Deliberate mistake: The shot of the mothership landing bay and the arrival of Charles' ship is stock footage that has been used several times before. There is also a continuity error here - the view from the landing bay shows darkness outside, but the next shot shows broad daylight. (00:06:20)
Continuity mistake: When Chris and Ham are sitting down talking about The Conversion process, Ham gets up and walks over to the map. When he turns around Chris is suddenly standing in front of him, whereas he should still be sitting down. (00:37:35)
