Insidious: The Red Door release date

Insidious: The Red Door is coming to cinemas globally on Friday, 7 July.

It's five years since the previous film, Insidious: The Last Key, was released in 2018.

Insidious: The Red Door plot

The Red Door is set 10 years after the events of Insidious: Chapter 2, which saw Josh and Renai Lambert attempt to uncover the secret behind why they are connected to the spirit world. The film ended with the family having their memories suppressed after escaping from the spirit world.

Now, a decade later, the Lambert's son Dalton is off to university and spirits from the past are back to haunt the family once again.

The official synopsis reads: "To put their demons to rest once and for all, Josh and a college-aged Dalton must go deeper into The Further than ever before, facing their family’s dark past and a host of new and more horrifying terrors that lurk behind the red door."

The film will reportedly by Wilson's last stint as Josh Lambert but the actor-turned-director is keen to keep the family spirit of the movie going, sharing his dream of making Insidious the Boyhood of horror movies.

"Well, the quick answer is yes," he told Entertainment Weekly when asked if this is his final fright.

"But I will say, and this is probably not the best way to sell a movie, but it would be cool if way down the line, if Insidious was like the Boyhood of horror movies. Ty could do these movies for a long time.

"I think that's really exciting as a filmmaker to do that and think it's exciting for an audience to see that. I'm sure it's exciting for a studio because the IP doesn't go away for a studio.

"But Josh and Renai? Speaking on behalf of Rose, no. I think we close our door."

Insidious: The Red Door cast

Patrick Wilson and Rose Byrne return to the series after being absent since the second film and so do Ty Simpkins and Andrew Astor as their sons Dalton and Foster.

Lin Shaye, the only actor to star in every Insidious film — despite dying in the first movie — will also reprise her role as Elise Rainier.

New additions to the cast are Succession star Hiam Abbass and professional gamer Peter Dager.

Insidious: The Red Door trailer

As anticipation builds for the horror sequel, Sony Pictures released a trailer for The Red Door that offers a first look at Wilson and Byrne in their roles.

Insidious: The Red Door director

As well as leading the cast, Patrick Wilson will also be stepping behind the camera for the first time in his career.

He will be the franchise's fourth director after James Wan directed the first two films, Leigh Whannell helmed the third and Adam Robitel was behind the camera for the most recent movie.

Whannell has also written the story for The Red Door while the screenplay was penned by Scott Teems who's credits include Halloween Kills and Firestarter.

Speaking to GameSpot, Wilson recently divulged some of the themes he wanted to touch upon whilst directing this new instalment of the Insidious franchise.

"I really wanted to unpack the second movie and address the trauma. That's the only way that I knew how to make a movie that I was passionate about, that I felt like I had any authority to make," he explained. "So luckily, I'm surrounded by people that are longtime collaborators and knew that they would trust me and be there for questions and help and which, of course I used."

Insidious: The Red Door is in cinemas from Friday, 7 July.
