Audio problem: When the Russian space station is on fire, and the crews are running out, you can hear Harry say, "Where's the rest of the team?" but his lips don't move.

Factual error: Throughout the time span the crew was on the asteroid, no signs of any gravitational changes occured. In fact, the gravity was much like Earth's, even though that's scientifically impossible.

Continuity: When the astronaut Sharp comes to his senses and decides to disarm the bomb while it is counting down, the digital readout is just all wrong. Bruce Willis is talking to him and the time reads 40 seconds left. After a good 20 seconds of talking, he starts working on the bomb with a screwdriver and the time reads 35 seconds. Next time we see it, it reads 30 seconds, then when the cover that holds the timer is removed it looks like it reads 45 seconds.

Deliberate "mistake": In the scene where the bomb is going to be remote detonated, on the inside lid of the briefcase, the remote destruct warning says that upon activation, the warhead will detonate in T minus 10 minutes. When the countdown begins on the bomb however, it is only for 6 minutes.

Continuity: 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.

Continuity: The front of the space shuttle explodes twice. After we see it explode the first time after it first gets bombarded with projectiles, in the very next shot, we see the front half of the plane with two crew members floating around inside at which point we hear: "Houston!". Then the front part of the shuttle blows up again.

Factual error: Okay, we know the astronauts can walk around on the asteriod because they have those thrusters. So how is it, then, that the lady pilot can walk around the shuttle without anything to keep her on the ground? She should be bouncing around like the moon walkers.

Revealing: When Ben Affleck riddles the shuttle's fuselage with the bullets from armadillo's gatling and then rams it to get outside, it can be seen that the side wall of the ship is paper thin. Now, I know titanium is a sturdy stuff but don't believe such a flimsy construction would be enough to stand the ordeal of a space flight with gravity loads during the start, escaping/entering the atmosphere and pressure difference in the vacuum of space.

Continuity: When they are boarding the shuttles, Harry and AJ have a brief chat and they get onto to bridge last. But somehow Harry manages to get in front of Rockhound and Max, and AJ manages to get in front of Oscar and Bear.

Continuity: After Harry catches AJ in bed with Grace, AJ runs out of the room. Cut to the next camera angle taken from outside as AJ leaves - and he has a pair of boots tied together around his neck. They were not there in the previous shot.

Continuity: During the scene when AJ is yelling out for any other survivors in his crashed shuttle, we hear Lev calling "A.J.", but with no Russian accent. Then Lev gets his accent back when he says "I'm here."

Deliberate "mistake": Before the two shuttles dock to the MIR station, Lev initiates a rotation to simulate gravity. The shuttles then dock with their side hatch pointing to the anchorage. As the gravity is pointing away from the centre of revolution and the station is revolving around its main corridor, the gravity would push the astronauts back in to the shuttle and not towards the floor of the gangways leading to the shuttle or towards the floor of the shuttle. Also, the artificial gravity would be reduced to almost nothing at the main corridor. But here the artificial gravity somehow points down in every part of the station, and appears to work equally well throughout the station.

Factual error: When drilling you have to remove the debris. This is usually done with some sort of liquid as an agent and supporting machinery. As the asteroid has some gravity the debris won't just flow into space. No machinery/liquid to be found anywhere.

Audio problem: When Freedom shuttle is being destroyed by the asteroid field, you can hear Harry say, "Sharp, what the hell is that? Is that the Independence?" but you can tell by Bruce Willis' mouth that he isn't saying any of those words.

Continuity: As Harry's crew is about to start drilling, Rockhound analyzes the surface. The drilling head is already bellow the asteroids surface. When the camera pans back to Rockhound the drill head can still be seen slowly turning on the upper right corner.

Factual error: It's explained in detail how the impact will cause a horrible freak tide, what it will do, and that one half of mankind will die in the nuclear winter. That´s absolutely irrelevant. The asteroid is "as big as Texas," that means several hundred of miles. Such an impact is called ELE (Extinction Level Event). A bigger part of the Pacific Ocean would evaporate immediately, so no matter if a wave or not. The earth would become "sterilized." So no lifeform will live long enough to die in a winter. (So it is nonsensical to compare that impact with the event 65 million years ago. It's much different.)

Factual error: When Oscar Choi is talking to A.J. about "Star Wars," A.J. is measuring something with a dial indicator, but he is holding it like a micrometer. A dial indicator needs to be fixed to something to measure how far the arm moves from your work piece.

Continuity: When Grace throws down Thurman because of frustration, she first grabs him by the back, but in the next shot he's facing upwards.

Plot hole: When the first shuttle has crashed, you can see that one of the characters (I think it was Liv Tyler's fiancé) has torn gloves. In space it is about -260 degrees celcius (don't know how many degrees farenheit) and that is pretty damn cold. He would lose his fingers and could even die.

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.
