THX 1138 is a 1971 science fiction film directed by George Lucas in his directorial debut. The film is based on a screenplay by Lucas andWalter Murch. It stars Robert Duvall and Donald Pleasence and depicts a dystopian future in which the populace is controlled through android police officers and mandatory use of drugs that suppress emotion, including sexual desire.
THX 1138 was the first feature-length film directed by Lucas, developed from his 1967 student film Electronic Labyrinth: THX 1138 4EB, which he made in 1967 while attending the University of Southern California. This short film was itself based on a one and a quarter page treatment of an idea by Matthew Robbins.[2] Although George Lucas was not as interested in writing as he was in directing, Lucas spent 12 hours each day writing the screenplay. “I’m going to finish this, as painful as it is, and I’m going to ignore these phone calls of lure of riches and get through this. And somehow I did it”.[3] The feature film was produced in a joint venture between Warner Brothers and Francis Ford Coppola’s new production company, American Zoetrope. A novelization by Ben Bova was published in 1971.
