"Chinatown," generally regarded as the Great American Screenplay, follows a seedy private investigator, Jake Gittes, as he becomes involved in a case far more complicated than he ever imagined. Instead of adultery and divorce, he uncovers a conspiracy reaching to the economic foundations of Los Angeles. Set in the 1930s, the film was directed by Roman Polanski and stars Jack Nicholson, Faye Dunaway, and John Huston.
