Riffraff is a 1947 black-and-white international espionage film shot in the film noir style. The film, considered to be a minor noir entry more in the adventure genre, was directed by Ted Tetzlaff, who also directed The Window (1949) and worked as a cinematographer for over 100 films, including another successful suspense film, Alfred Hitchcock's Notorious (1946). Riffraff is notable for its cinematography by George Diskant, especially the stormy opening sequence.
