Continuity mistake: Jesse sneaks downstairs so that he can go out, but the doorbell rings, so he hides in a closet. As he walks down the stairs, there is a table with a white pot on the edge of it. In the next shot it's in the centre.
Visible crew/equipment: As Joey is driving the truck, he hits a zombie and goes over the kerb and drives into the electricity box. As he drives over the kerb you can see boards placed to help the van get up the kerb.
Continuity mistake: The head of the zombie woman which comes alive, is locked in a closet at Jesse's house. Yet at the end of the movie the same head has somehow managed to teleport itself to the electricity station.
Plot hole: When Jesse falls through the casket when he's trying to escape the mausoleum, he knocks a corpse to the ground with him. Wouldn't it stand to reason that this corpse would be reanimated when all the others are?
Continuity mistake: After Billy wipes away the dirt from the barrel, to reveal the words written on it, the amount of dirt wiped off changes between shots, evident by more of the writing becoming exposed.
