Corrected entry: The entire scene where Will Smith and his girlfriend first see the spaceship is pretty ridiculous. First, Will goes out to get the paper, but instead of taking it back in the house, he opens it up and starts reading it - in the yard. Then Jasmine comes out (conveniently neglecting to notice the spaceship that's directly in her line of vision) and offers him a cup of coffee - in the yard. Were they planning to spend the rest of the morning standing in the front yard? (00:25:20)
Corrected entry: Why did the aliens take up position over the First Interstate building in downtown L.A.? This is not the centre of L.A., nor is it a pivotal role in the functioning of the city, like the White House. Come to think of it, neither is The Empire State Building in New York City. These don't sound like very practical tactical positions. They must really hate bankers. (00:46:30)
Corrected entry: After they had brought the First Lady into Area 51, the doctor said to the President something like:"Your wife has internal bleeding, there is nothing we can do for her, she will die soon." The helicopter crash which caused that trauma was at least 12 hours ago, nobody could survive that time course with severe internal bleeding! Why couldn't those guys at Area 51 operate on her, and how the hell did they even know that she has internal bleeding severe enough to die from? (01:32:00)
Corrected entry: In the one of the final sequences when it is showing the ships being brought down all over the world, it shows one crashing over the pyramids, and one crashing somewhere near Sydney Harbour, as well as the one which is crashing at Area 51 in America. In all of these scenes it is daylight, which is near impossible given that these locations are fairly evenly spread across the world, and it has to be dark somewhere.
Corrected entry: A shot near the end of the film shows a burning alien ship over Sydney. Given the speed at which the aliens destroy major world cities, Sydney should have been leveled long ago.
Corrected entry: When the alien is brought into the containment lab of Area 51, we see all sorts of high-tech monitors set up and doctors running around checking everything works and everything is prepped and ready for the alien. So why is it, after all this work, they forget to administer some form of anaesthetic to the alien knowing that not only is it merely unconscious from a punch to the head but it has a nasty temperament towards mankind?
Corrected entry: When Jasmine is in the tunnel during the attack and sees a large fireball coming at her in the rearview mirror, there are people running and lots of destruction but her little boy is sitting in the back seat not even concerned with what's going on.
Corrected entry: When Russell is in his trailer listening to the radio (right before the youngest boy barfs), the announcer says (paraphrase) "Reports indicate that Los Angeles, Washington D.C. and New York have been completely destroyed..." Russell starts to say 'Good God.' just at the mentioning of the cities' names. Shouldn't the actor wait until the news comes until he is surprised?
Corrected entry: Tell me this: why can Jeff Goldblum drive straight to the White House without hitting traffic? They drive down a motorway while everyone is trying to get out of the city, yet everybody obeys the law and stays on the proper side of the road. What good citizens. They might die but they still obey the law.
Corrected entry: In the scene where the B-2 Bombers are going to nuke the ships, you can see the Houston citylights below them. Why is there intense citylight in a devastated city?
Corrected entry: The planetary saucers in the movie are 15 miles in diameter, and are 2.5 miles in height. Assuming that 9/10 of the ships are air or lighter then air gases, and that the ships' walls are made of a metal with the density of water (this is a very generous estimate), then each ship would weigh 100 billion tons! No matter what source of flight used, these ships would create a pressure of 30 atmospheres on anything below it. Most buildings would crumble under 5 atmospheres, and our bodies would flatten like pancakes long before that.
Corrected entry: When the President "fires" his Secretary of Defense, SecDef protests by saying "you can't do that!" He, in fact, is right. The SecDef would have to be impeached by Congress.
