Chinatown (1974)

Jack Nicholson is unforgettable as private eye Jake Gittes, living off the murky moral climate of sunbaked, pre-war Southern California. Hired by a beautiful socialite (Faye Dunaway) to investigate her husband's extra-marital affair, Gittes is swept into a maelstrom of double dealings and deadly deceits, uncovering a web of personal and political scandals that come crashing together for one, unforgettable night.
