A Clockwork Orange is a 1971 science fiction film written, directed and produced by Stanley Kubrick, adapted from Anthony Burgess' 1962 novella of the same name. It features disturbing, violent images, facilitating its social commentary on psychiatry, youth gangs, and other social, political, and economic subjects in a dystopian, future Britain.
Alex (Malcolm McDowell), the main character, is a charismatic, sociopathic delinquent whose interests include classical music (especially Beethoven), rape, and what is termed "ultra-violence". He leads a small gang of thugs (Pete, Georgie, and Dim), whom he calls his droogs (from the Russian друг, "friend", "buddy"). The film chronicles the horrific crime spree of his gang, his capture, and attempted rehabilitation via controversial psychological conditioning. Alex narrates most of the film in Nadsat, a fractured adolescent slang comprising Slavic (especially Russian), English, and Cockney rhyming slang.
