Continuity mistake: After one woman gets her foot caught in a bear trap, in one shot the man she was running with is kneeling down, trying to open the trap, but in the next shot he is standing up, and then he once again kneels down and then begins to try and open it.
Visible crew/equipment: There is a shadow of camera on a zombie as it approaches the mansion and nears the camera.
Continuity mistake: In one scene, a woman throws a bucket of green liquid on a zombie (before setting fire to it). Between shots, the amount of green liquid on the zombie's clothes decreases.
Continuity mistake: As the zombie is pulling the woman closer to the shards of glass hanging around the door-frame, the shards hanging in the top right-hand corner of the door-frame change from shot to shot.
