Continuity mistake: Nick Cage is chasing Mason in the yellow Ferrari. The windshield breaks at least twice, but is perfect in the next shot. (00:45:55)
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: 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 movie when Mason is talking with his daughter in the park, his tie in one cut is tied differently then in another cut of the same scene. Look closely at the stripes.
Continuity mistake: During the Hummer chase scene, after the Hummer smashes into the truck with all the water jugs, you can see from a shot inside the Hummer that the windshield is cracked. For the rest of the chase, it isn't. (00:45:28)
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: Towards the end of the movie when Ed Harris gets shot watch him fall. He lands on a mat then a second later you see him being dragged by Nicolas Cage and the mat is gone.
Continuity mistake: The number of jets flying towards The Rock were 6, there's only 4 jetplanes when they approach the Golden Gate bridge and the number of jets flying under the bridge is 5.
Revealing mistake: During the car chase, when the first FBI car flips over, the device used to flip it over is visible on its underside. (00:45:55)
Factual error: When Cage gets into the Ferrari, the camera changes for a few seconds showing the gearbox. In slow motion it is obvious that Cage shifts into 3rd gear instead of 1st, however the car makes a very impressive tyre-burning start. The F355 is indeed a very powerful car, but this would be simply impossible to do in 3rd gear. (00:44:14)
Suggested correction: He was not doing a stationary burnout. He was moving forward the entire time, and is completely possible especially if the car isn't stock.
Continuity mistake: When Nicolas Cage drives through the window in the yellow Ferrari and the shot changes, he is coming out from a different window than in the first shot. In the first shot he emerges from the window to the left of the 7th Street Garage storefront ('Classic Autos' written on the window), but next shot he emerges from the window to the storefront's right. Also, note the now glassless window to the storefront's left, due to a previous take.
Continuity mistake: While in the chamber Isherwood shows his glove and says it is eating them. We see him looking through his helmet at the glove and it is covered in foam, however in the next shot from the outside, there is no foam at all. (00:09:55)
Revealing mistake: During the big chase scene when the tram is out of control as it hits the last car and blows up you can see rubber tires on it, specially added to let it go on tarmac.
Visible crew/equipment: Right near the very end where you have the overhead shot of the bombs hitting the back of the island you see Stanley Goodspeed being thrown through the air by the force of the explosion, and into the water. As he is flying through the air you can see the wires he is attached to, to make him fly.
