Joseph H. Lewis was an American B-movie film director whose stylish flourishes came to be appreciated by auteur theory-espousing film critics in the years following his retirement in 1966. In a 30-year directorial career, he directed numerous low-budget westerns, action pictures, musicals, adventures, and thrillers. 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.
