Continuity mistake: Lisa's shoes change between white flats and white sneakers at different points during the last few scenes.
Continuity mistake: When Jesse's sister gets the plastic claws out of the cereal box, she places them on her left hand. In another shot they are on her right. (00:07:10)
Other mistake: If Freddy ripped his scalp off, it would be his skull, not his bare brain. It's not like he pulled both of them off at once. Freddy's got a skull, as we saw when Tina took his face off in the first film, so why is the top of it missing in this one?
