Dementia 13 is a 1963 horror thriller released by American International Pictures, starring William Campbell, Patrick Magee, and Luana Anders. The film was written and directed by Francis Ford Coppola and produced by Roger Corman who asked for a film that would capitalize on the success of Alfred Hitchcock's Psycho.
Corman offered Coppola the chance to direct a low-budget horror movie in Ireland with funds left over from Corman's recently completed The Young Racers, on which Coppola had worked as a sound technician. The producer wanted a cheap Psycho-copy, complete with gothic atmosphere and brutal killings, and Coppola quickly wrote a screenplay in accordance with Corman's requirements. Although he was given total directorial freedom during production, Coppola found himself fighting with Corman after the film was completed. The producer declared the movie unreleasable and demanded several changes be made. Corman eventually brought in another director, Jack Hill, to film additional sequences.
