Director, producer, and writer James Wan fostered a horror universe that aspires to be as interconnected as the Marvel CInematic Universe (MCU). This began with his 2013 hit film “The Conjuring,” which was graced with a direct sequel, and two spin-offs in “Annabelle,” and “Annabelle: Creation.” The so-called Wan-iverse is set to further expand with “The Nun” and “The Crooked Man.” Though it’s not interlocked with the Conjuring universe, Wan kickstarted the “Insidious” series in 2010. In Jan., 2018 the fourth series entry “Insidious: The Last Key” comes out. In advance of its theatrical debut, here’s the “Insidious: The Last Key” trailer #1.

In the first “Insidious” film, seer Elise Rainier gets knocked off. But she’s a prominent figure in “The Last Key,” which seems to center largely on her. Therefore, the latest “Insidious” franchise entry treads into prequel territory.

The trailer advertises “Insidious: The Last Key” as spawning “from producer James Wan.” Although Wan directed parts one and two, he passed on writing and directing duties to Leigh Whannell for chapter 3. Notably, while Wan directed chapter 2, Whannell wrote the screenplay and collaborated with Wan on the story.

“Insidious: Chapter 1” was a fresh take on the ghost story, and enjoyable despite the strange Darth Maul demon. “The Last Key” sees Whannell return as writer, with Adam Robitel taking the directorial reins. Whannell is poised to once again star in the film, as with “Chapter 3.”

From the trailer, “Insidious: The Last Key” seems vivid, and the effects looks solid. I’m excited for its potential to further expand the universe, and concentrate increasingly on Rainier. But it doesn’t seem all that new. Rather, its aesthetic is that of a typical haunted house story.

Regardless, Wan’s prouctions always deliver a stellar atmosphere with fantastic cinematography, effects, and score. Plus, as “Creation” proved, handing off directing duties does have its benefits.
