Factual error: When they're first entering the whaling camp, a penguin startles Miller. That penguin was a black-footed penguin, which is a bird native to much warmer climates. If that little guy had actually been in Antarctica, he would have died within minutes. (00:20:40)
Continuity mistake: In the scene where Lex is running in the abandoned whaler camp, the "shield" she is holding keeps changing hand between shots. (01:18:05)
Continuity mistake: Early in the movie the female protagonist "Lex" Woods is climbing an ice waterfall. The scene shown from a distance reveals a steep ascent above the ice, but in the next scene, she reaches a large area flat enough for a helicopter to land upon. (00:03:40)
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)
Continuity mistake: When Lex and the predator are going up the tunnel at the near the end of the movie. Lex has the alien head shield on her left arm. But when they are speeding up the tunnel, the shield is not on either arm. If you pause it, you can see the shield missing. When they emerge out of the tunnel it is back on her arm. (01:17:05)
Suggested correction: The shield didn't vanish. Lex removed it so that she could hold the sled with both hands. The shield is right between Lex and the predator. (1:26:58) When they emerge out of the tunnel, the shield is on her right arm.
Continuity mistake: When the group are in the pyramid, just after they have discovered the weapons inside the sarcophagus, they begin to take them out. When Sebastian says, "Don't touch them", all the doors start to close, and Lex runs past a guy twice. (Slo-mo may be necessary.) (00:40:15)
Continuity mistake: When the predators are watching the humans in a room, Weyland drops one of the guns from his backpack. Its position and distance on the floor from Weyland's boots changes between shots. (00:50:45)
Continuity mistake: When Sebastian says that the experts are right he gets up and says "All of them" you can see his hands are down. When it cuts to Lex saying "Meaning what exactly? Sebastian has his left hand by his waist. (00:09:05)
Continuity mistake: When Sebastian comes out of the hole to reveal the video camera he found, his red t-shirt has no mud/dirt on the front, but in the following shot when Sebastian is walking to the tent, there is a rather large long streak of mud/dirt on his t-shirt. (00:05:15)
Continuity mistake: Lex's initiation mark disappears in overhead shots.
Factual error: The expedition leader claims that Bouvet Island is not under any national control, because of the Antarctic Treaty. However, because of its remoteness from the continent of Antarctica, Bouvet Island is actually not included in this treaty and Norway has full ownership of this island. (00:12:35)
Factual error: When arriving in Antarctica, there is dialogue about the full moon (la luna di cacciatore, etc...) There is no full moon on 10/10/2004 in Antarctica. But it does look nice in the movie... (00:12:15)
Continuity mistake: When Lex Miller and Sebastian are talking at the side of the ship at the beginning, Miller says "Ii wish you'd consider coming with us ", it cuts to a shot from the side/back, she is looking either in Sebastian's direction or out to sea, yet in the following shot she is looking at Miller's face. (00:12:50)
Continuity mistake: When Lex is in Weyland's office on the ship, in one shot her arms are crossed, in the following shot, her hands are on the table, then back to crossed. (00:11:45)
Continuity mistake: When Lex is on her way to meet Weyland, Miller asks her to take a picture. When she first takes the camera, she puts her fingers on top, ready to take the picture, then she does it again. (00:06:25)
Continuity mistake: When Sebastian is checking the sand inside the tunnel, right before he finds the Pepsi Cola cap, you can see a close-up of his wrist and there is no sign of his watch. When it cuts his watch is visible. (00:05:00)
Continuity mistake: Close to the beginning, when the group is inside the pyramid below the sacrificial chamber, when the shot is from behind Lex and the others, note where the green light is, directly in the middle of the stairs. When it cuts to an overhead view, it's more to the left than the right. (00:36:50)
Revealing mistake: There is a wide shot of the ship were there is some equipment on the ice and some people moving around. The ship itself and the equipment cast shadows. But none of the moving people cast any shadows at all. (00:14:25)
Continuity mistake: When Miller places his camera on the cabinet to take a picture of himself, the string from the camera changes position between the shots. (00:19:50)
Revealing mistake: After the predator drops Weyland, as the predator turns, you can see the skin of the actors neck.
