Factual error: When one of the crazy brothers and a Sudanese guy are climbing the mountain they come to a place where the muslim guy starts praying. The way he prays wrong. During a muslim prayer your hands are raised to your ears for a few seconds and lowered again, but the guy keeps his hands raised and prays. Plus you cannot talk while your praying or look away as the guy does to motion towards the nitro.

Audio problem: When the three of them fall into that "cave" one of the men coughs without his mouth moving.

Continuity: When one of the guys falls of a cliff, I don't remember who, he stabs his hammer into the cliff. After a few seconds the hammer goes up a bit, even though he is hanging on it.

Revealing: In the opening shots of the film there is an eagle flying around the buttes. It is an obviously digitally rendered eagle as it is transparent at some points. This is very evident when the eagle passes from in front of a butte to the open sky and it's obviously not a shadow.

Continuity: The boiling nitroglycerin in the shed, on the floor, around the boot is bubbling in different places depending on the shot.

Factual error: When the photographers are hiding in the blind, shooting the bears, they have a table sitting behind them covered in extra gear. All the extra film that's sitting around is Kodak Max 400, a supermarket film, and nothing that a professional wildlife photographer would be using.

Continuity: Somehow, despite Mrs. Wick's corpse being encased in a block of ice (and her back, and presumably backpack is the deepest buried part of her), and only being uncovered for two minutes, Chris O'Donnell's character finds her empty medicine case, without Jonathan Wick noticing.

Factual error: Throughout the movie they throw around their bags, shake them around and throw themselves onto them with the nitro strapped onto the bags. They should have got blown to pieces at least a dozen times. It's only when it's time to pour the nitro in the snow to blow a hole they are careful.

Continuity: 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.
