Trivia: "Keeping Up with the Joneses" was originally meant to be a sequel to the film "Mr. And Mrs. Smith," with Brad Pitt and Angelina Jolie both intended to return.

It also made 425 horsepower, which Tripp incorrectly states that the engine he pulled out of the truck made.

Trivia: While no official explanation was given as to why the planned theatrical release was canceled, it has been speculated by insiders that Universal bailed on the release due to the large number of franchise-based Sci-Fi and action films being released in 2016 providing too much competition for an original property such as "Spectral", as well as Universal being leery over the project after the disappointing domestic box office of one of their other major 2016 releases, "Warcraft."
Trivia: When Lockhart is in the sensory deprivation tank, the nurse that does a poor job of keeping an eye on him is reading "Der Zauberberg" by Thomas Mann, which obviously has at that point a common premise with the movie (the main character goes to a sanatorium in the Alps just as a visitor but ends up as an inmate). The novel was inspired by Mann's visit to his wife at a Swiss sanatorium which happened in 1912, same year as the picture fully unveiled in the finale.

Trivia: Spoilers: At one point during the climax, you can briefly see a creature with long arms and legs barging through a doorway for a split-second. Many viewers assumed that this was the titular "Blair Witch." However, the screenwriter has stated that any creatures/specters visible in the film are meant to be grotesque manifestations of the witch's past victims (with the long-limbed creature presumably being Heather given she's in the place where Heather died), and that as stated earlier in the film by one of the characters, nobody can actually "see" the witch herself.
Trivia: Jason Mewes was originally set to play the "Brahtzies", but had to drop out due to finding the makeup required for the roles far too claustrophobic.

Trivia: The film was originally written to be an introspective, existential dramedy geared towards adults about a troubled man who is turned into a cat.

Trivia: At the very beginning of the movie, as the car drives along towards the town, the music to Stephen Kings' The Shining plays.
