Continuity mistake: 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. (00:12:15)
Continuity mistake: When Harry goes into A.J.'s room, he gets mad and sticks the end of the golf club at A.J.'s throat, with the tip of the club to the right. The next scene, the tip of the club is facing to the left. (00:13:30)
Continuity mistake: When AJ bumps into Bear his shirt is very dirty on his right side, but as he runs up the stairs it is much cleaner and has a sweat mark around the neck line. Next shot on the tower and the sweat is not in the same pattern. After he slides down the cable the dirt is in a different pattern again. (00:14:10 - 00:15:00)
Continuity mistake: When the military come to get Harry from the rig, you see the shot going between the two. In three shots, Harry has a large speck of oil on his nose but on the fourth it has disappeared. (00:21:20)
Continuity mistake: 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. (00:51:00)
Continuity mistake: There are two crews boarding their spacecraft, called "Freedom" and "Independence." They are mounting a ramp and when on top, there is a crew member who directs the two different crews toward their ship: "Independence on the left, Freedom on the right." We even see the ships (in their initial launch phases) right next to each other - you can see one right next to the other as they launch. Then, once they're airborne, we see a long shot of the two bright engines, miles apart. (01:03:35 - 01:06:25)
Continuity mistake: The montages around the world show a boy listening to a transistor radio. In order to make it look truly Americana the boy has an old-fashioned earphone in one ear but continues to hold the transistor radio up to his ear as though the speaker were working in addition to the headphone. (01:03:40)
Continuity mistake: 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. (01:32:20)
Continuity mistake: 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 Air Force Sergeants takes the terminal. In the background, you can see the clock again but the time on it is at six hours and 49 minutes. (01:37:00 - 01:42:50)
Continuity mistake: 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. (01:44:35)
Continuity mistake: When Grace throws down Thurman because of frustration, she first grabs him by the back, but in the next shot he's facing upwards. (01:55:25)
Continuity mistake: Just after Harry says "prepare the world for bad news," air raid sirens start. There's a panning down shot of some air raid speakers next to a Coca-Cola ad, with a truck parked in front of it. The angle then changes to a shot down the street (same street, same speakers, same Coca-Cola ad), except the truck isn't in front of the ad any more. (01:56:10)
Continuity mistake: 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 mistake: 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.
Continuity mistake: Even though the second shuttle takes off later then the first, they are neck and neck when they clear the atmosphere.
