We have one for Bogart, as we should. Now how about James "Jimmy" Cagney? I expect a lot of people here would plump for White Heat -- -- not least because it is probably the greatest cops-'n'-robbers movie ever, and his astonishing performance makes it go. And then there's The Roaring Twenties, which combines Cagney and Bogart; and even his late film One, Two, Three is a delight. What say all of you?
