Pickup on South Street (1953) - I watched this movie for the Film Noir HoF. It's one of the few movies nominated that I hadn't seen already, so it was a first-time watch for me.
Candy, (Jean Peters), is on a crowded subway train when pickpocket Skip McCoy, (Richard Widmark), steals her wallet. She was delivering an envelope for her ex-boyfriend, Joey, (Richard Kiley), unaware that he is a communist spy, and the envelope contained sensitive information on film. She also didn't know that she was being followed by government agent Zara, (Willis Bouchey), who witnessed McCoy stealing the film. Police informant Moe Williams, (Thelma Ritter), is brought in to help identify the thief. As the story progresses, it quickly changes from a simple crime drama to an exciting spy thriller.
The movie has some minor issues, for example, I thought the opening scene was either confusing or possibly intentionally deceptive because Candy looks like she is staring at Skip as if she knows that he's taking something out of her purse, like it's a prearranged pickup, but overall, this is a great movie. The acting is superb, with excellent performances by the entire cast, especially by Richard Widmark and Jean Peters, and a standout performance by Thelma Ritter.
If you're looking for a good thriller, I highly recommend this movie.
