Other mistake: When Connie is waiting for the President the first morning she is reading USA Today. On the back there is a weather map and it is blue and green, the colours for cold in USA Today. It was a hot July day! (00:06:15)
Other mistake: At the end, when Steven and David's ship is released from the clamp in the mothership and are leaving, Steven never puts on his seat belt. Surely from all the twists and turns, not to mention the little nuclear explosion, he would have been tossed around just a little. (02:10:30)
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 the alien spacecraft arrives at New York City, notice the shadow of the alien ship moving up the World Trade Center buildings, yet the sun is still shining on the water in front of the buildings.
Other mistake: When the President and the others arrive at Area 51, the sliding glass door to the laboratory that the staff member opens with his key and numerical key code opens before he finishes entering the code.
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".
Other mistake: When Jasmine is trying to kick open the door in the tunnel, the second 'N' in maintenance is backwards.
Other mistake: When David asks Major Mitchell if he can shoot the soda can, Major Mitchell has to ask a nearby sergeant for his sidearm, despite already having one on him when he shot the alien earlier.
Suggested correction: He probably shot his own gun empty or nearly empty, so he removed the magazine. They fired at least 10 shots at the alien, and he planted another 3 in it up close.
Other mistake: When the US Military is deploying a nuclear bomb against the alien attacker over Houston, you see them fire the nuke and then the B-2 breaks left, but on the screen you can see the B-2 breaking right.
