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?
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.
