In the "Russian Roulette" sequence when Malcolm holds the gun up to Rudy's face, the chamber to the (screen) right has a bullet in it. This is the chamber that Malcolm had just "fired" at his own head. Since the gun didn't fire, there would have been nothing but an empty chamber

The scene in which Malcolm and the other train porters and servers are listening to the Joe Louis vs. Billy Cohn the fight in which Louis would have cased a big stir was the June 18, 1941 fight.
