Other mistake: 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. (01:46:40)
Factual error: It is not feasible for a flood to stop the flow of warm air for the northern hemisphere and make it as cold as it did in the movie. The air moves far too fast for anything to stop the flow of warm air in the northern hemisphere.
Continuity mistake: When Jack arrives in New York he's right next to the Statue of Liberty. When the camera pans abowe the Statue of Liberty, you can see that front of the Statue is in light, and it's back in shadow. In the next shot front of the Statue is in shadow, and back in light. (01:42:35)
Continuity mistake: When Jack and the other bloke are standing and ask where the library is, they take off their skis and sled, and run a few metres and look over a sand dune. The camera zooms out a fair bit, but the sled has disappeared. (01:43:05)
Character mistake: The news reporter says that people are fleeing in the wake of the storm, meaning after the storm, not before the storm, which is what she should have said.
Other mistake: When his dad arrives at the library, the opening is larger and the raft with the food is gone. Had they gone out to get it after the storm passed, the doors would not have been frozen shut so neatly.
Suggested correction: Jack and Jason entered the library through a broken window in the large room they were initially gathered in shortly after the tidal wave. The raft with the food on it probably froze during the big freeze, so they never left the room after the storm passed.
Other mistake: At the beginning of the film, where Jack falls into the crevice, he's got nothing in his hands. In the next shot, you see he's clinging to the side of the crevice with an ice pick that has mysteriously appeared in his right hand.
Suggested correction: He probably had it hanging from a belt or something seeing as where he is he probably has a tool belt of things just in case something like that happens. He probably just grabbed it from the side you couldn't see.
There was nothing resembling an ice pick hanging from his belt before he fell.
