Continuity mistake: When Ash is crawling through the cellar, he finds some of the pages, and he holds them in his right hand. Only problem is, he cut off his right hand earlier and attached the chainsaw to it - the film was flipped so he'd appear to be crawling in the right direction. (01:06:15)
Continuity mistake: Near the middle of the film we see that Michael has a transparent reflection in a mirror because he is a half vampire. Yet, earlier in the film when the other vampires, who are full vampires, are in the video store, their reflections can be clearly seen in a glass counter. (00:12:10)

Continuity mistake: When Walter is being rescued from the room he was trapped in, through the hole in the wall, we see the outside of the hole and Walter's body is outside except for his legs, and we see the hands trying to pull him back. In the next shot inside the room, Walter is again inside except for his head and arms. It repeats several times. (01:28:30)
Suggested correction: This is incorrect. Walter and Lisa are wearing similar clothes, making it look like he is in both rooms at once. Instead, as he is almost completely in the other room, Lisa is close behind him.

The camera angle switches to a wide shot as the car drives by. At this time, the back window (which was just blacked out) has not been spray painted yet. It is totally clean again.
Continuity mistake: When Jerry throws all the knifes on the table he picks up a certain knife. It cuts to another shot and you see him pick up the knife again, but it isn't the same knife anymore. The knife he picked up in the first place is still on the table. (01:12:25)
Continuity mistake: When Horace is confronted by the Gillman and has picked up the shotgun, he looks inside and sees E.J. and another kid hiding behind the counter. Horace begs them to let him in.

A few seconds later, a distant shot shows the two shaking their heads and lowering themselves behind the counter again.
