2. The Day the Earth Stood Still (1951)
Here comes Klaatu and his robust robot Gort, landing their saucer in Washington, D.C. The message? Earthlings must abandon their violent ways or face annihilation. Simple, right? Wrong.

7. A Clockwork Orange (1971)
Walk with me through a dystopian Britain overrun by delinquent gangs. Alex, our "hero", undergoes an experimental therapy to cure his violent tendencies.

11. THX 1138 (1971)
Human emotion is regulated by drugs in this sterile, white-walled dystopia. THX 1138 yearns for more and rebels against the drug-induced societal norms.

12. Westworld (1973)
