THX 1138 is a 1971 American social science fiction film directed by George Lucas in his feature film directorial debut. It is set in a dystopian future in which the populace is controlled through android police and mandatory use of drugs that suppress emotions. Produced by Francis Ford Coppola and written by Lucas and Walter Murch; it stars Robert Duvall and Donald Pleasence.
THX 1138 was developed from Lucas's student film Electronic Labyrinth: THX 1138 4EB, which he made in 1967 while attending the USC School of Cinematic Arts. The feature film was produced in a joint venture between Warner Bros. and American Zoetrope. A novelization by Ben Bova was published in 1971. The film received mixed reviews from critics and failed to find box-office success on initial release; however, the film has critical acclaim subsequently received and a cult following gained, particularly in the aftermath of Lucas' success with Star Wars in 1977.
Walter Murch himself did the sound design for the original film. For the 2004 Director's Cut, Tom Myers (uncredited Sound Designer/Re-recording Mixer) and Cheryl Nardi of Skywalker Sound were given special thanks for their contributions in the 5.1 remix.
In the twenty-fifth century, a time when people have designations instead of names, a man, THX 1138, and a woman, LUH 3417, rebel against their rigidly controlled society.
