Hi Carl -
I caught the last ten minutes of "White Heat" on TCM yesterday evening myself. Unfortunately, I was only taking a supper break and had to get back to the office to help put the paper to bed.
Bogart, Cagney & Robinson were all great actors. One of my favorite movies is "Dark Passage" where we don't even see Bogart's face for almost halfway through the film. And, of course, paired with his wife, Lauren Bacall, made for special chemistry.
Another one of my favorites pairing Bogart and Bacall is "Key Largo" with the addition of Robinson in one of his best roles.
Cheers - Jay
