Today he is remembered for mysteries and film noir stories: My Name Is Julia Ross (1945) and So Dark the Night (1946) as well as his most highly regarded features, 1950's Gun Crazy, which spotlighted a desperate young couple who embark on a deadly crime spree, and the 1955 film noir The Big Combo, with its stunning cinematography by John Alton.
