When Jerry and Mindo are sitting at the table in Mindo's cabin, there are plates on the place mats in front of them while Mindo is looking at the photo album. The scene then shifts to Mindo, then back to Jerry where the plates are now missing.
When the dogs offer the injured Maya a seagull, the amount of
snow on her head changes from shot to shot, then disappears completely.
When Jerry is doing introductions of the dogs at the beginning of the expedition both Malamutes are on the right side of the main line. And in the next shot Buck is on the left of the main line and Shadow on the right.
At the celebration evening for the finding of the meteor, Jerry is served a glass of beer without collar. When he turns around and walks to the table, the glass suddenly has a collar.
At 00:06:29, Cooper get a stick in his mouth. At 00:06:30, he takes it off. At 00:06:31, he takes it off again.
At the beginning of the movie (when it is January) it is pitch black out for all the night scenes. That close to the South Pole the sun would be above the horizon for at least twenty-three hours per day, and the sky would still be quite bright for the other hour. Also, just before the dogs are rescued, (July time frame) shadows are seen indicating that the sun is pretty much directly overhead. During this time of year, the sun is only above the horizon for about an hour per day, and would never be anywhere near that high in the sky.
The Otter aircraft used in the flying scenes has been converted to a turbine (jet prop) engine, as visually confirmed by the ultra-long nose and the 4 bladed paddle propeller. The movie engine sound effects are those of a standard reciprocating (gasoline) engine, which would have a very short round nose and a 3 blade prop.
When Max sees the seagull for the first time, he finally breaks loose of the chain and chases after it. The other dogs run off with him and if you look close enough, there are 7 dogs that run together after the bird. However, there should be 6 since Maya and Old Jack are still at the base.
In multiple outdoor scenes, characters don't exhale condensed vapor when talking, which reveals that those scenes were shot in a warm green-screen studio.
When Jerry returns to chain where are the dogs were left, he notices one link broken. Then he gives the chain a quick jerk. The chain appears to be buried only a few inches deep. After 176 days and a severe storm, the chain would be buried much deeper.
Story takes place in the early 1990s. However, when Jerry is walking down the street in Washington D.C., several present-day cars can be seen driving around.
The movie is set in 1993, but when the characters are drinking Fresca, the bottles have white labels. Fresca did not adopt a white label until 2005.
The Otter airplane is obviously powered by a turbine engine with an elongated nose and a turbine exhaust pipe, but the sound is that of a piston engine.
At the point where one of the twins is offering the female leader a
dead seagull, he looks towards screen left and backs up. At the same time, if you follow his gaze, the trainer's hand can be seen for an instant motioning towards him.
After the helicopter lands on the icebreaker, the ship heads toward Antarctica and gets stuck in the ice. In one of the aerial shots of the boat, the helicopter is clearly not on the ship - probably because it is being used to take the aerial shots of the boat stuck in the ice.
When Jerry is in Pasadena, there is a tree growing outside of Dr. McClaren's house that is heavily covered in moss. Hardly vegetation typical of California, but very much common to Vancouver, where the movie was filmed.
The full moon over Antarctica is oriented with its north pole up, as it appears to observers in the northern hemisphere.
The bar is supposedly located in Christchurch, New Zealand, however, it is obviously located in Canada. The beer taps behind the bar show Alexander Keith's India Pale Ale (brewed in Nova Scotia) and Kokanee (brewed in BC) - two VERY Canadian brands.
The Norwegian vessel "Polarsyssel" used in the movie, was used by the government on Svalbared, north of Norway, between 1988 and 2002, so it could not have been in Antarctica in 1993. The helicopter they used was registered in Norway (LN).
