The second of three film adaptations of Dashiell Hammett's "The Maltese Falcon," this film has notable connections to both other versions. First, this film's screenwriter, Brown Holmes, was also credited as a screenwriter on The Maltese Falcon (1931), directed by Roy Del Ruth. Second, this film's cinematographer, Arthur Edeson, was also the director of photography for John Huston's The Maltese Falcon (1941). Third, Warren William, who plays the Sam Spade character (Ted Shane) in this film, also played Perry Mason in a series of films beginning in 1934, but was replaced in 1936 by Ricardo Cortez - who had played Sam Spade in the 1931 "Maltese Falcon". Finally, Bette Davis filled in for Raymond Burr when he had to have surgery in Perry Mason: The Case of Constant Doyle (1963).
