Introduction
Chinatown is a 1974 American neo-noir film, directed by Roman Polanski. The film features many elements of the film noir genre, particularly a multi-layered story that is part mystery and part psychological drama. 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 is frequently included in lists of the greatest films in world cinema. It holds second place on the American Film Institute list of Best Mystery Films. Chinatown is set in 1937 and portrays the manipulation of a critical municipal resource — water — by a cadre of shadowy oligarchs.
