“You may think you know what you’re dealing with, but believe me, you don’t,” warns water baron Noah Cross (John Huston), when smooth cop-turned-private eye J.J. “Jake” Gittes (Jack Nicholson) starts nosing around Cross’s water diversion scheme. That proves to be the ominous lesson of Chinatown, Roman Polanski‘s critically lauded 1974 revision of 1940s film noir detective movies. In 1930s Los Angeles, “matrimonial work” specialist Gittes is hired by Evelyn Mulwray (Faye Dunaway) to tail her husband, Water Department engineer Hollis Mulwray (Darrell Zwerling).
