The movie was taken from Jimmy Westmoreland's collection of novellas, Quad, and was titled Oct. 21. The name was changed after the director overheard a conversation including the phrase "the devil lives in Hot Springs".
The actress playing the character Laura Dunn went on vacation during shooting, and returned with a haircut - the movie takes place over the course of one night. The "haircut" scene had to be written in at the last minute.
