Dolby Stereo is a sound format made by Dolby Laboratories. It is a unified brand for two completely different basic systems: the Dolby SVA (stereo variable-area) 1976 system used with optical sound tracks on 35mm film, and Dolby Stereo 70mm noise reduction on 6-channel magnetic soundtracks on 70mm prints.

Dolby SVA significantly improves the development of sound effects in films and theorization of sound design by Walter Murch. In 1982, it was adapted for home use as Dolby Surround when hi-fi capable consumer VCRs were introduced, and further improved in 1987 with the Dolby Pro Logic home decoding system.

THX 1138 is a 1971 American social science fiction film co-written and directed by George Lucas in his feature directorial debut. Produced by Francis Ford Coppola and co-written by Walter Murch, the film stars Robert Duvall and Donald Pleasence, with Don Pedro Colley, Maggie McOmie, and Ian Wolfe in supporting roles. The film is set in a dystopian future in which the citizens are controlled by android police and mandatory use of drugs that suppress emotions.

THX 1138 was developed from Lucas's 1967 student film Electronic Labyrinth: THX 1138 4EB, which he created 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.
