There is a post-credits dedication to Director Robert Thompson's mother, who passed away while the movie was still in post-production.
The movie was originally conceived, and written, as a web series. Rewrites were done to make it a shorter, more cohesive story, as a Feature.
The characters of Valerie, and Lucas, were originally one character. A female serial killer, with a trust-worthy, intelligent, girl-next-door personality.
