Factual error: The volcanic lava in this movie moves incredibly fast in the subway line. This is not only inaccurate, but also ridiculous and unnecessary. Volcanic lava can possibly move faster when in a concealed area that insulates it, but insulated lava cannot move that fast.
Continuity mistake: When David tells Kevin and Jennifer about Bean staying at their house and he says "Let's say there is a chart of the most intelligent people...", you can see a blue pillow on the couch which Kevin and Jennifer are sitting on.

Visible crew/equipment: In the scene where Lily and Dan are doing it in the car, you can see someone sitting in the front seat in the car rocking it.

Continuity mistake: Towards the end of the movie, when all three are crawling through the Lincoln Tunnel, they are almost waist deep in water. Yet, the Secret Service lady's jeans change from dry to wet and back again. The same when she is chased back through the tunnel, her and the Secret Service guy's trousers are dry.
Revealing mistake: During the ending sequence, just as J.T. Walsh is pushing the truck on the bridge, there is a shot looking at the front of the semi and you can see that it is not J.T. Walsh driving. The stunt man is noticeably heavier than J.T. is, and his hair is messier.
