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: In the beginning when Kruger lures one of the bad guys out by carefully opening the door, we see the bad guy go out the door pointing his gun up. When it cuts from outside he is pointing his gun forward. (00:03:10)
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: 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: 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 Kruger is figuring out which one of the three ID's that are fake, in the close-up shot you can see two different scales and a photograph on the table next to the ID's. When it cuts they are gone. (00:08:45)
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)
Continuity mistake: When Cullen enters the combination for the vault it cuts to the agents following her moves with one of them saying "Bingo." Look at the surveillance screen behind him and you should be able to see Cullen opening the vault door. When it cuts she opens it again. (00:14:30)
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 Donahue shoots himself in the head there is one shot where his eyes are closed. Then suddenly they are open. (00:19:40)
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: 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: 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: 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: When Robert is strangling his witness we see her grabbing onto the rug with her left hand. When it cuts she suddenly has her hand by Robert's waist. (00:43:55)
Continuity mistake: You can see twice when bad guys are shot when the tape is cut and edited. The first one is when Arnold shoots the bad guy with the shot gun when looking for the blonde girl in the house, you can see just before he hits the picture on the wall that the tape is cut and replaced with the real guy instead of the dummy that was hit by the bullet. The second is at the end at the dock when Arnold has two of those really cool guns. He shoots a vehicle full of guys coming towards him and the vehicle blows up and flies over his head, and just before the vehicle blows up, you can see the cut & edit and then the car blows up and flies through the air. Undoubtedly replaced with a toy car that was blown up! (00:44:35)
Continuity mistake: When Kruger is getting dizzy from the poisonous water he stumbles against a seat with both his hands down. When it cuts he suddenly has his right hand against the wall. (00:46:20)
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: 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: 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)
