Other mistake: When the huge alien ship settles over the White House there is an exterior wideshot of the grounds. At the bottom of this shot it's funny how there are many tourists - adults and children, just milling around in front of the gate and across the street with a van driving along between the two sides, and not one has any sort of reaction to the alien ship. This real shot of the White House (some shots had smaller-scale models) had the CG ship edited in during post production. (Visible on fullscreen DVD.)

Other mistake: When they're shooting the nuclear-bomb at the space craft for the first time (when it fails due to the shield on the alien space craft), you see that the airplane shooting the missile is breaking off to the left just after it's fired the missile. On the radar a few seconds later you see the airplane breaking off to the right. As if the radar displayed a mirrored view.
Other mistake: In the scene immediately after Jasmine, her son, and their dog escape the fireball in the utility closet, they emerge from the wreckage to find everything destroyed. But in the background there are two palm trees still standing, with leaves and branches still intact. Isn't it logical that a huge fireball such as that would at the very least burn the leaves off the tree?
Other mistake: When we see the Russian picture of the map where the UFOs are going in their country, the Cyrillic for Petrograd is incorrect as there is a Western lower case "r" in the city's name. The small "r" is close in appearance to the Cyrillic "g" which has a straight line (east to west)at the top of the letter instead of the curved line that we associate with our lower case "r".
