Continuity: At the end, the buried biker digs himself out of his grave and shuffles to the smokehouse. When he attacks Farmer Vincent, all the soil and mud stains have vanished from his clothing. Guess he must have stopped off at Zombies-R-Us for some fresh new duds.

Visible crew/equipment: When the trooper gets out of his patrol car and puts on his hat, his oversized sunglasses reflect the camera crew.
