Continuity mistake: When they are about to test the laser on the doll, they put glasses on everyone. But when everything goes wrong the black glasses are gone.
Suggested correction: Unless you're taking about a deleted scene, there was no doll test. The lab test was done on a crystal and you can see everyone still has their dark glasses on when it explodes. Even when Wayne shows up late they have it on. After he asks "what's that stuff on your face", we see people to start to take them off. Then the scene then cuts to Dr. Hendrickson already halfway up the stairs and that's when people don't have them, but enough time has passed for them to take them off.

Continuity mistake: When Adam is toying with the car in Las Vegas, the wide shot shows the girl's arms extended, but in the close-up they're covering her face. This swaps back and forth.
Continuity mistake: When Wayne is in the back of the van with his machine when the motorcycle cops are following him, the switches on the machine change position depending on the shot. At first, you see #2 and 5 in the up position, but then only #4 is. He flips them all up and the lights come on, but in the next shot, the lights are off and not all the switches are up. A similar thing happens when he unshrinks the cops.
Continuity mistake: In Las Vegas Adam slides the car and sparks come out. His brother is either holding the wheel or waving his arms, depending on the shot.
