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.

Continuity: 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.

Continuity: In the scene where Lex is running in the abandoned whaler camp, the "shield" she is holding keeps changing hand between shots.

Continuity: 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. Submitted by Mortug

Continuity: 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.

Continuity: 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.

Continuity: When Miller and Lex see the penguin it travels some distance from the table it emerged from, yet in the following shot, it is a lot closer to the table.

Continuity: 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.

Continuity: In the beginning when Sebastian is uncovering the tunnel he says "We must be right on top of it", you can see he rests his right arm over the edge of the bricks. When it cuts from inside the tunnel his arm no longer over the bricks. Submitted by Mortug

Factual error: The members of the expedition are wearing their Snow Goggles on their hats with the lenses to the front. However, anyone who has ever worked in a cold weather environment (especially the guide and her "7 seasons on the ice") would know that the goggles should be worn backwards if they're not over your eyes. This keeps them from getting moisture on them.

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. Submitted by Mortug

Continuity: When the group walks along a passageway, the predators are watching from above, and in one shot the distance of the guy at the back of the group goes from about 8 feet, to almost right next to the others between shots.

Continuity: When Lex and the others in the group reach the sarcophagus, Sebastian starts to turn one of the dials, the camera cuts to Weyland for his line, he has a flashlight in his right hand, yet in the following shot its no longer there.

Continuity: 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.

Continuity: 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.

Revealing: 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. Submitted by Mortug

Continuity: 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.)

Continuity: 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.

Continuity: 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.
