When Green saves Morse from floating down the river he gets quite wet. In the next shot his clothes are perfectly dry again.
When Morse and green stop by the river, Green states that he is tired. Morse suggests baiting some fish with gold. As you see him construct his lure he is relatively clean shaved. In the next shot as he is lowering his lure he has at least a five day growth.
Charles is pinching Stephen's nose when administering mouth-to-mouth, but in the reverse shot he is not touching Stephen's face at all and it took only a few breaths to rescue him.
When Mickey is first laying in bed her hair is up in a bun; a moment later, it is down on her shoulders.
When Morse and Styles are talking in the cabin, Morse is seen walking away with Styles. In the next shot, Morse isn't seen; instead his wife, Mickey, is walking away with Styles.
When discussing Kodiak bears, Styles says that they are highly aggressive, readily attacking and killing people without provocation. In fact, Kodiak bears are very shy, and when they encounter human beings, they typically withdraw. (Attacks do occur, but they are quite rare and almost never fatal.)
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 km/h (18 mph), 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 km/h (28 mph) 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 56 km/h (35 mph). 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%.
You can not magnetize a needle (or an unbent paper clip or watch hand) to use as a "floating compass" by rubbing it on silk. That will not magnetize it.
In the plane Robert Green (Alec Baldwin) tells his passengers that his new watch is a GMT (dual time zone) watch. However at the end of the movie we see that the actual watch of Robert is an Omega Seamaster 300M Chrono Diver and this type of watch isn't a dual time watch.
When Charles and Robert are trying to lure the bear, wind is steadily blowing the blood-soaked rag, but nothing around them, even small saplings, is moving in the "wind."
When Morse and Green fashion their bear-hide jackets there is some very neat stitching together of the pieces with straight seams in the back. This is not what you would expect in the wild. On top of that, it would take at least a week, using the necessary chemicals, to properly tan that bear's hide to make a suitable leather.
When Morse is showing Stephen the Cassiopeia constellation and the North Star, its is night time and very dark, yet a short time later when Morse goes to find Robert by the lake, it is almost bright as daytime.
When they're lifting a large tree to cross the river one of the shots reveals that the top of the tree has been sawed off a few feet above the actors' heads.
As Morse is backing up at the stream, prior to slaying the bear, his face seems to be computer generated on the body.
When they are at Styles' cabin it is obviously winter, the entire landscape is blanketed with snow. After they crash in the plane in the middle of nowhere there is no snow at all except for small patches on the mountaintops, showing that this filming took place in summer.
In a forest of tall trees with no climbing equipment or tools it would have been all but impossible to rig a booby trap, by rope, from high in the trees to swing at the bear.
The fire that Charles and Bob make at 1:11 would theoretically work, and it'd sure be nice, but it wouldn't probably happen. The amount of dryfall that would be needed to sustain just ONE fire would be an ambitious endeavor. That part of the continent gets a lot of rain, therefore anything inland is liable to be wet. Areas on the riverbank may have some wood to get started. What a person would do is get something lit - anything - and they'd be smart to use the benefit of that heat to then help dry future wood (fuel). A person could then gradually move inland, but keeping any fire going in a damp climate is an enormous task. There's little chance in those conditions, at night, without huge stockpiles of fuel, that a person could keep up with it. Not because of lack of desire, just lack of practicality.
As the characters are running from the bear in the "remote" woods, there are yellow hiking markers nailed into the trees.
Hiking is done in remote areas. All the more reason for markers.

Even if the paper clip had been properly magnetized using the knife, chances are exceedingly high that magnetic north would have been to the northeast or even east-northeast from their location, whose exact location was never given.
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.
(at around 47 min) The fire they are building to signal rescue planes is on a mountain top high above the tree line. There would be no wood to build the fire from.
At 53 minutes in, Charles and Robert both step into the cold lake up to their ankles with their shoes on. At this point they have been lighting fires and trying to dry their clothes at least 3 times. They wouldn't just walk into a lake and wet their shoes again.
When using the homemade 'compass' for the first time, it was a brilliantly sunny day and it should have been obvious to all of them, especially Charles, which direction was south.
After the flares have been lost, Bob says that he has only 6 matches left. In a later scene he is shown to have wasted a match to light a cigarette. He should have waited until they built a fire for heat or to attract searchers.
A cigarette addict in the throes of a craving doesn't think logically.

At the very beginning of the movie, when the big group lands in Charles' jet plane, the resident aircraft mechanic admires it and says, "I'd sure like to get my hands on her." Charles replies "Get your hands on who?" An erudite and accomplished orator such as Charles would certainly have used the correct objective pronoun in this case and said, "Get your hands on whom?".
