Corrected entry: During the scene where General Devereaux is giving his speech after Marshal Law has been started, the camera is showing different parts of the city during Devereaux's speech. Despite that the speech starts and ends during daylight hours, one of the shots shows Devereaux giving the speech on the JumboTron in Times Square at night.
Corrected entry: In the scene where the government leaders are discussing whether or not to deploy the Army to New York, Bruce Willis, as the general, rattles off an assortment of military units and vehicles available. He ends by saying something about every soldier carrying an M-16 A-1 assault rifle. The active Army has not used the A-1 for many years, they switched to the A-2 in the late 80's or early 90's. A general should know this.
Corrected entry: When Samir tells Annette Benning about his brother who blew himself up in an Israeli movie theater, he said the brother was told by a sheik that suicide bombers get "70 virgins in paradise". According to Islamic hadiths (not the Quran directly) the number of virgins awarded those who die fighting for Islam is 72. An Islamic fundamentalist leader like the terrorist sheik would know this fact well.
