Factual error: While Anthony and the two others are staring at the bear as it screams, you see a large cold-blooded lizard scuffle up the tree right behind the bear's head when the young man says, "C'mon, let go!" No way that would live in the area they're supposedly in. (00:44:35)
Factual error: Charles and Robert manage to outrun a charging Alaskan brown bear over a course of several hundred meters, leading it into a trap. This is absurd. The absolute maximum running speed of a human being is about 27 kilometers an hour, and that is for an appropriately dressed, fit athlete over a very short course on flat ground. They are in a rock strewn stream and are wearing heavy winter clothes. A fit, healthy, active male Alaskan brown bear like the one chasing them could hit 45 kmh in that environment without popping a sweat and could keep that up for a kilometer or more. When enraged or charging prey - as this one was - they have been clocked at 56kmh. This is nothing to do with an adrenaline rush - that will not enable Charles or Robert to exceed their body's maximum running speed by 200%.
Continuity mistake: In one of the scenes Hopkins is trying to make what I think is a fish hook or something. He's obviously been in the wilderness for a while so he's not clean shaven but he isn't exactly beardy either. However, during the scene with this fish hook his beard changes from moderate to bushy to moderate again within seconds.
Continuity mistake: When Charles is showing Steve the constellations, the sky is pitch black. Yet in the next scene when Charles goes down to the shore to Bob, the sky has brightened considerably. No indication is given that a good deal of time has passed between these two scenes.
Revealing mistake: When the needle is set in the pool of water in a stump to act as a compass the pool has been carved out with a chain saw very recently and clumps of the wrong moss set around the rim like it belonged there.
Other mistake: I've always wondered where they got the wood to make the enormous fire on the top of the mountain. You can clearly see that there are no trees anyway nearby, (except for several hundred meters further down) and they are not carrying wood with them either.
Revealing mistake: In the last scene, when Anthony Hopkins and Alec Baldwin are trying to kill the bear, they appear to have sharp wooden spears. As the camera angle changes you can notice that Hopkins is holding a green/brown training pole instead of a natural wood spear.
Visible crew/equipment: While the 3 men are using a tree to cross a gorge during their first encounter with the bear, you can see a black metal box with white writing on it, sitting on a rock formation in the background. Definitely filming equipment or something. You can get a glimpse of it directly behind Charles as the 3 of them sit and gather their breath once the action breaks.
Plot hole: They show the two men trapped inside a ring of fires that they have built, (and must constantly maintain to keep the bear at bay), as the sun is setting. And, somehow, when the sun rises, they have created enough rope, (just from grass and bark, I guess), to tie a huge boulder from way up in a tree - all wrapped with ropes and spikes, and have somehow deployed that, and stationed a bunch of other sharpened spears in various places, over hundreds of yards.
Continuity mistake: When Charles is performing CPR on a man who drowned when the plane went down, in one angle he's pinching the nose closed, as he should, but from a different angle he's not.
Answer: That would only work when the sun is visible. In Alaska there are frequent rainy and overcast days where the sun is completely blocked by heavy clouds, making a precise directional determination difficult, if not impossible.
