A Clockwork Orange (1971) (UK-import)
Stanley Kubrick's controversial film triggered copycat violence on its initial release and as a result the director withdrew the film from circulation in Britain, keeping it suppressed right up to his death in 1999. The film follows sadistic punk Alex (Malcolm McDowell) as he takes his gang on a rape and murder spree, showing absolutely no mercy to any of his victims. When he is eventually captured, the authorities subject him to a series of experiments designed to rid him of his violent tendencies.
