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.
Revealing mistake: When Mason is having his hair cut, after finishing up, he is talking to Womack and turns his back on him. If you look at the back of Mason's neck, it is clear that he's not just been freshly shorn; there are whorls of hair just above his collar. (Either that, or the barber was terrible at his job).
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. (00:08:35)
Continuity mistake: In the chase scene, Cage is in a real Ferrari F-355 at some points, but the car switches to a replica 'kit car' in various scenes. When it is crushed, you can see the fibreglass kit car body pop off to reveal the Pontiac Fiero guts. I heard our friends from Maranello were not impressed.
Continuity mistake: During the chase scene, just before the Ferrari is destroyed by the trolley, you see Cage dive out of the car and a rear view of the trolley hitting the car. In this shot, you see the complete rear end of the Ferrari, with a blue pickup next to it. In the very next shot, the Ferrari is getting sandwiched between the trolley and the pickup.
Continuity mistake: When Hummel sends patrols in search of the SEAL Team, the Marine with the messed up hair-cut(the spanish guy with the "bun" on his head) stays behind and is watching the monitors. There are shots of him watching the monitors and saying "something's not right." Yet there are also shots of the Marines on the patrols, and he is one of them. The it cuts back to the monitor and he is the one that alerts the Marines the shower room has been breached.
Continuity mistake: As the seal team are about to enter the shower room, we see them cutting the sensor beam using two mirrors. In the next shot we see the seal removing both of the mirrors from the drain ready for incursion. In the shot in which they pull back the drain, one of the mirrors is still there.Scrappy
Factual error: Atropine is on two occasions in the movie stated to offer some kind of protection against corrosive gasses. First, against the nerve agent/gas Goodspeed encounters in the beginning of the movie, which is corrosive enough to eat through a protective suit. Secondly, near the end of the movie against the cloud of VX gas; here Goodspeed injects Atropine into his heart and survives without a scratch even though it is stated that VX will melt your skin. While Atropine is used to counter the effect of nerve agents, Atropine (or any other drug invented by man) wouldn't do anything against a gas that can eat through a protective suit or dissolve skin. In this case the muscle contractions created by the nerve agent would be the least of your worries.Andreas[DK]
Continuity mistake: In the scene where Nicholas Cage and Sean Connery are held prisoners in the cells in Alcatraz, Connery has made a rope and swings it for the first time, and the handle for one cell is brought down, opening the door of the cell beside Connery. However, when he tries for the second time and gets the correct handle, the handle used previously is back in its place, and not horizontal as it should have been.
Continuity mistake: As Mason escapes from the hotel, we see him running down the escalators to the kitchen. On his way down, he pushed over two waiters who fall, the waiter on our left falls onto his back on the close up shot, but as the shot changes to the wide shot we see him falling again onto his front.Scrappy
Factual error: VX is a real nerve agent and it is considered one of the most deadly. But VX does not melt away your skin. In reality, VX gas causes involuntary muscle contractions that result in death by asphyxiation. Apparently this wasn't dramatic enough for Hollywood. It's also amber, not green.Andreas[DK]
