Pink Floyd – The Wall is a 1982 live-action/animated musical surrealist drama film directed by Alan Parker, based on Pink Floyd's 1979 studio album The Wall. The screenplay was written by Pink Floyd vocalist and bassist Roger Waters, with animation sequences directed by Gerald Scarfe. The Boomtown Rats' lead vocalist Bob Geldof made his film debut as rock star Pink, who, driven to neurosis by the pressures of stardom and traumatic events in his life, constructs an emotional and mental wall to protect himself. However, this coping mechanism eventually backfires, and Pink demands to be set free. Like its associated album, the film is highly metaphorical, and frequently uses both visual and auditory symbolism throughout. It features little dialogue, instead being driven by the music from the album throughout. The songs used in the film have several differences from their album versions, and two of the songs included, "When the Tigers Broke Free" and "What Shall We Do Now?", do not appear on the album. Despite its turbulent production, the film received generally positive reviews, with praise for its music and animation, and it has an established cult following among Pink Floyd fans.
