The first film of George A. Romero's Dead series and John Russo's Living Dead series.
John Russo wrote a novelization of the film.
The film is public domain because the filmmakers failed to put a copyright on the original film print.
John Russo produced a 30th Anniversary edition of the film that incorporated newly shot footage, edits and a original soundtrack replacing the previous stock music that was used as a soundtrack. The new edition also spawned the sequel Children of the Living Dead.
The original budget was $114,000 and it was shot on 35mm.
