Continuity mistake: Early on when Arnold is setting a bomb up in Austria, he has his coat on. In the very next shot, it's off. Then it's back on again. (00:04:05)
Factual error: At the start, when Schwarzenegger leaves the party to steal the computer evidence, when he turns on the computer you can clearly hear the Macintosh start up sound, but when he looks at the computer screen it is the Windows loading screen. It's not a case of changing the sound files - PCs make no noise before Windows is fully loaded except perhaps the initial beep. (00:07:15)
Revealing mistake: In the scene at the beginning of the film where Faisal is in the van and decrypting the files, he says "Yeah, I got your password," and then the camera swings down to show his fingers on the keyboard, pressing repeatedly on the same set of keys and looking rather unrealistic. (00:07:30)
Continuity mistake: In Switzerland, after Harry talks to Juno, there's an underwater angle of the huge crack in the ice through which Harry exited. From the guard's point of view, half a second later, the hole is a mere crack. (00:08:50)
Continuity mistake: During Harry's Tango with Juno, she bends backwards twice, the second one a couple is dancing right behind them. In the opposite angle it's a different couple and they're walking. (00:10:30)
Revealing mistake: At the beginning of the movie, during the scene were Arnold is being chased by the 2 Dobermans, the dogs jump up to get him and he knocks them out by bashing their heads together. Look closely as the dogs fall because you will see that they are obviously two rubber figures of dogs and bounce when they land. (00:12:10)
Revealing mistake: During the scene where Arnold's character is escaping from the mansion at the beginning of the movie, there is a part where he is running down a snowy hill through trees. At one point during the hill scene, Arnold does a flip head first. When he lands the flip, you can clearly see the stunt double's face as he turns to shoot at more bad guys. (00:13:30)
Continuity mistake: In the beginning of the movie, at Switzerland, Harry has just ran & tumbled in the snow, but doesn't show a speck of snow anywhere on him. (00:13:40)
Continuity mistake: After the Swiss scene, Harry, Albert and Faisil are in the office. Albert talks about the Chinese woman and the dozens screens behind are broadcasting news reports. When they walk away, a mere frame later, the images on the screens surrounding are completely different, now broadcasting satellite images and computer texts. (00:21:35)
Continuity mistake: Harry leaves the pack of cigarettes 15 cm away from the sink, in the close-up it's right next to it. (00:29:40)
Revealing mistake: In the restroom fight scene, the first villain shot by Arnold randomly shoots his gun as he is dying. Some of the stray bullets hit the urinals. As the camera angle changes to show the bullets hitting the urinal, large flames can be seen as the urinal explodes and falls to pieces. There must have been a small explosive used to make this happen, as the bullet impact wouldn't do this. (00:30:00)
Revealing mistake: During the bathroom scene, all the backshots of Arnie taking a pee are of a very obvious stand-in, not the real actor. (00:30:05)
Revealing mistake: During the shoot-out in the restroom, the villain fires shots down the length of stalls. Then as he walks down kicking each door open there is a shot from inside one of the stalls. You can see where the explosives were taped to the back of the door to make the gun shoot holes. There is residue on the back of the door and all of these rectangular clean area where the holes ended up being. (00:31:50)
Audio problem: In the public restroom fight, Arnold slams one of the bad guys head into the ceramic urinal. Although you hear two loud and clear "klonks", the urinal bends when Arnold presses the bad guy's head down. [Only visible in the pan and scan version.] (00:31:55)
Factual error: When the terrorist leader has fired his gun at the toilets you can see and count the bullet holes. A AK-74SU magazine holds 30 rounds yet there are about 100 bullet holes in the toilets. (00:32:40)
Factual error: The shots fired in the toilet are fired at a very narrow angle at the toilet doors. But when you see the holes up close they are perfectly round. They should be elongated. (00:32:40)
Continuity mistake: After the shootout in the restroom, close to a hundred rounds were fired, all from LOUD guns, yet when Arnold and the terrorist are running through the mall and out the window, people are standing around in the stores, like they never heard a thing. Heck, that AK-47 would even be heard by the people outside on the street. The only one to hear anything is the guy on the toilet. (00:33:30)
Continuity mistake: When Harry is racing the police horse through the park and hotel you see the end of his reins flip up several times. They are regulation length leather reins. Yet when the horse stops and flips him off over the edge of the building, suddenly the reins are about 10 feet long and much thicker. Also, in reality, the reins would probably have snapped or the bridle would have broken had 200 plus pounds hit the end of them at that speed. (00:34:45)
Revealing mistake: After the bathroom shootout, when Harry Tasker has his team contain the terrorist leader in front of the building they're about to chase through, just before the terrorist rides the motorcycle through the front door, if you watch carefully, you can very clearly spot Arnold Schwarzenegger's double on the horse. (00:35:35 - 00:36:40)
Audio problem: When the motorbike drives through the Marriot - on carpet - its tires makes sounds as if on concrete. (00:35:50)
Chosen answer: He just exclaims, "Shit!" It's not what he says that makes the henchman let him go, it's that they both realize that if they don't find cover they'll both likely be shot by this random, firing Uzi.
