Continuity mistake: In the beginning when the man realizes the Predator is in the same room, he falls to the ground and backs up against an oven.

Visible crew/equipment: During the briefing Weyland says "But it's not on the ice, it's two thousand feet below it" it cuts to a shot behind Maxwell with an overview shot of the crew. If you look behind Maxwell you can see the tip of a head moving into picture. In the previous shot we could see no one was standing behind Maxwell, and it couldn't be Sebastian cause he went back to his seat. (00:07:55)
