Visible crew/equipment: When Ben first arrives at the house, a zombie tries to get in through a door in the kitchen. Ben fights it off and tries to push it out the door. Initially, when he first closes the door on the zombie, the relfection of the cameraman is seen as clear as day in the window of the door.
Trivia: The bald, half-naked zombie that Barbara shoots several times after it comes up to the broken window barrier is a cab driver that director Tom Savini had met while being taken to the set one morning. During a conversation with the driver, Savini mentioned that he was doing a re-make of Night of the Living Dead, and when the cab driver expressed great interest, Savini asked him to come to the set to be used as an extra.
