Gun Crazy (also known as Deadly Is the Female) is a 1950 film noir directed by Joseph H. Lewis, and produced by Frank King and Maurice King. The production features Peggy Cummins and John Dall in a story about the crime-spree of a gun-toting husband and wife. The screenplay by blacklisted writer Dalton Trumbo—credited to Millard Kaufman because of the blacklist—and by MacKinlay Kantor was based upon a short story by Kantor published in 1940 in The Saturday Evening Post. In 1998, Gun Crazy was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant."
