"A Bullet for Joey" (1955) Noir about a deported gangster (George Raft) that is recruited by a foreign power to kidnap a Canadian atomic scientist, with Edward G. Robinson as the inspector hot on his trail.
"The Killer That Stalked New York" (1950) another film noiresque with a virtual who's who of noir films and early TV shows. Every scene you say "hey it's that guy/girl!".
