Corrected entry: Fraser's girlfriend slams a chair against a soundproof glass and the glass shatters. Soundproof glass is usually 3 or 4 inches thick and is very hard to break. Also, if the glass wasn't soundproof, it should've been because most radio stations have those.
Corrected entry: When Chazz, while dressed as a delivery guy, is running from the security guards at Palantine Records, he slips into an elevator just as the doors are closing. Every elevator in every office building has a sensor that opens the doors back up when anything passes in front. This prevents people from being crushed. Those doors would have opened as he passed by, and the guards would have snagged him.
Corrected entry: In the very start of the movie when Brendan Fraser is about to go to the record producer he is seen taking his bike helmet off and leather jacket with a sleeveless black shirt on underneath. The next shot cuts to his hands putting his helmet in the saddle bags on his bike and he magically has grown a blue button up shirt on over the black sleeveless shirt.
