Revealing mistake: When Wick is rubbing his toeless feet, the shot changes so that the camera is behind him and you can see him still rubbing except now you can see that he is simply curling his toes over.
New this month Factual error: When Annie finds the Dex in the backpack that she has just gotten from the ledge, she goes to give it to Tom immediately. It would have been frozen or extremely cold and unless warmed by her, it never would have come out of the syringe easily.
Continuity mistake: When the rescue team are jumping from the helicopter to the side of the mountain, the chopper suddenly swings causing Monique to dive for cover. When she dives to the floor there is nothing around her only snow and ice, yet in the following shot when the propeller blades are close to her, a large rock has appeared to her right which wasn't there in the previous shot.
Factual error: When the expedition is unloading from the helicopter, it shows a view of the lady with the helicopter blades about to cut her head off. It then shows a view of the helicopter, perfectly upright, and people are still jumping off! She then gets up and crawls to the rock wall, which in a full view you can see that it is at least 15 feet away from the edge. The helicopter blades follow her, perfectly parallel with the ground. It is physically impossible - the helicopter would have to be underground for this to happen.
Continuity mistake: Peter walks into a tent where Monique tells him where to find Skip. The stubble he has when talking to Monique is totally gone when he finds Skip, immediately afterward.
Continuity mistake: When the first climb the "K2" mountain Annie is breathing perfectly without opening her mouth, while the others are gasping for air. She notices she's not breathing hard and all of a sudden her mouth opens wide and she starts gasping too.
Continuity mistake: When Vaughn, Annie and Tom have fallen down inside the mountain, the camera cuts to Skip trying to call them on the radio. When the camera cuts to some people behind him, a big man is leaning towards another man sitting with a headset on. In the following shot facing Skip, that man is now standing up in the background .
Revealing mistake: Those are the most haphazardly secured cases of nitro I've ever seen in a movie. Couldn't they spare a shoelace or duct tape to secure the top?
Continuity mistake: When Chris O'Donnell blows a hole over the ice cave, his sister is directly below the hole, even though she was shown running into a side cave for protection.
Visible crew/equipment: After the father tells Chris O'Donnell to cut the rope, and there is a zoom shot of a nervous O'Donnell, the camera cuts to where the father will fall. If you look at the top of the screen, you can see part of the father's harness dangling.
Continuity mistake: In the first several shots of Wick's frozen wife, her jacket hood sits partway down her forehead. When Wick approaches her, the hood has moved up higher on her head, so you can see her entire forehead and some of her hair.
