Continuity mistake: 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 vest black/gold lamay. During their conversation he takes off the vest, then it cuts to another bartender. When it cuts back the guy has the vest on, another shot and the vest is off again. (00:08:05 - 01:10:50)
Continuity mistake: 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. (00:36:50)
Continuity mistake: 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. (01:48:30)
Continuity mistake: Arnold dives to save the girl under the lid of a fridge. When all the drill bits are shot at him with his hand above the fridge door, none hit his hand. But in the next angle one penetrated his hand. Then in the next scene, when he's driving the van with both hands and when he swipes the credit card the wound appears and disappears. (00:28:30)
Continuity mistake: 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. (01:46:20)
Continuity mistake: 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. (00:56:25 - 00:58:15)
Continuity mistake: 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. (00:02:45)
Continuity mistake: When Arnold blasts out of the warehouse with 2 EM Guns, a man is firing at him, standing right next to a surveillance van. Arnold fires back and blows the whole van up but the man is gone. (01:38:20)
Continuity mistake: 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. (00:51:35)
Continuity mistake: 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. (00:41:05)
Continuity mistake: 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. (00:56:20)
Continuity mistake: In the beginning when Kruger puts the gun in the dead hit man's hand, you can see Kruger's gloves are covered in blood. When it cuts to Kruger grabbing his phone his gloves are entirely clean. (00:05:30)
Continuity mistake: After Cullen has been picked up by the FBI agents they are sitting by a table where Cullen is explained there would be risks. There is a coffee pot on the table and a white paper cup on its right side. When it cuts the paper cup has moved to the other side of the pot. (00:20:25)
Continuity mistake: When Lee sits down to copy the files from Cyrex, the wide shot shows the clock as 10:25, a few seconds later Lee checks her watch then looks at the clock on the wall which then changes to 10:26 but then after she is done making the second copy the clock on the wall is back to 10:25 again. (00:16:25)
Continuity mistake: When Lee's disc is delivered (and stolen) from evidence lockup, the courier delivers the disc inside a briefcase. He hands it over while holding it with just one hand. In the next shot, he's holding it with both hands.
Continuity mistake: As Kruger puts the dead gangsters on the lawn, he pulls out a bag filled with fake blood. A second later, it suddenly changes to two photos of the victims.
Continuity mistake: In the beginning of the movie when John Kruger goes to Lee's house with the balloons; Darryl gets shot and John and Lee leave the house, get in the van and drive away. One of the guys outside shoots at the van twice, shattering the back two windows and putting two bullet holes in the windshield. In the next shot of John and Lee through the windshield, there are no bullet holes. The shot after that when they drive away, the shattered windows are not shattered anymore - you can see the reflection of light on the windows as they drive off.
Continuity mistake: During the scene near the beginning where Arnie sends the abandoned car into the river, have a look at the front passenger window. It is closed when they all get out of the car but is then fully open as the car hits the water. (00:07:40)
Continuity mistake: When John Kruger and the woman are discovered in the Cyrez office using the computer, John grabs her with both arms and throws her to the ground. In the next shot, with them still falling on the ground, John now magically has his gun in his hand to start shooting, which isn't possible in the time difference from the previous shot, and the fact he was holding her with two hands. (01:22:50)
Continuity mistake: In Chief Beller's office when Kruger is handed Cullen's file, Kruger sits down while holding his left hand in the middle of the file. When it cuts his hand has moved out to the corner of the file. (00:11:25)
