Corrected entry: Shortly before Stamper detonates the nuke we see a computer screen at NASA which shows the asteroid nearly at "Zero Barrier". Only 1 minute later, the screen is visible a second time and the two halves of the asteroid are already beyond the tangent where it would have hit earth on a straight flight. Earlier in the movie it is said that it'd take the asteroid about 3 hours and 57 minutes to get from zero barrier to hit earth. So it's impossible for the two halves to be beyond that line. (02:12:45)
Corrected entry: At the beginning when the small asteroid fragments destroy the satellite and kill the astronaut you can see that the pieces fall down even though they should be in zero G.
Corrected entry: In the film, there was a reference to a "French space agency." Unfortunately, there's no such thing, and the closest is the European Space Agency which has its headquarters in Paris.
Corrected entry: When we're first shown Harry's rig, after he's golfing on Greenpeace, his assistant tells him he "just found out something interesting". But, you can obviously see that he got that information from a written report he holds in his hands. That report was in his hands before Harry was golfing. You would assume that he'd report this important matter immediately to Harry, but he waits until Harry's done golfing on Greenpeace's head.
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 movie they show people around the world praying. They show a shot of Taj Mahal in India and hundreds sitting around praying. Oops, Taj Mahal is not a place of worship, it's a tomb.
Corrected entry: One of the things the creators of the movie did not think out is the issue of the asteroid's gravity. There are several problems with that. It is stated that the asteroid is the size of Texas. Even if we assumed it to have had 1000 miles of diameter (a really huge asteroid) and the same density as Earth it would have gravity of about 12% of Earth's gravity. In the movie it can be seen (even though stated otherwise) that the teams operate under earth-like gravity - tools, piping elements, debris all fall down with quite an acceleration. Also the astronauts move about very conveniently - much more easily than would for example on the Moon. On the other hand if we assumed that the asteroid had much higher density, which allowed it to had significant gravity, a near passing (a couple of hundred kilometers) of such a massive body alone would probably wipe out humanity just as efficiently as a direct hit. Even if we assumed that the asteroid's diameter was only 500 miles and its density was about the density of the Moon, the near passing of its two halves would wreak havoc on Earth as the influence of their gravity on, for example, ocean tides, would be up to 20 times bigger than Moon's
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.
