Continuity mistake: When Adam sets down Nick's guitar after breaking it, the head of the guitar is facing towards the loudspeaker, but in the next shot, it is facing away from it. (00:06:41)
My entry talks about the direction the guitar is facing between shots. Your entry does not mention this; it talks about the distance the guitar is from the loudspeaker between shots. That's not the same thing.
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.
