Six movies into a horror franchise, even the director knows what you're thinking.

Jacob Chase, writer-director of ‘Insidious: Out of the Further,’ the sixth entry in the long-running series, hit theaters Friday via Sony Pictures. He says he walked into the project fully aware of audience fatigue.

More than fight that skepticism, he used it to change the film into a standalone story that just happens to share the franchise's name.

Too many ‘Insidious’ movies, Chase says it out loud

Chase doesn't dodge the obvious criticism. He's a longtime fan of the series, but he openly admits five prior films is a lot to ask any audience to revisit.

As he puts it, this installment needed to feel like a fresh start, practically an original film that happens to carry the ‘Insidious’ name.

(SPOILER ALERT: The following discusses major plot points and the ending.)

The new film follows Gemma (Amelia Eve), who shares the series' astral-projection ability but with a dangerous twist. She can accidentally drag demons from The Further into the real world, all while confronting trauma inherited from her mother (Laura Gordon) and trying to protect her own daughter (Island Austin).

From charity haunted maze to horror filmmaker

Before directing ‘Come Play’ or this film, Chase ran Bigworm Sherwood Scare, a 1,800-foot charity haunted attraction in Northridge, California, with proceeds funding cystic fibrosis research.

Running that maze became an unlikely film school. Chase would review hidden-camera footage of guests, studying exactly where they tensed up or panicked, often in spots he never expected.

He came away convinced film-making and live scares work the same way, guiding an audience's expectations, then subverting them. In a maze, that's physical hallways, on screen, it's the camera.

Every jump scare had to mean 

Chase says he's no fan of jump scares that startle without payoff. His rule for this film is that every scare had to mark a real turning point for Gemma.

He points to her opening discovery of her ability as the clearest example.

A father's anxiety bleeds into the script

Chase wrote the script while becoming a father for the first time, and says that gave the film its emotional core, a woman desperately trying not to repeat her mother's mistakes.

That fear of passing down damage to the next generation became the foundation, with the horror built on top of it.

Pillow-fort set piece and an accidental ‘Backrooms’ rivalry

One standout sequence traps Gemma in an endless, maze-like pillow fort crawling with threats, tapping into the same liminal-space dread that made ‘Backrooms’ a hit this year, a similarity Chase noticed with relief when that film never actually entered a pillow fort itself.

He says the scene draws on his own fear of tight, disorienting spaces, citing ‘The Descent’ as a direct influence, and notes the cast and crew genuinely got lost inside the set while filming.

Real dentist story behind the film's squirmiest scenes

During wisdom teeth removal, he woke up mid-surgery after being under-sedated, began flailing, and accidentally struck the dentist, causing the drill to injure his lip and requiring stitches.

Chase is already moving on to an unannounced horror film at Blumhouse for Universal, backed by ‘Insidious’ producer Jason Blum.

Is horror getting personal or better at hiding it?

Chase's approach raises question, as more franchise directors mine their own fears to justify yet another sequel, is horror getting personal or better at disguising formula as authenticity?
