Other mistake: After Molly crashes the taxi, she is standing outside in the bitter cold. Yet you never see her breath (vapor) when she is speaking or when she is huffing and puffing when confronted by the wolf.
Other mistake: When James and Samantha are in the cabin, James asks for a phone. Samantha points him towards the kitchen and then unplugs the phone in the living room. He then says the phone is dead, but unplugging one phone wouldn't render all the other phones inoperable.
Revealing mistake: When the cab skids off the road and down the hill you can see that it never actually hits the tree - it is yanked back with about a decimeter left to go before it would hit.
Continuity mistake: Rocks destroys Daphne's house, and attempts to make it up to her by fixing her broken food bowl. He pushes the two pieces together with his nose, and they are not flush. In the next shot, he puts his head up and you can see that it's a full bowl without any cracks.
Factual error: The movie is set in New York, and Rocks is fighting wolves. Wolves are no longer found in New York.
