Continuity mistake: Barbara Rush aims a death ray to the right and above of Carlson. The scene changes with Carlson ducking and now the ray is to the left of him at waist level. The ray hits the rocks behind Carlson for several seconds, but it doesn't start breaking the rocks up on the wall until Barbara swings the ray from left to right. (01:11:45)

Continuity mistake: Rocks and soil begin to collapse all around Carlson. When he climbs back up to the rim of the crater to Barbara Rush, he doesn't have a speck of dust on his clothes. Then a few shots later (seconds) he does have dust, then he doesn't. (00:11:10 - 00:12:20)
