Errors made by characters (possibly deliberate errors by the filmmakers): Easy Andy introduces the .44 Magnum revolver by claiming it will "stop a car at a hundred yards, put a round right through the engine block." Such a bullet will not penetrate an engine block at that range, and the shooter will have little hope of damaging or disabling a component of the engine that will disable the vehicle (such as shorting out the battery or causing the coolant to drain out). However, it is fairly obvious that this is part of his sales bluster.
