The original version of "Horror High" was given an R rating by the MPAA. When the film was sold to Crown International, they cut some of the gore effects to make the film suitable for a PG rating. Mark Tenser, then president of Crown International, had additional scenes shot to pad out the run time that featured himself as Vernon's absent father, depicting brief events that have almost no connection to the story and do not feature any of the original actors seen in the film.
