When Chad is fighting Moon, Moon ambushes him by rolling barrels at him, causing him to drop his gun. Moon then rushes in and kicks the gun away and then lifts a barrel to throw at Chad. In the next shot, not only is Chad several feet away from Moon despite backing up slowly, but he is reaching behind his back for the gun that was just kicked away a few seconds earlier.
When Chad escapes with Danielle through a secret passageway, he kicks open a door to get outside but when the door opens you clearly see another room. The movie then cuts to the supposed other side of the door which is outside.
