Continuity: Arnold goes to the Gay Bar to solicit the help of the guy he saved at the beginning of the movie. The guy is wearing a white shirt and a black vest. During their conversation he takes off the vest, then the scene shifts to another bartender. When it comes back the guy has the vest on, another shot and the vest is off again.

Continuity: Even aside from the ridiculous recoil that a railgun would cause (yeah, I know they don't use gunpowder, but there's got to be SOME opposite movement, surely), how come when the darts (bullets, whatever) go straight through people, they still get thrown backwards? The passage straight through them means minimal energy being transferred to them, and as such they shouldn't be hurled backwards that much.

Continuity: If the bullets from the super gun move at just under the speed of light, how come the bad guys can't hit him or the girl? The bullets would arrive almost instantaneously and that would mean minimal compensation for them running. Plus the guy had them locked on when he shot.

Continuity: At the end, right before the train crashes into the limo, the back of the limo is facing the blocking rail. However, after the train hits the limo, the front half of the car is right next to the rail, and the rear half is nowhere to be seen.

Factual error: The bad guys are able to close in on Vanessa Williams at the end by tracing the signal Arnie sends to her beeper. How could they triangulate her location through a passive, receptive device? Maybe if it was a cell phone, but not a pager.

Continuity: When Arnold gives the girl a credit card, he slides the card to give her credit, but the magnetic strip is facing the wrong way.

Continuity: When Arnold is hanging under the parachute the plane tries to hit him and he shoots at the plane, breaking the glass of the cockpit windows. When the plane lands later on, the windows are intact again.

Continuity: Arnold dives to save the girl under the lid of a fridge. Knives are thrown at him with his hand above the fridge door. The knives are all thrown and none hit his hand. But the next angle shown he's got one in his hand. Even worse - in the next scene he's driving a van with both hands, and when he swipes the credit card the wound appears and disappears.

Continuity: When Arnold is in the plane and throws his belt buckle-knife at the traitor. The next shot shows that it bounces off and continues to spin. Pretty obvious that it's held up by a wire.

Revealing: At the end right before the van blows up, we see John and the girl get in to it - if you look very closely, John disappears at the exact second the door closes.

Continuity: After the court scene, when Arnold and Vanessa are making their exit toward the van, they get in, the van explodes and the camera pans to the underside of the van, showing Arnold pulling a manhole cover closed. The manhole cover was not there when they showed the van from a distance and they didn't have enough time to get in the van and escape through the bottom. Also, because several seconds passed before he closed the manhole cover you would have to assume he was still above ground when the bomb went off, therefore killing him.

Visible crew/equipment: In the scene where the warehouse has collapsed on Arnold and he is coming out from underneath the rubble, you can see a guy "hidden" behind some tubes, wearing protective eye wear and holding a welding rod to make a shower of sparks (he is only visible in the widescreen DVD version).

Continuity: Arnold is handed an upside down photograph of his friend's witness. As he views it the photograph is correctly oriented without being turned around.

Visible crew/equipment: When Cullen is walking down the hall towards the vault we get a camera view where the camera turns to the left, then it turns to the right. If you look closely in the window as the camera turns right you should be able to see the camera man moving.

Factual error: In the scene where the Feds are going to the log cabin, while they are outside, gearing up, Arnold casually attaches a silencer, and pulls back the slide of his pistol, but the slide stays in the rearward position, a condition which should only occur when an empty magazine is in the weapon. Arnold notices and tries to push it foreward, this doesn't work so Arnold hides it with his hand for the remainder of the scene.

Continuity: In the beginning outside Johnny's house we see one of the bad guys closing the curtains. When it cuts to a shot from inside the house he close the curtains again.

Continuity: It's astonishing that Arnold still has a gun after he jumps out of the plane since he didn't holster it before he jumped. Still he pulls it out of his holster before he shoots the plane and during the shootout in the zoo. It's also pretty strange that this weapon, a Desert Eagle .357, fits into the holster, since Arnie's first pistol (the one the young Marshal was shot with) is much smaller. Another fascinating thing about the gun is the fact it has a maximum capacity of nine bullets plus one in the chamber but Arnie fires about 15 or 16 times.

Continuity: After Arnold wakes up from being drugged on the plane, James Caan is holding up Arnold's gun in a plastic bag. On the close-up the barrel is pointing up, on the wide-angle shot the gun is laying down with the barrel pointing sideways.

Revealing: When Arnie jumps from the plane, notice the stunt double. He weighs about half of what Arnie would, and has no muscles.

Factual error: When Arnie shoots out the cockpit window, first of all the glass seems about as thick as a Coke bottle which in reality it isn't. Secondly it shatters like one, not like the modern safety glass which it would be made of.
