Corrected entry: Near the end of the movie, when Jerry is holding Jonas underwater with a mop, Jonas pulls out a six-shooter (revolver) from an ankle holster and shoots Jerry in an attempt to save himself. There are two inherent mistakes here: One, revolvers don't fire under water; two, even if it had been a double-action so he wouldn't have to cock it, the hammer never moves.

Correction: 1. Any firearm may fire underwater. It depends on the brand of ammo and how long it has been submerged. 2. The hammer was shown from the rear, not from the side, making its movement far less obvious. It was shown while firing for less than a second, underwater, making any hammer movement very difficult to see.
