Visible crew/equipment: As the boat crew steps ashore to find Kilgore, the obvious shadows of two crew and their equipment are seen moving across the backs of the soldiers and then the raised netting slightly further away. This isn't the documentary crew they meet shortly afterwards, who are further onto the mainland. (00:27:20)
Continuity mistake: When the search party goes into the boneship, they are wearing full space suits, and hoods under their helmets. When Kane's helmet is first cut off, he has no hood on. (00:36:45)
Continuity mistake: In the scene where Drax's assistant, Corine Dufor, is being pursued to her death by his doberman dogs, she starts off with bare legs and high heels, but a couple of seconds later she's now wearing trainers and blue socks.
Visible crew/equipment: In the scene when Kermit confronts Doc Hopper he comes walking out of the bar. If you look at the top of Kermit's legs when he walks out, two pair of hands can be seen moving the legs.
Character mistake: USA flags are supposed to be displayed with the Union (blue area) on top left corner, whether it's displayed horizontally or vertically. USA missiles at times displayed the flag backwards. Also, at the end of the movie, the flag hung on the hangar next to the USSR flag is backward. (01:40:57)
Visible crew/equipment: In the last scene while Brian and the others are singing you can see a tourist walking in the background. (01:30:30)
