The original actor who was going to play Chad dropped out because he didn't want to do a stunt and asked for a stunt double instead. The budget could not effort a stunt man so the production replaced the actor.
Production was almost shut down when a drunk homeless man raged onto the set and threatened to kill everyone. He was saying that this was a Holy field and that the crew were sinners with our monster and the scarecrow stand that looked like The Christ's cross. After a short but bloody fight the director called up 2 friends who worked in the security and secure the crew and cast safety.
This movie was filmed in only eight days.
The film has an extremely long opening credits sequence, unlike most films of its time, lasting for more than four minutes. The opening credits list everyone involved in the production of the film.
Another day was almost shut down when the lead actor, Lester, was falling in a coma because of diabetic problems which he didn't tell the production company about. They had to call the police which was good for another reason: The locals of a trailer park didn't really appreciate the presence of the movie crew filming there, after the police came by they were quiet.
