Richard Vanstone as Humphrey Bogart
Gets the award for "least looking like the celebrity he's portraying". At least until Leo DiCaprio played Howard Hughes (in contrast, this movie has a great Hughes).
Why couldn't they get Robert Sacchi to play Bogey? He was a bit too old in 2000, but a little makeup and he'd be spot-on (also, it's a very minor part in the movie, so great acting was not that much required).
