Other: Towards the beginning of the movie, one of the characters starts the ignition on his truck. If you look carefully, he turns the key the wrong way.

Continuity: When Sam and the other two students are on the big ship, Sam goes outside so that the wolves will chase him, locks the door, then climbs the ladder to a door where the students are. The black student is startled and turns around with a metal scoop to his right getting ready to sling it, but in the following shot the scoop is over his left shoulder.

Other: Near the end of the movie, in New York, once the storm has cleared, ships seem to be pointing out of the ice at all angles. For a while before the water froze over, the ships would've had enough time to either level out or sink if they had been ruptured in some way. Also, there is no way they could be touching the floor of the harbour, seeing as how the water not only rose, but it was already deep enough for ships to pass without difficulty.

Factual error: When the Scottish scientist calls Hall, he tells him that the freezing temperature of fuel is -150° Fahrenheit. This isn't true, Jet A1, which is the type of fuel in such kind of choppers freezes at -52.6° Fahrenheit. The scientist says that they had to look it up, so the should have the correct figures and as this figure is quite important to estimate the temperature in the eye of the storm, he wouldn't mix it up.
