Clockwork Orange (1971)

The controversial 1971 adaptation of Anthony Burgess’s button-pushing novel remains both utterly repellent and utterly compelling...

In an England of the future, Alex (Malcolm McDowell) and his "Droogs" spend their nights getting high at the Korova Milkbar before embarking on "a little of the old ultraviolence," while jauntily warbling "Singin' in the Rain." After he's jailed for bludgeoning the Cat Lady to death, Alex submits to behaviour modification technique to earn his freedom; he's conditioned to abhor violence. Returned to the world defenseless, Alex becomes the victim of his prior victims.
