Revealing mistake: After Nuclear Man destroys the cab's hood, the shot changes and there's a thick string running behind him all along the car, and the cab driver is stretching out to pull it. Probably he was activating some sort of bad FX.
Revealing mistake: As the Predator tends to his wounded leg, one of his claws can be seen bending as if made of rubber.
Revealing mistake: In the shot where Dick Jones is falling from the top of the OCP building, both of his arms appear to be about a foot longer than they should be. (01:36:30)
Revealing mistake: When Jack is hanging out of the truck you can see him standing on the hood of the car which Lydia is driving. At some points we get camera view from the back seat of the car. In some angles the mirror inside the car disappear. This is to prevent us from seeing the camera. (01:04:15)
Revealing mistake: During the "Mondo Condo" scene, the books and vases on the bookcase seem to be glued on because as the bookcase falls on Arsenio Hall, when the camera shot is in his point of view, nothing falls off as the bookcase hits the ground.
Revealing mistake: When we see Dark Helmets' hoverjeep in the desert, watch the front end: you can clearly make out the edge of the mirrored box they used for the "hover" effect.
Revealing mistake: The Eternia out-door scenes depicting the conquest of the Castle Grayskull area are actually one long shot subdivided into smaller parts. Look at the captured Eternian soldiers marched to the castle; they cover very little distance between the shots.
Revealing mistake: Just before Walter throws Lisa through the window, you can tell that Lisa is a stuntman wearing a wig.
Revealing mistake: When Derek falls and is rolling down the cliff, it is a very clear dummy. It's legs and arms are in a stiff seated position. (00:23:15)
Revealing mistake: When Fireball takes off for the first time, if you look way above him at the top of the tower block behind him, you can see the shadow cast by the rig that is used to lift him up.
Revealing mistake: After Cherry has malfunctioned, in various shots, such as when she inanimately lies in bed with Sam, you can see her breathing and blinking. She is supposed to be an inanimate robot. (00:13:05)
Revealing mistake: When Ali Gator and Windy Winston are coming back from the barfight riding the atv's, Ali scratches his head and you can see where the green glove ends and the actors real skin is supposed to be, under the shirt.
Revealing mistake: When the elder Indian (Native American) with the black hat steps out of the yellow car at the beginning, and says hi to the shop owner, then Hi to the wooden Indian chief. You can see the Indian chief move slightly, indicating it is not a wooden statue, but a real person under the getup. (00:04:52)
Suggested correction: The scene where he moves is intentional. In fact, Old Chief Wood'nhead is played by Dan Kamin, and he moves a lot more later on.
Suggested correction: He does give a shocked look when he see's the statue move its head a bit.
Revealing mistake: When Marisa has her back to her window and you see Mason tossing out his paintings you can see wires attached to the paintings.
Revealing mistake: Terri is replaced by a stuntman in a dark blond wig once she puts on her motorcycle helmet outside the hardware store.
