Continuity mistake: In the car chase scene, Mason is driving the stolen Hummer and he hits a meter maid truck sending it flying into a telephone pole and blowing it up. They slow down the film a little here and show us this hit from several different angles including from above. When they slow down the film you can see that the Hummer is turned sideways in the impact but in the next frame it drives off as if it had just tapped the meter truck and not slammed into it as shown.
Continuity mistake: At the start of the movie when Goodspeed and Marvin Isherwood are in the FBI lab trying to diffuse the gas bomb, when Goodspeed first walked into the chamber he stated his name, etc. he said that the time was 9:00am. However in the background you can see a clock that says the time is around 4:15.
General Hummel: Do you know who I am? Did they tell you why I am doing this? Why I am out here? Or are they using you like they did everyobdy else?
John Mason: All I know is that you were big in Vietnam. I saw the highlights on television.
General Hummel: Then you probably have got no fucking idea what it means to lead some of the finest gentlemen on God's earth into combat, and then watch their memories get betrayed by their own damn government.
John Mason: I don't quite see how you can cherish the memory of the dead by killing another million. This is not combat, it's an act of lunacy, General Sir. Personally, I think you're a fucking idiot.
General Hummel: "The tree of liberty must be refreshed from time to time with the blood of patriotism." Thomas Jefferson.
John Mason: "Patriotism is a virtue of the vicious, " according to Oscar Wilde.
[Hummel knocks him to the ground.]
John Mason: Thank you for making my point.
