Several of the zombies are shown clawing their way out of the ground, yet when they have finished, there is no dirt in their hair or on their clothes.
The appearance of the zombie girls changes from black make-up under their eyes to scars and blood whenever there is a shot of them looking in a mirror.
Crew or equipment visible
You can see the camera man in the reflection of the red car about 15-20 minutes into the movie.
