Pickup on South Street (1953) 
A pickpocket unwittingly lifts a message destined for enemy agents and becomes a target for a Communist spy ring.
A solid noir-thriller from Fuller which blends gritty violence with a criminally-entwined romance. The dialogue really adds a lot to the plot here with plenty of slang that will have you reaching for your Noir Thesaurus. The cast are all believable in their various roles and Jean Peters simmers as the femme fatale caught in between Widmark's pickpocket and the Commies who hired her. As Noir goes, this is upper tier and one of my viewing high-lights of the year so far.
