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: Mac and Dillon go after the Predator. The Predator is sitting in a tree, and Mac points him out to Dillon. They both agree that they see it and take position. Mac crawls underneath the alien and is killed by his laser. The Predator then sees Dillon and lasers his arm off. Dillon's arm falls to the ground with the gun firing. Quickly Dillon turns and reaches for the machine gun around his neck. When he turns you clearly see his bloody right stump and his right arm sticking out the bottom of his jacket. [Note: As far as I can work out, this has been cunningly edited out of the UK DVD version].
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.
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)
