts and concert performances, private cine-film and the background to Morrison's arrest at a 1969 Miami concert and later trial. It also includes the first public release of material from Morrison's 1969 short film HWY: An American Pastoral.

The Doors were an American rock band formed in Los Angeles in 1965, with vocalist Jim Morrison, keyboardist Ray Manzarek, guitarist Robby Krieger and drummer John Densmore. They were among the most influential and controversial rock acts of the 1960s, primarily due to Morrison's lyrics and voice, along with his erratic stage persona and legal issues. The group is widely regarded as an important figure of the era's counterculture.
