Revealing mistake: During the battle in Egypt, while Sam is down, there is a slow-motion shot from above with a UH-1 Iroquois (Huey) helicopter flying under the camera. The helicopter is bright white with high-visibility red and yellow stripes, and you can see "White Sands Missile Range" painted on both sides of the body of the chopper in the view from above. It appears to be a UH-1H SAR (Search And Rescue) chopper from White Sands Missile Range in New Mexico: the colors and markings match.

Revealing mistake: In one of the first scenes with Devastator 'inhaling' everything in sight, there is an SFX shot of some random bystander hanging on for dear life, then losing his grip and being sucked in. During this shot you can see the matte halo around the person as they flail and 'fall'. It is especially noticeable given the general high quality of the effects in the film: by contrast this looks like a cheap effects shot from an old movie.
