When Jim Rainbolt (Clint Walker) and Shaun Garrett (Roger Moore) slide a little ways down the mountain and each hide behind their own boulder to confront their pursuers, they raise a cloud of dust. Immediately after stopping behind their respective boulders, they are both shown individually in close-up peering from behind the boulders with no dust around them at all, and immediately after that they are both shown again in the same frame behind their boulders with the dust cloud all around them that they had just raised.
