Continuity: 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.

Continuity: When Harry goes into A.J.'s room, he gets mad and sticks the end of a putter golf club at A.J.'s throat. The next scene the club changes and is not a putter anymore.

Continuity: When Harry is golfing off of the oil rig, the holes on the golf ball are spaced about a yard away. In the next shot, before he hits it, the holes are right together. It also goes from saying just "Srixon" to "3 Srixon," then the lettering gets angled, then he finally hits it.

Factual error: 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.

Continuity: When the team meets the flight crews for the shuttles, there are two munitions specialists - Gruber and another astronaut. We see this other astronaut board the shuttle, then he's never seen again, not even his body.

Factual error: 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 move are known as "rock bits" and will not cut through metal. There are special bits known as "milling" bits to do that.
