The movie was filmed in Morristown, Tennessee, where The Evil Dead (1981) was also filmed. The brick used by Karen as a doorstop when she throws out the garbage is from the original The Evil Dead (1981) cabin, which burned down in the early 1980s.
Filmed in a working factory at nighttime and on weekends over the course of seven months.
The opening credits shot was filmed in one take, with no hidden cuts.
On one occasion during filming, the crew missed cleaning up some fake blood from the floor. The next morning, workers saw the blood and reported it to management as a possible workplace injury.
While rehearsing the bathroom fight scene, Hunter Tinney fell against and broke a toilet. It was replaced by the factory owner at no cost to the production.
