The Maltese Falcon

The Maltese Falcon is an American 1941 Warner Bros. film based on the novel of the same name by Dashiell Hammett. Written and directed by John Huston, the movie stars Humphrey Bogart as private investigator Sam Spade, Mary Astor as his femme fatale client, Sydney Greenstreet in his film debut, and Peter Lorre. The film was Huston's directorial debut and was nominated for three Academy Awards.

The story concerns a San Francisco private detective's dealings with three unscrupulous adventurers who compete to obtain a fabulous jewel-encrusted statuette of a falcon.

The Maltese Falcon has been named as one of the greatest films of all time by Roger Ebert, and Entertainment Weekly, and was cited by Panorama du Film Noir Américain, the first major work on film noir, as the first film of that genre.
