Continuity mistake: When the hillbilly is killed by Henrietta, blood is spraying everywhere, and Annie is totally drenched by it, but in the next shot, she is totally clean except for the one blood stain mentioned on this mistake page. (01:03:30)
Continuity mistake: There are 5 different colours of blood used throughout the movie. Ash always gets soaked by blood (either chopping Linda's head up, or hacking Professor Noble to pieces), but always ends up dry in the next shot. [The reason why there are 5 types of blood: The creators wanted to get an R rating instead of NC-17, so they used different colors for slime instead of blood. It failed, they got an NC-17 rating and then released it independently with a non-rated rating.] (00:22:00 - 00:45:30)
Continuity mistake: During the movie, you can see that the metal handle of the chainsaw switches between being thin and thick. This is because they had replaced the handle half way through the shoot and had just painted the regular one silver and brown.
