Continuity: When the boys were saying nobody messes with the Caveman, you see from behind X-Ray that both Magnet and X-Ray have their elbows on the pool table, but in the next shot X-Ray has his hands on the table and Magnet is going to put his elbows on the pool table.

Continuity: In the scene where Caveman and Zero found dirty water on the mountain, you see them splash around in it, but the next morning, in another scene, their suits are just dirty at certain spots.

Continuity: When they open the treasure at the end of the movie, Stanley hold his hand over his mouth before it opens. Then in the next shot his hands are on the table.

Continuity: At the end, right before the rainstorm comes, ZigZag jokes: "Say, I didn't know that Marian was a man's name." Mr. Sir replies: "It ain't" then ZigZag smiles and looks downward. The next shot, it zooms on Stanley (who is in front of ZigZag) and you can see that ZigZag has a blank expression on his face and is merely looking around.

Deliberate "mistake": In at least two different scenes, there are time-lapse shots of the stars moving across the sky above a horizon. Given that the location is Texas, they rotate in the wrong direction. If the horizon is southern, the stars should rotate left to right, not right to left. If the horizon is northern, they would rotate counterclockwise around a fixed point *above* the horizon, i.e. the North Pole (celestial), where the North Star would be.
