The film was originally intended to be a short film back in June 2015 called "Factory of Gore". It was to be produced by David S. Sterling, directed by Alex Wesley, with a screenplay by Philip Brocklehurst. The basic premise of the project by Sterling was to make it a homage to the Japanese horror movie Guinea Pig: Devil's Experiment (1985). Wesley and Brocklehurst were given freedom to work a story around Sterling's instruction that it had to be a torture film.
Director Alex Wesley fell out with producer David S. Sterling a few days into the shoot after Sterling cut the already small budget in half, and due to a disagreement over the tight shooting schedule. Wesley took the project from Sterling, rewrote the original screenplay, and made it with Philip Brocklehurst serving as executive producer for the film.
The original screenplay, when the project was known as "Factory of Gore", was written in a week. The script needed to be completed quick before filming began the following week.
A novelization based on the original screenplay was written by Philip Brocklehurst, under his pen name: P.M. Thomas.
The original writer for the film, Philip Brocklehurst, was never disappointed with Alex Wesley rewriting the script, he encouraged it. Although Brocklehurst liked the original script he wrote, he felt it had certain elements that were held back due to the screenplay having to be completed quickly to meet the short deadline and the story having to be restricted from its true potential in order to fit the very small budget at the time.
