Revealing mistake: In many of the scenes taking place in outer space, if you look closely you can see polygon borders surrounding space vehicles (X-Wings, Star Destroyers, and even the Death Star) indicating the objects being superimposed into the outer space background. [This mistake may only apply to the Blu Ray version.]
Revealing mistake: In the early part of the film, Beverly D'Angelo and Chevy Chase check into the hotel/motel. She goes in to take a shower but he barges in. If you look real closely, she is wearing underpants and is not nude although she is taking a shower.
Revealing mistake: In the scene where Bond is trying to escape with his new Mini-Jet, he flies through a big hall. If you look carefully, you can see that the aeroplane which is supposed to be flying with its wings vertical is fastened to some kind of sustainer.
Revealing mistake: At the beginning of the film, Bond is on a training exercise to free a trapped hostage. Since it is only a training exercise, everyone involved is using blanks in their weapons. Why is it that when Bond fires an automatic rifle, we hear multiple bullets ricocheting? (00:03:25)
Revealing mistake: When Superman gets blown away by the bombs, he is being smashed onto the rocks. You can easily see that the rocks aren't real, but also that when he rises up again, you can see the cardboard rocks dent.
Revealing mistake: In the scene in which Alan Shepard is about to land his jet on the aircraft carrier, the plane seen from the outside is a single-seat A-4 attack plane. But inside the cockpit actor Scott Glenn lowers his sunshade, and reflected on the shade can be seen the wings of a two-seat jet trainer, the T-33A.
Revealing mistake: During the Amazon women sequence, when Niki gets pulled underwater you can tell by the movement of the water that it was shot in reverse. (00:49:32)
Revealing mistake: There's a short ramp by a truck's cargo bed, but when the bikers ride over it, it's become a longer ramp that goes up to the cabin to allow for the stunt. (00:06:14)
