Blood Frenzy is a 1987 American slasher film directed by Hal Freeman, and starring Lisa Loring amongst others.
The film was based on a script by Ray Dennis Steckler called Warning - No Trespassing.
Ted Newsom was hired to rewrite by Hal Freeman, who had made a lot of money making pornographic films and wanted to expand into other genres.
Newsom wrote a follow-up for Freeman called Judgment Night about a convicted murderer who escapes prison and seeks revenge.
