Chinatown is a 1974 American neo-noir film, directed by Roman Polanski from a screenplay by Robert Towne and starring Jack Nicholson, Faye Dunawayand John Huston. The film features many elements of the film noir genre, particularly a multi-layered story that is part mystery and part psychological drama. It was released by Paramount Pictures. The story, set in Los Angeles in 1937, was inspired by the California Water Wars, the historical disputes over land and water rights that had raged in southern California during the 1910s and 1920s, in which William Mulholland acted on behalf of Los Angeles interests to secure water rights in the Owens Valley. Chinatown was the last film Roman Polanski made in the United States before fleeing to Europe.
