In early 2013, this film was in pre-production under a different title for a late-2013 release. (Originally to be titled "The Devil's Carnival 2: The Librarian") A 9-minute teaser-trailer was even released. However, little was heard of the film's development for the rest of the year. It wasn't until late 2014 that the film was again announced, now with the current title and new storyline.
