'Pickup on South Street'. Observant and tough performances, especially from the 3 principals - Richard Widmark, Jean Peters and Thelma Ritter. There's no one to really root for in the first half, and then slowly their better angels emerge. Which ironically , because its a noir, puts them at risk. Samuel Fuller's direction is more subtle than he gets credit for, and his camera movement is much more fluid than I realized. He really knew how to effectively stage a scene, and block out the actors moves. The story is just complicated enough without getting confused with inconsistent motivations. Its slowly growing reputation as one fo the better noirs of its period is deserved.
