Corrected entry: This movie has these dogs playfully barking almost constantly. These breeds of dogs, particularly Huskies, rarely, if ever, bark in a playful way. The only point in the movie where I would expect to hear barking would be during the leopard seal attack and it would be a very angry bark with a growl. Although mostly quiet, when happy, these breeds also groan, growl, and howl as their way of communicating, which is something you do not see in this movie.
Corrected entry: Towards the end of the movie, when they are flying a helicopter, they are flying a helicopter from the Norwegian company AirLift, registered LN-OMB, very unlikely to have a Norwegian helicopter in New Zealand. Also, the boat they land on is named "Polarsyssel", a Norwegian name, and signs onboard are in Norwegian.KaiGywer
Corrected entry: Throughout the movie the sound from the yellow DeHavilland Beaver airplane is that of a piston engine. The aircraft in the movie was a turboprop. A deliberate foley decision to make the plane sound more authentic, but a mistake nevertheless.
Corrected entry: When the dogs break off their chains and run away, it shows seven dogs running, but Maya and Old Jack are still back at the chain, so there should only have been six.
Corrected entry: The dogs are on their own for 15 days before even trying to break free from the chains. Even if they didn't die of starvation before then, they shouldn't have enough strength left to break through thick chains.
Corrected entry: In the opening scene, the dogs are shown in pairs, attached by a leash to the main line. The dogs on the right are supposed to be on the right of the main line, with their leashes attached at the left. The dogs on the left are supposed to be on the left of the main line, with their leashes attached on the right. All the dogs are lined up correctly in their pairs, except for one (he's on the right of the main line). Then, the next time they cut back to the group, he has miraculously switched to the other side where he was supposed to be.
Corrected entry: The Antarctic winter should make it nighttime all the time, yet the days run a normal day-night cycle.
