Factual error: When Jack is showing Professor Rapson projections of the world, with the coloured storms, he first shows a quick picture of Europe. Greece is not visible on this map, you may have to look carefully.

Continuity: At the beginning of the film, when Dennis Quaid is running from the cabin to help his friend, in the far shot, you can see him run onto the ice, but in the following shot, he is on the stairs.

Visible crew/equipment: When the janitor is approaching the door you can see a shadow of a man, which isn't the janitor's, in the background holding something that appears to be a microphone.

Factual error: The old Sky News logo is used in the film, as shown in a broadcast.

Continuity: When on the plane and there's the major turbulence Sam's hair flops over his forehead.Then he looks at the wing and there is no hair on his forehead but in the next shot of him his hair is back messed up.

Continuity: When the man asks Jack "Why for the love of God would you aggravate the Vice President?", he has both his hands up. When it cuts his hands are down.

Continuity: When Jack and Lucy are talking about Sam failing class on the phone and Lucy says "I don't have time to talk about this right now", it shows Sam eating and a milk pack with its opening pointing left. When it cuts the opening is pointing right.

Continuity: When the tidal wave is about to hit Manhattan, Sam and his two friends are walking up the stairs, and the black friend's hood is over his head, but in the following shot it is no longer over his head.

Continuity: Just after Terry looks at the boys on the screen with Simon, in the overhead shot of Manhattan traffic, the homeless guy in the middle of the traffic is walking towards a black car with a police car beside it. But in the following closeup he has passed the cop car and is now at the bumper of the black car. (Zoom in is required).

Continuity: The image from the space station that is sent to Tamlyn has no vortex. However when she sees the images on her screen there is a vortex about 50 miles in diameter.

Other: During the tornadoes in LA there is a large sign that slams into the news anchor. The speed and angle of the sign would throw the anchorman at least towards the van that it goes over. Even if his body did hit the ground with the sign flat on top of him, his body would have moved towards the van if not slid far beyond it.

Factual error: When we see a TV report saying how England is affected by the storm we see a shot of a street with hanging yellow traffic lights. England doesn't have yellow traffic lights, we have black ones. It's obviously footage of a storm in the United States.

Continuity: When Sam, Laura and the black student enter J.D.'s hotel room, Laura asks, "You live here?" and J.D. looks at Laura then puts his coat down, but in the next shot his back is to her and is putting his coat down again.

Continuity: Near the start, when it cuts to a street in Japan, a large hailstone hits the policeman's car. When it hits, the wipers just brush it away and keep working, but in the following shot when the policeman looks back at his vehicle, the hailstone is still there and the wipers are no longer working.

Revealing: When the tornadoes are hitting Los Angeles you hear a woman say,'Is anyone hurt?' The angle is high and you can see the Capitol Records building, the tornado and the helicopter. If you look very closely at the bottom right you see lots of cars on the road driving like mad and one of them drives under a large truck trailer, betraying that they are CG cars.

Continuity: In the scene where Sam smashes the vending machine in the library, you see him first take out about three items from it, and then in the next shot you see him holding two items, but when he throws them onto the table there are about a dozen packets of sweets and crisps.

Continuity: In the scene when Terry Rapson is looking at his grandson's drawing, Simon comes into the room and puts a cup of tea on the desk. In the first two shots you see that the cup is in the same position where the handle is facing exactly towards the camera, but in the third shot, it has changed position, and the handle is now pointing to the left.

Factual error: Given that the entire premise of the movie revolves around the melting of the ice caps and the disruption this causes, including a rise in sea-levels, and that at then end of the movie most of the Northern Hemisphere outside the tropics is covered by an enormously enlarged ice cap the sea-level should have lowered significantly enough for the shape of the land masses to appear different from space.

Factual error: When the students arrive in New York, you can see the luggage tag on Laura's bag. It lists JFK below DCA. This means the bag would have flown from somewhere to John F. Kennedy airport in New York, and then connected onto another flight going to Reagan National in Washington DC. Since New York is their final destination, JFK should have been the top airport code, even if they had connected through somewhere else.

Other: In the scene where the first storm appears, you see little windmills spin and trees affected by this wind. However, the hair of the old man walking out of his house (in the same shot) is undisturbed.
