Deliberate mistake: In the opening scenes just after the restaurant dialogue, as soon as the scene changes there is a quick cutscene which shows the screen zooming in on the Pentagon. If you look In the lower left corner, the text on screen gives the Pentagon location as being in Washington D.C. however, The Pentagon is located in Arlington, Virginia. (00:19:02)
Deliberate mistake: After David jumps off the roof of the Firebrand building, it is discovered that he had been wearing a parachute, but this parachute was never visible on him at any point previously in the scene. Even when he was on the roof and after jumping, the parachute was nowhere to be seen. The parachute was too big to have gone unnoticed. It would have been visible whenever the shot was behind him and the straps would have been seen whenever the camera was in front of him. (01:17:30)
