Factual error: The gold bars that the crew finds must be some new type of lightweight gold. There's no way that Julianna could stuff a gold bar in her back pocket and then pull it out and toss it on the table and Greer simply tosses it back and forth like it was plastic. A gold bar weighs around 27 pounds, you definitely wouldn't be tossing it around. (00:42:05 - 00:47:50)
Revealing mistake: When the crew are getting ready to load up the gold, one of the crew slams the crate lid making the gold bars "move".
Continuity mistake: When Epps first walks into Katie's cabin, there is a straw hat underneath a suitcase on top of the clothes rack. Yet when Epps gets up again after looking at the dress, the hat is now on top of the suitcase without her having moved it. (00:53:40)
Factual error: During the scenes where Santos is working on the main engines, he is actually working on a generator. A tug of that size would have a set of much larger engines with reduction gears (transmission), or be hooked up to large electical power plant to provide propulsion. (00:30:00)
Deliberate mistake: When the passengers are cut by the wire while dancing, some of the clothing on the torsos defies gravity. A man's coat tails and pants fall but a woman's dress stays put when nothing would have held it from falling from her lower half in the same way. (00:04:00 - 00:05:10)
Continuity mistake: When the demon meets the crew in a bar and asks them to find the lost ship he saw from the air, notice the beer bottles on the table; they keep changing from full to half full to full again, mainly the foam at the top. (00:07:55)
Visible crew/equipment: When the tug leaves the harbour in search of the (ghost) ship you can see the waves of the ship from which the scene is being filmed. (00:10:30)
Revealing mistake: In the beginning of the movie where the line cuts the dancers in half, blood is visible on the dress of one of the dancers before the line cuts her. This is best viewed in slow motion on the DVD. (00:04:00)
Factual error: There were absolutely no signs of ice or frost in any scenes while they were in the Bering Strait. (00:14:50)
Deliberate mistake: If the captain is bending over the girl to protect her and the line is at about mouth height for him, the line couldn't have gone straight through his mouth. Instead, it would have run from the back of his lower jaw up and horizontally to his left eye. (00:05:00)
Continuity mistake: In the scene abord the Arctic Warrior, the engineer is in the engine room rebuilding the engine, and he gets oil squirted on his right cheek. A moment later, the oil has moved to his left lapel and shoulder. (00:30:15)
Visible crew/equipment: Julianna enters a large hall while exploring the ship by pushing two big glass doors open. Looking at Julianna coming in, you can see a movie-lightbar reflecting in the glass on the right. (00:30:45)
Plot hole: Ships only steer when moving 'through' the water, not while adrift (moving 'with' the water/current). So the whole idea of fixing the rudder to steer away from the rocks without any propulsion is nonsense.
