Made it, Ma, top of the world!" James Cagney is riveting as homicidal gangster Cody Jarrett (complete with an "insane mother" complex) in this hard-boiled movie that costars Virginia Mayo as his two-timing wife. Edmund O'Brien's the cop who infiltrates Cody's gang to bring him down -- and that he does in the legendary finale that plays out in an industrial yard filled with giant fuel tanks. Better watch those stray bullets! Raoul Walsh directs.
