This is one of the all-time great examples of film noir. It can practically be used to define the genre: shadowy black and white cinematography; a star-crossed protagonist ("...fate sticks out a leg to trip you."); a femme fatale (the unforgettable Ann Savage as Vera); cynical voice-over narration; ambiguous morality. All these elements are brought together magnificently by director Edgar G. Ulmer, who incredibly made this movie in several days on a shoestring budget. His direction is so masterful that the low budget sets only add to the film. This is a great masterpiece and one of the marvels in film history.
