Corrected entry: In the beginning of the movie, in the scene when the oil well "blows out," pipe starts flying into the air and oil shoots out everywhere. It does not happen like this. When an oil well "blows out" while drilling, the drilling fluid would be the first to come out, followed by the oil. Besides, the crew would shut the blow out 'preventers' long before the fluid would fly out as forceful as in the movie. Also the pipe would not fly out unless no preventive measures were taken. In a subsequent shot, they show one of the roughnecks turning a valve to shut the well in. In real life, the blow out preventers would have to be closed by actuating a hydraulic closure ram.
Corrected entry: The two ships that the astronauts and drillers use 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. )
Corrected entry: This movie makes the same mistake several others do about the effects of nuclear explosions. Without an atmosphere, you get a very hot fireball and some radiation. there is no air to create a pressure wave which would blow the asteroid apart. At the most, you have a melted center and maybe the asteroid would collapse on itself if it had enough gravity.sexxypeety
Corrected entry: Both teams have to drill an 800-foot hole in the asteroid (even though only one team made it to a drilling location). They are doing this in an area that the ground is mostly metal and they are using metal drill bits. The bits the drillers use in the movie are known as "rock bits" and will not cut through metal. There are special bits known as "milling" bits to do that.
Corrected entry: At the end of the movie there is a flyover by Air Force jets (the Thunderbirds possibly?). At the end of the flyover one jet peels off in what I believe is supposed to be the "missing man formation." However, the plane that leaves is the one in the back middle. This is incorrect, as it leaves an intact 5-plane V. Instead one of the planes to the side of the lead plane (on either side) should have left, leaving an unbalanced, "missing" formation.
Corrected entry: Just before A.J goes down the chute in the Russian space station to refuel the rockets, you can see an American flag behind him. Odd that an American flag would be on a Russian space station.
Corrected entry: In the scene where the first crew ship collides with the asteroid after being slung around the moon, the pilot is seen crashing into the window of the other ship without "space gear", untrue as we know oxygen does not exist in space, and the fact that there is no gravity would make the body implode not just go around like normal. That is why astronauts wear suits outside the ship, very carefully designed suits that allow for them to be in that environment.
Corrected entry: After the transmission blows on the asteroid causing Harry to be thrown about 15 feet away, in the very next shot when he is asking God for a little help, we can see that he is suddenly standing in front of the spinning drill bit head. How did he pick himself up and get back there so quickly?
Corrected entry: When AJ is down getting the liquid O2 and they have to evacuate, fire blows up the tunnel and engulfs him as he is climbing out, yet even though his face is uncovered, he is not burned.
Corrected entry: In the scene with A.J's Armadillo, you can clearly see the shadow of one of the cameras in the smoke behind them.
Corrected entry: During the opening titles after the asteroid hits earth, the fireball spreads out around the world and the camera angle shifts across about 10% of the earth's surface, and suddenly the fireball has progressed almost completely around the entire world. It wouldn't have happened anywhere near this quickly, and its appearance would have changed as its intensity diminished. (00:00:55)Bill McIntyre
