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: In the scene where Will Smith first notices the spacecraft, he is absolutely astounded by the sheer size of it. Yet his girlfriend, bringing him coffee, doesn't seem to notice it until she walks up to him and looks at his face to see what he is looking at. She didn't notice the 15 mile long UFO? It's not a really a mistake, just really crappy writing and acting.
Corrected entry: When in the area 51 base, a screen in the background shows a night vision view of a plane landing. Why is a Panavia Tornado fighter bomber landing in an American secret base, when they are flown in England, Germany and Italy?
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.
Corrected entry: The Secretary of Defense turns towards the President and gravely announces "We can expect the destruction of all major cities in 72 hours". Wow, I'm impressed. Either the US or Russia could accomplish that in less than half an hour. Incredibly advanced technology ain't what it used to be...
Corrected entry: In the mother ship Will and Jeff light up their two last cigars after transmitting the virus. On the ground contact is lost for "20 mins" - yet when they are picked up on the ground the cigars are still at full length and haven't burnt down a bit.
Corrected entry: The shape and size of the aliens isn't exactly humanoid, but, when Jeff and Will board the space ship the seats seem to be pretty well designed to accept a human body...
Trivia: According to the Director's commentary, Twentieth Century Fox Film Corporation did not want the film to be released under the title "Independence Day" to avoid legal complications (specifics weren't disclosed as to what the problems might be, but it's also why the abbreviation "ID4" was used). Roland Emmerich (director/writer) and Dean Devlin (writer) needed to justify the title, so they added the rousing bit right at the end of President Whitmore's speech at the hangar when he ends with, "The 4th of July will no longer be known as an American holiday...today we celebrate our Independence Day!"Super Grover
