Mark Valley's character FBI Agent Mike Johanssen appeared in the showdown between Agent Hubbard and General Devereaux (behind General Deveraux). However, Agent Johanssen was killed in an earlier scene at the 1 Federal Plaza bombing.
At approx 1hr 31 Mins, Annette Bening (Elise Kraft / Sharon Bridger) is talking with Denzel Washington / Anthony Hubbard in a car. She has little or no visible makeup. A minute or so later in the same scene she has mascara, lipstick etc.
Hub's drink disappears and reappears several times when he is in the restaurant with Elsie.
The length of the cigarette Hubbard is holding changes while he's interrogating the suspect about the suitcase of money.
After the bus explosion, the blood on Hub's face disappears and reappears between shots.
Twice, General Devereaux refers to "the president invoking the War Powers Act." The WPA is not presidential authority for allow war or the use of the military (which comes from Congress), but it is in fact a rule passed by Congress in 1973 (after Vietnam) that severely limits a president's ability to unilaterally use military force without Congressional authorization.
A diesel powered bus backfires causing bystanders to drop to the ground and take cover. Unlike gasoline engines, diesel engines do not backfire, except during very serious mechanical engine failures.
When they arrived at the hijacked bus, Hub ordered Elise to be taken behind the perimeter. Instead, she was taken to the negotiating line beside Haddid.
The FBI or any kind of civilian law enforcement agency would not be the ones serving a warrant or arresting a General or a member of the military. It would be MPs (Military Police) from the US Army's Criminal Investigation Division that would issue the warrant and be sent to arrest the General and his men.
General Devereaux wears a Combat Infantryman badge with a star. To be eligible for this at this point in time, he would have to have fought in the Korean war as well as the Vietnam war or other Cold War era actions. Apart from being too young to have been in the Korean war, he has no service medals from this period.
When Hubbard is thrown off his balance and he falls to the ground, you can see that the pavement bends a little under him - a telltale sign that the pavement is not real.
As in many movies and TV shows, empty paper cups are used when the characters are supposedly drinking coffee. This is most noticeable when Frank Haddad places a cup of coffee on the desk for Tony Hubbard. It has a hollow, empty sound.
From 1:49:45 - Scene at Tariq Husseini's auto repair shop.The pipe-rails and wooden spacers used to move camera in the footage intact. (Mr. Denzel step at the end of the shot.)Here is a "dirty factory," so it's not noticeable. Maybe.
In the meeting at Capitol Hill, among General Devereaux's medal ribbons is a Silver Star with a V on it. The V ribbon device may be used on certain medals to denote valor or combat service, it should not be on a Silver Star because that medal is only awarded for valor in combat.
When Hub and the other FBI agents raid Tariq's chop shop in Redhook, a shotgun can be heard being cocked even though the agent holding it is taking his hand off it when the sound is heard.
During the press briefing, the general praises the FBI, and specifically Tony Hubbard. The name 'Tony' is heard, but the general's lips say Thomas.
Sheik Ahmed Bin Talal is shown the be abducted in Lebanon, and a desert is shown. Lebanon is the only Arab country without a desert.
The events of the film take place in 1998, 3 years after the detonation of an explosive-laden truck in Oklahoma City. While many federal buildings were already constructed and could not be set back from a thoroughfare by the 100 foot minimum to prevent or minimize future terrorist attacks, ALL had anti-ramming posts, pillars and planters installed.
The van shown in the film could not have penetrated these barriers and thus the explosion would have taken place OUTSIDE the building, rather than inside of the lobby. There would have been heavy damage to the structure; however its total collapse as shown in the film likely would not have occurred.
During martial law, civilian law is suspended and the military commander of the operation has unilateral power in creating and enforcing laws. Therefore Devereaux would not be subject to any legal repercussions.
At the strategy meeting, one of the participants cites Lincoln's suspension of Habeas Corpus in 1862. Another states that this act was declared unconstitutional by the Supreme Court and cites the case "Ex Parte Milligan." The actual case for this incident is "Ex Parte Merryman." The Milligan case involved the military trial of a civilian. The case determined that civilians cannot be tried in military courts, except under specific circumstances, which the Milligan case did not meet.
General Devereaux mentions the M16A1 assault rifle when he should have said the M16A2, since the M16A1 was an old rifle mostly phased out of U.S. service by 1998.
At one point, the news refers to Hubbard as spokesman for the FBI, when he is in fact a special agent in charge.
