Chinatown (1974), directed by Roman Polanski and written by Robert Towne, stars Jack Nicholson as private detective J.J. Gittes drawn into a Los Angeles water corruption scandal that leads to revelations far darker than he could have imagined. Faye Dunaway plays the enigmatic Evelyn Mulwray.

Why It Matters

• The definitive neo-noir — a film that understands and deconstructs the classic detective genre while devastating it emotionally
• Robert Towne's screenplay is taught in virtually every screenwriting program as a model of structure and revelation
• Polanski insisted on the original ending against Towne's wishes — one of cinema's most brutal and nihilistic conclusions

Set in 1930s Los Angeles with impeccable period design by Richard Sylbert, the film argues that corruption is not an aberration in American power structures — it is the system. Its famous last line remains a gut punch.
