Errores

One of the dogs is named "Scooper" (mentioned several times in the movie). In the credits, he is listed as "Digger"

When Barb puts 'chapstick' on Ted's lips, she has a blue mitt on, which had been under her gloves. When she puts the glove back on, the mitt is gone.

The skunk disappears and reappears between shots in the car.

After Ted has rescued Jack, Nana and Demon switch places between shots.

When Ted is chased by the bear, the back of his jacket is red like the rest of it. When he is sliding through the trees on his back, you can periodically see the back of his jacket is solid black (probably a slicker material for sliding on the snow). When he rolls over onto his stomach before sliding out onto the lake, the back of his jacket is red again.

Barking is heard while the sled dogs are running, but in actually, sled dogs are silent when they run.

When Ted first meets the Siberian huskies, they attack him. Siberian huskies are very friendly dogs towards everyone, even a thief.

When the VW being pulled by the dogs passes the truck, the man inside waving his hand is not 'Cuba Gooding Jr'.

When Dr. Rupert Brooks is talking on the phone with Dr. Ted Brooks, his words don't match with the mouth movement.

In the scene where Ted is standing on a piece of "ice" that is sinking, the high shot shows the frame for the lifting platform supporting the piece of "ice" he is standing on is visible under the water. Approx 56 minute mark.

When Ted is in the car being pulled by the dogs, you can see a red flashing light reflection in the windscreen of the cameras 'recording' light.

VW Bug scene with a skunk, there are no skunks in Alaska. It would have been more accurate to have a porcupine.

Tolketna is actually spelled Talkeetna Alaska.
