Great site for old movies and actors:
Greenbriar Picture Shows
My otherhalf loves Turner Movies and wants to throw some names into your thread:
African Queen with Humphrey Bogart and Kathrine Hepburn ... never forget seeing him get down into the water and pull her boat then get out covered in Leeches.
Sydney Greenstreet and Peter Lorre in The Maltese Falcon.
Humphrey Bogart in the Treasure of Sierra Madre
Richard Widmark in just about anything
Humphry Bogart & Ingrid Bergman in Casa Blanca
James Cagney in Public Enemy, is that the one where he squashes a grapefruit into a girl's face?
