 When James Spader turns and shoots at Ra instead of his comrades so that   they can flee, there are several extended cuts put in.  Originally they were   just ushered away by the natives, in the special edition they ride away on   one of the Mastadges. Kurt Russell and James Spader are then seen lost in a   sandstorm and found by the boys, and taken to the caves (which is in the   theatrical edition); an additional scene after this sees the boys feeding   the Mastadges outside the caves.
