Differences in two weapons in the film include that the revolver in the board game is most commonly a pepperbox revolver (an early 1800s revolver with the six bullet chambers jutting out from the main gun parts). However, it is changed to a regular .38 caliber revolver to possibly keep up with the modern time period the film is set in. The lead pipe in the game was also bent at an angle, to emphasize the fact that it was (possibly) used in Mr. Boddy's murder; the film shows it completely straight.
