Actress and YouTuber Hannah Minx (aka Hannah Wagner) didn't attend the movie's premiere in November 2018 because she had been missing for almost a year. Kristina Klebe said in an interview that the last time she saw Minx was New Years Eve 2017 when Minx stayed at her house.
Dan Walker said he got the idea for the movie when a friend of his was doing some urban exploring and found the abandoned Santa's Village amusement park an hour and a half from Los Angeles. Walker visited it and loved it. He wrote the script and decided to film location shots there.
Susan Slaughter almost wasn't cast because she co-starred in the reality show Ghost Hunters International (2008). Director Dan Walker wanted actresses, not reality stars. Then the casting director pointed out she had a theater background and was very good, so Waller invited her to audition. He thought she was perfect, especially when she offered to do a topless scene.
