During Bob Steele's fight with Roger Caldwell,Steele's hat keeps disappearing and reappearing on his head without ever having been knocked off.
In the climactic fight, Hoot Gibson throws lit sticks of dynamite at the fleeing bad guys. The resulting explosions occur several feet from where the sticks actually land, and when the dust clears, you can see the "dynamite" sticks he threw still lying on the ground.
