The INSIDIOUS franchise will continue with the release of INSIDIOUS: CHAPTER 4 on January 5th, 2018, but if you want a sneak preview of the next sequel/prequel this Halloween season Universal Studios Hollywood's Halloween Horror Nights event is the place to be.
On September 15th, the park will open up an all-new horror maze called Insidious: Beyond the Further, which is directly inspired by INSIDIOUS: CHAPTER 4. The press release even refers to this maze as a "living trailer" for the film.
Directed by Adam Robitel and written by Leigh Whannell, CHAPTER 4 has been shrouded in secrecy up to this point, but star Lin Shaye (who reprises the role of paranormal investigator Elise Rainier from the previous films) has revealed that it will be digging so deeply into her character's past that we'll even be introduced to her mother and father. A one-line description says that Elise will face
her most fearsome and personal haunting yet: in her own family home.
Similarly, the set-up for this maze also deals with Elise Rainier's past:
The creepy new maze will delve deep into brilliant parapsychologist Dr. Elise Rainier’s past, starting with a childhood in which her paranormal abilities emerged… until her mother’s untimely death by a demonic entity. Troubled by a lifetime of evil supernatural spirits trapped in the Further — a vacuous netherworld caught between the living and the dead — Dr. Rainier will take guests on an unsettling journey back in time through a portal into the Further… to defy the most depraved and intimidating beings that have tormented her since the 1950s.
Sounds cool to me. Unfortunately, I won't be in Hollywood to experience the maze, but hopefully some of you reading this will have a good time going through it.
