Continuity mistake: When Julia Costello goes to leave Ned Campbell's hotel room he grabs her by her upper arms. She did not even flinch, which considering she had recently been shot in the upper left arm is a little strange.
Continuity mistake: When Ned Campbell hits the Magnificent 7 slot for a win it had one the reels a single bar, then triple bar then double bar. They then show Rick Santoro and Kevin coming towards them. When we see a first person perspective shot from Kevin approaching them we see the reels all have double bar on them. (00:49:35)
Continuity mistake: After Nicholas Cage spits blood on Gary Sinise's ribbons, you can see that the ribbons got soaked with blood. But a few minutes later, when Sinise is tracking Cage by using the GPS, his ribbons are clean. The white parts of his ribbons are white as snow. Sinise did try to wipe the blood off his ribbons but he could not have wiped off all of the blood stains because the ribbons are made of cloth.
Continuity mistake: In the end, where the cops attempt to arrest Gary Sinise's character, look closely at his back near his left shoulder. There is a device jutting out under his shirt, which is used to create the effect of the bullet shot when he kills himself.
Continuity mistake: When the girl, the Navy guy and the fat guy are in the elevator going up, Nicholas Cage tells the guy watching the video surveillance camera to see what floor they pressed in the elevator. The video guy responds that he can't see what buttons they pressed because the buttons are too small. But when they show the monitor which shows what the elevator camera sees, you see the back of the elevator, not the front where the buttons are. Same when they show the inside of the elevator, and show the camera, the camera is angled from the front to the back of the elevator making it impossible to see the buttons which are on the front of the elevator by the door.
Continuity mistake: When Julia is explaining the conspiracy to Rick in the stairwell, the position of Rick's hands in front of his face change between shots. (01:03:25)
