Played by Jack NicholsonA quiet, hard-boiled detective and the movie’s protagonist. An intelligent man who alternates between crass jokes and politeness, Jake possesses an inherent honesty that leaves him unable to comprehend the full scope of other people’s treachery. He is a former cop whose involvement in the Mulwray case echoes a tragic but largely unexplained incident he was involved in when he worked the Chinatown beat as a police officer.
Played by Faye DunawayThe wife of Hollis Mulwray, daughter of Noah Cross, and major foil for Jake Gittes. A wealthy, elegant woman, Evelyn’s cool exterior hides an all-consuming desperation to protect her daughter, Katherine Cross, and hide the truth about Katherine’s birth. Evelyn cares for Jake but not enough to tell him the truth.
Played by John HustonThe father of Evelyn and Katherine and the major antagonist of the movie. A wealthy, well-known man, Cross’s affable front masks a sociopath who believes that no law, either legal or moral, applies to him. His crimes range from incest to land fraud to murder, all of which he commits without compunction or remorse.

Played by Darrell ZwerlingThe thin, serious chief engineer of the Los Angeles Water and Power Company.

He wants to do what is right, taking care of both Evelyn and Katherine and attempting to unravel the land fraud.
Played by Belinda PalmerThe daughter of Noah Cross and Evelyn Cross Mulwray. Katherine is a fragile creature long protected from the outside world. As Evelyn’s secret, she is seen only at a distance for most of the movie.
