When Harry slips and falls while running, it was unscripted. Brandon Maggart really did slip, and Lewis Jackson used it in the film.
Director Lewis Jackson came up with the basic idea for this film after smoking marijuana one night during the 1970s and seeing a vision of Santa Claus holding a knife.
Although the success of Halloween - La notte delle streghe (1978) helped to get this film produced, it was written prior to that movie's release. Writer/director Lewis Jackson does not consider his movie to be a slasher film and feels that it has more in common with Frankenstein (1931).
