The kid chases Beau and the girl on a white horse without a saddle. In the next scene he is has a saddle.
When Beau (Roger Moore) goes into the cave and lights a wadded up piece of paper to read the words ("This is the place J.") on the wall, the lit piece of paper and his arm cast a shadow on the wall showing that the lighting comes from a source next to the camera and obviously not from the paper burning.
