Revealing mistake: When Ace and Melissa are in bed together having sex if you look close enough you can see that she is wearing underwear. (00:45:35)
Revealing mistake: If you look at the missing part of the bridge, and look at the shadow underneath, the shadow is of a full bridge. (01:02:35)
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)
Revealing mistake: When Picard is trying to squeeze through the rock archway, he looks like he's stuck, but a closer look reveals he has enough room above his back to squeeze through without any trouble.
Revealing mistake: When Jack Ryan goes to Ernesto Escabeda's residence and asks to see Ernesto, as he is led up to the house we see his two companions on a roof top ledge watching through binoculars and one of them says "He's in", if you look at that shot closely the suppressor on the mp5 laying next to the sniper is fitted at a decidedly wonky looking angle.
Revealing mistake: When Draven sends T-bird to his death in his car, the real Ford Thunderbird is replaced by a fake mockup using a flimsy one-piece fiberglass body mounted on a pair of straight axles. When it explodes, the body lifts off in one piece, warping wildly while the front axle simply falls away. No proper car components like engine, transmission, suspension and so on, are seen anywhere, though they should be. (00:57:05)
Revealing mistake: When Brad Renfro is standing outside Reggie Love's house, hitch-hiking, he is laughing so hard he has to turn away from the camera, and even then he is still visibly shaking with laughter.
Revealing mistake: The BMW crashes through a metal gate at the border but does not suffer as much as a scratch.
Revealing mistake: Whenever Will does one of his fancy jumps (which make him actually appear more like a monkey than a wolf) you can easily tell that he gets pulled up by a rope because always accelerates on the way up. If he were jumping his maximum speed would be at the moment when he takes off. The softened landings enhance the unrealistic impression. (01:06:35)
Revealing mistake: In the big wheel, the boy falls out and grabs Axel's leg. When it zooms out, it is a man climbing his leg.
Revealing mistake: When the glove comes up the car seat and into Porter's chest, there are lights from buildings out the side window, so the car isn't moving at all. When it cuts, there's suddenly a hill where the lights should be and now the car is moving again. (00:29:30)
Revealing mistake: When Gail throws a stone to make it bounce on the water you see in slow motion that she fakes the throw with an empty hand, and only in the next shot do you actually see the stone bouncing. (00:27:25)
Revealing mistake: Near the end of the film, when the Cadillac Allante is falling, watch closely and you will see it explode just before it hits the ground.
Revealing mistake: Near the beginning, when Van Damme goes and arrests his former partner, watch when they both jump out the window. It is clear that they are on a cable decelerator. They fall straight down and in a controlled and slightly slowed motion. Very noticeable.
Revealing mistake: After the SWAT team grab Mathilda, the guy who grabbed her backs up against the wall and it bends inward, revealing it to be a set.
Revealing mistake: As Kate drives the Jeep downhill near the end of the movie and swerves the Jeep quickly to avoid another vehicle, her head and body remain upright throughout the maneuver. Of course she was no doubt in front of a blue screen, or on a set, so there was no violent maneuvering to react to.
Revealing mistake: At the black market, Honda and Balrog bring Ryu into the tent that Ken is already restrained in. When they enter, Ryu begins to fight with Honda and Balrog but Chun-Li ends their fighting by emerging from a curtain wielding a knife. Ryu backs into the knife and it bends.
Revealing mistake: Most of the police cars are late model Ford Sierras, but any police car that crashes has been substituted for a much older early model Sierra.
Revealing mistake: Near the end of the film when Jess is hanging from underneath the plane, you see her normal thin body frame. When see lets go, you can see that her body shape has changed and there is a parachute pack underneath her jacket.
