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: It took approximately 18 hours from the time Harry and Grace left the oil rig until they decided to help save the Earth. How did his entire crew have time to become scattered across the US? AJ even had time to start his own oil company.
Corrected entry: In the scene of the asteroid being split by the nuclear explosion we see the blast from Earth's point of view in settings which are on opposite sides of the world. This is impossible since the asteroid is coming from one direction and only half the planet would be able to see it.
Corrected entry: When the two teams visit the space-station, NASA tracks them each through their green "blips" from their locaters. When A.J. and the Russian were locked in the fuel pod, the control team at NASA could see their green "blips" on their screen. The Russian didn't make the trip, why would he have a locater on him?
Corrected entry: En route to the asteroid the shuttles are slingshotted around the moon. Due to the speed and strong curve they're making, the crew is experiencing about 12G. You see the crew screaming like hell and being very awake; in reality, they wouldn't be screaming as the G forces presses the air out of their lungs and it would be very hard to breath. Also, to keep conscious at such high G levels you need to tense all muscles in your lower body to keep more blood in the head, the crew are obviously too busy screaming to think about this. And lastly the crew would probably be unconscious anyway; 12G is a hell of a force and knocks out the most trained fighter pilots around.
Corrected entry: At the end of the movie when they are heading back to earth the astronauts are wearing space suits and the pilots are wearing flying clothes but when they touch down the astronauts are wearing orange uniforms and the pilots blue.
Corrected entry: At the beginning when the Chinese people arrive on Harry's rig, Harry says that Grace is going out with AJ due to a lack of choices because no one else is in her age bracket. However, after AJ proposes to Grace, Harry says that Oscar is 5 minutes older than Grace.
Corrected entry: Throughout the movie, the United States is making all the decisions about how to do things. This is most demonstrated when the President of the United States gives the order to remote detonate before the 800 ft. hole is dug. Why does the President get to decide and almost doom the whole planet? Shouldn't the UN make decisions like that?
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)
Corrected entry: In the scene where the asteroid is about to hit Paris, look closely at the clouds. They don't move. An asteroid coming in at that speed and force would blow the clouds away.
Corrected entry: If the movie was set in the summertime, why was the 6:30 pm launch done after sunset? Even if was AM, the sun would have still been up at 6:30
Corrected entry: In the scene where the Russian space station starts to collapse A.J and the Russian cosmonaut gets trapped in a room. In order to check that everyone has reached their respective ship Houston turns on a "personal radar" which lets them see everyone in the station in a 3d-model on screen. This is done through trackers in the Americans space-suits. Only problem is that the cosmonaut also shows up on radar and he, apart from already being there for a great period of time, definitely does not have an American space-suit with a tracker.
