The screenplay had a subplot about a film named "Frankenstein and the Witchhunter", a kind of Hammer films exploitation that the characters of Matthias and his wife attend thanks to free tickets from the radio station. Rob Zombie shot this "film-within-the-film" with Udo Kier, Camille Keaton, Clint Howard, Daniel Roebuck and Richard Lynch. But all the scenes related were deleted from the final cut.
Rob Zombie wrote himself a novelization of the film along with writer Brian Evenson. According to Zombie, the novelization is based on his original screenplay, which differs significantly from the final script used in the film.
