Continuity mistake: At the very beginning of the film, when the amateurs fall, one of the amateurs swings past Royce Garrett. In the next shot when the ropes comes away from the wall, the two amateurs are a lot higher up, and when the amateurs' rope falls, if you slow this shot down it misses Royce Garrett, yet in the following shot he gets snagged off the wall by the rope. (00:03:25)
Continuity mistake: The Pakistani helicopter pilot taking Peter to the camp at the start is wearing headphones. In one shot the right headphone (our left) is half over his ear. In the next it is fully over his ear. And then back again.
Continuity mistake: When Peter, Annie and their dad are on the wall, Peter makes his jump up to the next grip, and as the camera pans out the rope goes straight to the dad. In the next shot there is a carabineer in the wall holding the rope just above Peter, then the rope carries onto the dad. (00:01:50)
Continuity mistake: Close to the beginning of the film, when Annie and Peter are talking in the tent before she goes up to climb, in one shot she says "of course I remember," and she turns her head and looks at him. In the following shot she is turning her head again as well as her body to face him. (00:25:20)
Continuity mistake: When O'Donnell is about to jump from one side of a cliff to the other,the first shot shows the other side higher than the one Chris is. In all the other shots the other side is lower.
Continuity mistake: When the guys are unloading from the chopper, you can see the pilot is going through hell to keep it stable. And he obviously can't. There's a master alarm flashing all over and the pilot even says something like "get out, we're gonna fall". However, the girl is almost getting shattered by the chopper blades, which keep going round above her head as if the helicopter was really stable.
Continuity mistake: The boiling nitroglycerin in the shed, on the floor, around the boot is bubbling in different places depending on the shot. (00:45:25)
Continuity mistake: When the rescue crew jumps off the helicopter you can see there's a big snow storm and the pilot says this is the highest point at which he can drop them off . But later on (just a few minutes later) the sun is shinning high and it looks nothing like it was.
