Continuity mistake: When the girl is about to lower the boy down on the rope to save their dad, she loops the rope through the carribena, but she never actually does it up.
Continuity mistake: The kids are repelling down a steep icy ridge. The polar bear is at the top of the ridge above them. The girl is on her way down, and her brother says something to the bear cub. Before he speaks he is holding onto the rope that his sister is attached to, then they cut to a shot of the bear, then back to the boy and he is now holding an axe, with the rope nowhere to be seen.
Continuity mistake: When the kids are climbing down the icy hill, Sean holds an ice axe that keeps switching hands in different shots.
Continuity mistake: When the kids are climbing down the steep icy hill, Sean falls and hits his head on a rock. When he lies unconscious, his head is right next to the rock, but in the next shot we see of him, he's a few feet away.
Continuity mistake: When Shawn and his Dad are arguing, Shawn puts down his fork in one shot, and in the next shot, he has it back in his hand. In the next shot, it's back on the table and he picks it up again.
Continuity mistake: When the boy slides down the hill on the snow/ice and hits his head, he looses his hat. When they are shown hiking in the woods a couple minutes later, he has it.
Visible crew/equipment: Toward the end of the movie when the kids are pulling up their dad, just about when he is at the top of the mountain, on the right side of the screen you can see a steel platform and a guy's left leg and foot, he is wearing blue pants and a brown shoe. You can also see the pole holding up the platform and a shadow. To see this you must have the widescreen showing and be very quick, it is only there for less than a second.Jeff Duncan
Revealing mistake: When the kids are being washed down the rapids they desperately hang onto a log across the river. As the girls climbs up, one of the branches rotates when she grabs it and is a round peg in a hole.
