A Clockwork Orange is a 1971 dystopian crime film adapted, produced, and directed by Stanley Kubrick, based on Anthony Burgess's 1962 novel of the same name. It employs disturbing, violent images to comment on psychiatry, juvenile delinquency, youth gangs, and other social, political, and economic subjects in a dystopian near-future Britain.

Alex (Malcolm McDowell), the main character, is a charismatic, antisocial delinquent whose interests include classical music (especially Beethoven), rape, and what is termed "ultra-violence". He leads a small gang of thugs, Pete (Michael Tarn), Georgie (James Marcus), and Dim (Warren Clarke), whom he calls his droogs (from the Russian word друг, "friend", "buddy").

The film chronicles the horrific crime spree of his gang, his capture, and attempted rehabilitation via a controversial psychological conditioning technique by the Minister of the Interior (Anthony Sharp) named Ludovico. Alex narrates most of the film in Nadsat, a fractured adolescent slang composed of Slavic (especially Russian), English, and Cockney rhyming slang.

The soundtrack to A Clockwork Orange features mostly classical music selections and Moog synthesizer compositions by Walter Carlos. The artwork for the now-iconic poster of A Clockwork Orange was created by Philip Castle with the layout by designer Bill Gold.
