Factual error: After crashing on the asteroid, A.J. walks outside surveying the wreckage while debris is strewn out burning on the ground. This is wrong, as oxygen is needed to make something burn, and there is no oxygen in the asteroid.

Factual error: When a scene is showing people all over the world just before the shuttles take off, it is daylight everywhere. It would actually be dark or near dark in parts of the world.

Other: A.J. gets dirt on his face although he is covered by an astronaut's suit.

Continuity: When Harry is going to A.J's room, he bangs on the door with a golf club. You can see the white fan fall to the ground. Then when Harry walks in the fan is back on the ledge.

Continuity: At the end of the movie, after the asteroid explodes, we see Grace looking through the glass and there are reflections of NASA controllers cheering. The same shot was used earlier in the film to depict Grace looking upset at some bad news. The camera zoomed into the picture a bit, but you can still see one controller cheering.

Revealing: There's grass on the edge of the cliff when the Armadillo finally lands - look just under the Armadillo while the astronaut's pulling himself up the road. Considering this is an airless, waterless asteroid, it doesn't really fit...

Continuity: When they are in the shuttle trying to disarm the bomb, it is the pilot that is telling the munitions specialist, the guy that is supposed to know everything about the bomb, which wires to cut.

Continuity: The first meteor is a direct hit on a street vendor in NY where the dog is chewing on one of his Godzilla figurines. To start with he's chewing a small Godzilla, then it cuts to the vendor tugging on it, then it cuts back and its suddenly a much larger one.

Continuity: Even thought the second shuttle takes off later then the first, they are neck and neck when they clear the atmosphere.

Continuity: After Sharpe and Stamper have the argument on the asteroid, Truman says they need the radio back up. When he says this, you see the countdown clock for the asteroid which is at five hours and 12 minutes. A bit later in the film, after the nuke was shut down by a technician at NASA, one of the military officers takes the terminal. In the background, you can see the clock again but the time on it is at six hours and 49 minutes.

Continuity: When in the Russian space station, AJ is in a little pit fixing something. When we see him, he has a little snow hat. The next time he has nothing on. Then back again with the little hat.

Continuity: When A.J.'s Armadillo needs to break out of the space shuttle, the crew shoot up the walls of the hull of the ship. But then when they drive the Armadillo through the hull, the ship breaks apart at the seams rather than at the bullet holes.

Continuity: In the scene where they are discussing the plan to jump the armadillo, A.J. Frost's left ear goes from having a clear earpiece over it in profile, to having a yellow earplug in from the front.

Continuity: In the sequence where they are disarming the bomb. When the clock gets down to 00:24, the picture is reversed (the split second shot when they pull the clock out of the bomb). This one is better to go frame by frame on the DVD.

Other: The two ships that the astronauts and drillers are supposed to be new, military vessels that were top secret - and just happen to bear a resemblance to the actual NASA shuttle orbiter. But, when they are launched, on the wider shots it appears that the footage is just stock shots of the space shuttle taking off. It is only in the closer shots that they actually bother to show the fictional craft. (Additional Information: During the X-71 launch sequence, they used real Space Shuttle footage, and used computer graphics to stitch the image of the X-71 onto a shuttle rocket stack. However, at least once during the sequence, you could see they forgot or didn't bother to change the Shuttle to the X-71. They just left the video as it was, and you could clearly see that it was a real Shuttle, and not the X-71. )

Factual error: In the opening sequence, an asteroid headed for Earth, and are told that this was the "Dinosaur Killer" 65 million years ago. The narrator says that it exploded with the force of "10,000 nuclear weapons." If we assume the asteroid that impacted was nine miles across (a typical number used for the impactor) and moving at 10 miles per second (which is actually a minimum speed; it almost has to be traveling faster than that) the impact should release something like 80,000,000 megatons of energy. Even if we assume a 100 megaton bomb, which is comfortably larger than any nuclear ever detonated, that's 800,000 nuclear weapons.

Visible crew/equipment: When on the asteroid, Rockhound starts to play with the gun. To stop him Harry goes over and pushes him off and they both go flying through the air. Just before they hit the floor you can see the zip wire they flew across on.

Continuity: During the scene where AJ is playing with cookies on Grace's stomach on the last night before the launch, the car behind them alternately appears and disappears as well as moves around. Best example - wide shot shows them well behind the car, then in a shot of Grace her head's right by the tyre.

Revealing: When Bear is on the asteroid lifting the tubes to drop down the hole he is straining to lift them. Since there's minimal gravity on the asteroid, why is he straining?

Deliberate "mistake": In the New York Meteor Shower scene, most of the cars blow up without having been hit at all.
