(at around 39 mins) At one point in the film, a female zombie can be seen walking through a field with the house in the background. This zombie hears the banging from the humans in the house trying to board up the windows and is attracted to the noise, so she turns and begins staggering to the house. This woman actually owned the house in real life. The producers wanted to use the house in the film and agreed to give the woman a small acting part in exchange.
This is the only film in the George Romero-associated "Living Dead" series in which the date of the zombie uprising is mentioned (over a radio near the end) - August 23, 1989. However, in the unaffiliated The Return of the Living Dead (1985), at the beginning of the movie the caption reads: "July 3, 1984 5:30 P.M. Eastern Daylight Time."
The Mercedes driven by Johnny at the beginning of the film was owned by Tom Savini. According to the director, it was the first car he bought after meeting with success and it broke his heart to wreck it during filming.
