Revealing: During the hotel scene where Arnold is on the horse chasing the bad guy on the motorcycle, keep your eye on the carpet. As the bike clears a path through the lobby, you can see tyre marks all over the carpet where this shot has been practised many times.

Revealing: 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.

Revealing: When Helen Tasker pretends to be the hooker, Doris, at the hotel room, she does a striptease and you can see a burn scar on her right hip from a childhood accident. Then it is gone during closeups, as a body double is used.

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.]

Revealing: 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.

Deliberate "mistake": In the scene where the bad guy is attached to the missile and fired, in the split second before it hits the helicopter you can see below it a building called SUN BANK, but the letters are backwards. A close look reveals the likely reason - to the right of the reversed building is one which looks just like the building to the LEFT of the Sun Bank building behind the harrier a few seconds earlier. Most likely they couldn't film the chopper from the right side because there was a building there (the one the camera flies through), so they filmed it from the other side (the same side they'd filmed the harrier from), catching the "Sun Bank" behind, then had to flip it to have everything facing the right way.

Continuity: In the scene when Harry brings Helen's purse to Gibbs in the van, it is raining very hard. When Harry is standing along side of the van talking to Gibbs who is in the van, he is not getting wet and there is no rain falling when the camera is facing in towards the van. However, when the camera angle is facing out away from the van, it is pouring rain and Harry is getting wet.

Revealing: 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 Scharzenegger's double on the horse.

Continuity: Throughout the limo chase scene, Tia's scratch on her face disappears and changes from cheek to cheek.

Continuity: 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.

Revealing: When all the terrorists are firing their guns at the sky near the end, one of the men is clearly pulling the trigger, and empty cartridge cases are coming out, but there is no muzzle flash like the other guns.

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.

Factual error: When the terrorist leader has fired his gun at the toilets you can see and count the bullet holes. A AK-74SU clip holds 30 rounds yet there are about 100 bullet holes in the toilets.

Visible crew/equipment: During the Corvette scene when Arnold is driving, there is a shot looking at Bill Paxton talking and on his shoulder is the shadow of the boom mike.

Revealing: 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.

Factual error: When the bad guy is stuck on the missile on the rail of the Harrier, and Arnold shoots it, it carries the bad guy into the building and out the other side. Modern missiles accelerate at more than 2000 G's - the Sidewinder weighs less than 200 lbs, and thrust is more than 40,000. So he would have been fried by the backwash as it left without him.

Revealing: When Arnie's interrogating his wife, Tom Arnold says "but he's not exactly ringing your bell these days", and you can see the audio monitor on the left peaking as he speaks. It then goes flat a second or two before Arnie covers the microphone up.

Continuity: In the scene where Harry is trying to get the truth from Gibb about Helen's phone conversation, the van pulls over and the wheels are facing to the right. They get out and talk and Harry then punches the window through. As they get back in the van and pull away, the wheels are facing the opposite direction.

Continuity: When the bad guy rides the motorbike through a kitchen door two servants drop some food on the floor. When Harry rides his horse through the door there is nothing on the floor. [Only visible in pan and scan version].

Revealing: 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.
