Continuity mistake: In the scene where the postman gallops by the country house full blast and then comes back to pick up the letter from the boy's hand, you hear hoof sounds for long enough to take him hundreds of metres away, while the camera is on the boy. But when he is actually shown stopping to turn his horse around he has only come as far as the corner of the premises, maybe 20 meters away. (01:53:05 - 01:54:05)
Continuity mistake: The downtown skyline keeps changing during the scenes where an asteroid segment is threatening Kansas City.
Continuity mistake: When Ullie Birve's character is taken from Earth near the end of the film, her clothes fall to the ground. In the moments just prior, she is shown fading in and out, but so do her clothes.
Continuity mistake: In the scene where Asuka is fighting against the JSDF aircraft, her umbilical cable is severed and she ejects the umbilical plug. She then expands her AT field and the plug is connected in her back again. In the next shot, it isn't there.
Continuity mistake: The topless blonde assassin knocked out by Wayne appears dead a few scenes later over a puddle of her blood but with no visible wound. She is trying to get up when Marina appears to pick up a gun and taunt Wayne who's dealing with the other nude assassin, only to still be lying down a cut later. Marina could have shot her dead at this point, but doesn't and therefore the blonde's death makes no sense. The assassins' corpses are also lying in different positions than before.
