Corrected entry: After Bob and Charlie kill the bear, they are shown wearing clothing made from the bearskin. How did they cure the skin so fast? A raw hide would not work for garments. Tanning a bear hide of that size would take about a fortnight even if they did have the necessary chemicals and equipment, which they show no sign of having.
Corrected entry: The whole film is stupid. If they had stayed where they were, in an open area, to be seen easily, and with, say, 3/4 fires burning, to keep the bears (and other creatures) away and as signal fires, and near the water, so they can drink it and, with all of the above, they would have been found in 1/2 days. But then they wouldn't have a film, would they?
Correction: The whole point of moving was to find a more likely search area. As it was, they were 20 miles away from where anyone thought they'd be. After that, they were being chased by the bear and did what they had to do to survive long enough to be found, regardless of where it took them.
Corrected entry: In the first scene they get off the jet and into that old red plane. Anthony Hopkins character is talking to someone, and we hear the engine of the red plane starting to turn over, but if you look closely for a split second over Anthony Hopkins left shoulder the prop of the plane is not even moving. Now I know nothing about planes but I do know that the prop is attached to the crankshaft which should turn when the engine is turned over to start. (00:03:15)
Correction: That's a De Havilland Otter floatplane, and what you hear is the magneto-fired starter motor turning over. The engine hasn't fired and the propellor is still, as it should be.
Corrected entry: Near the end of the movie, when Bob falls down the dead fall, he is lying at the bottom in agony. Yet in the next scene, Charles/Hopkins plonks Bob down on the table in the lodge. Now that deadfall was some 8ft deep. How did old timer Hopkins lift a full grown man out of the pit? Bob's leg was clearly useless having had a giant spike through it. Did Hopkins have a ladder in his back pocket?
Correction: There was a rope ladder behind Hopkins. Anyone trying to trap an animal would also have to go down to get it out.
Corrected entry: In the scene where they try to hit the bear with a swinging rock, where does the rope come from?
Correction: The rope was made from strips of bark.
Corrected entry: Before the plane crashes into the lake, a bird hits the windshield and shatters the glass. When the plane does crash and sink into the lake, the windshield is seen underwater in perfect condition.
Correction: Only the pilot's windsheild is blown out from the bird strike, not the passenger's side, which is the only side shown once the plane is underwater.
Corrected entry: When Alec Baldwin has his Winchester aimed at Anthony Hopkins, just before he falls into the trap, you can see that Baldwin's left ear is filled with rubber that wasn't there before.
Correction: I do extensive wilderness survival. Everything they needed to tan the bear hide is present. A process known as brain tanning could be used and completed within a few days. Sharp stone cold be used to skin the animal and flesh the hide. The brain of the animal boiled and broken down then soaked into the hide would provide the chemicals needed.
