In one of the earlier drafts of the screenplay, Steve was a vampire. However, this aspect was soon scrapped.
The lightnings for the storm were done with two photo cameras, shooting shortly after one another with their flashlights.
The hotel in the film was designed after old postcards of the "Alexandra School" in Moose Jaw, Canada.
One of the paintings in Steve's hotel room is a lost painting by Vincent Van Gogh called: "The Painter on his way to work". It is one of six paintings that were lost after being stolen by Nazis in WWII and is depicting Vincent himself. It hangs in the hotel to add to the mystery, age and history behind the building.
Filming wrapped on July 23rd, 2018.
