Revealing mistake: When there's a close-up of the needle going into Nica's arm, you can tell it's a fake needle - the tip is just flat, and there's no hole, unlike a real hypodermic needle. You can also spot where the fake needle "retracted" in the center.

Revealing mistake: When Claire is bitten by Chucky and she pulls her sleeve up, you can see where the prosthetic is blended into her arm in the first wide-shot. In both that shot, and another shot, you can also see the prosthetic unnaturally "bulging" slightly. It's also very visible in the scene where she's strapped down and Dr. Foley injects her.
