Everything to Know About the ‘Insidious’ Franchise Before ‘Out of the Further’ Releases

The Further is about to get a lot more crowded. The ‘Insidious’ saga consists of six installments spanning multiple time periods, creating a complex and chilling mythology. With the latest chapter on the horizon, now is the ideal moment to revisit how this haunted house franchise developed its world before plunging back into the darkness.

Since its debut in 2010, the franchise has become renowned for its effective jump scares and unsettling supernatural elements, a formula that has clearly paid off. The series now includes five released films over thirteen years, with a confirmed sixth set to hit theaters.

The films were initially released in theaters in this order: ‘Insidious’ in 2011, ‘Insidious: Chapter 2’ in 2013, ‘Insidious: Chapter 3’ in 2015, and ‘Insidious: The Last Key’ in 2018. ‘Insidious’ established the eerie tone of the franchise and introduced audiences to the Lambert family, while ‘Insidious: Chapter 2’ followed three years later to delve deeper into the supernatural realm first explored in the original film.

‘Insidious: Chapter 3’ serves as a prequel to the first film, directed by series creator Leigh Whannell. In this installment, the gifted yet reluctant psychic Elise Rainier, portrayed by Lin Shaye, is called upon to assist a troubled teenage girl who becomes the target of a malevolent entity.

The fifth film, ‘Insidious: The Red Door,’ made a significant impact, grossing over 182 million dollars worldwide against a 16 million dollar budget, making it the highest-grossing horror film of 2023. It stands as the top-grossing film in the entire franchise.

For horror fans who appreciate a clear timeline, things get intriguing. ‘Insidious’ does not unfold its complete story in the order of release, meaning understanding the connections requires following the chronological order of events instead.

After the Lambert family’s encounter with the Further, the franchise takes a step back in time, with ‘Chapter 3’ set three years earlier in 2007, functioning as the first film chronologically. The original 2010 film ‘Insidious,’ while first in release order, is actually third in the timeline, introducing the Lambert family as they become entangled in Elise’s past mistakes.

‘Insidious: The Last Key’ pushes even further back, taking viewers to the 1950s childhood home of demonologist Elise Rainier and her abusive upbringing, revealing how her gift allowed her to see ghosts, which frightened her father into disturbing extremes.

One night, while locked in the basement, Elise is contacted by a malevolent spirit that tricks her into releasing it into the world, resulting in the murder of Elise’s mother and creating a permanent rift between her and her father.

The ending of ‘The Last Key’ directly sets up the main ‘Insidious’ film, where Elise receives a call from Lorraine Lambert asking for help with her grandson Dalton. This connection allows fans to grasp Elise’s backstory before her return in the original ‘Insidious.’

‘Insidious: The Red Door’ completes the chronological puzzle in an unexpected manner. Although it premiered in 2023, it is a direct sequel to ‘Chapter 2,’ which was released a decade earlier in 2013, and the story is set in 2019, nine years after the terrifying events of the first two films. The film follows both Josh and a college-aged Dalton as they attempt to live a normal life after having their memories of the Further erased at the end of ‘Chapter 2.’

‘Insidious: Out of the Further’ is an upcoming American supernatural horror film written and directed by Jacob Chase, serving as a sequel to ‘Insidious: The Red Door’ and the sixth installment in the franchise. It stars Amelia Eve, Brandon Perea, and Maisie Richardson Sellers, with Lin Shaye reprising her role from the previous films.

In ‘Insidious: Out of the Further,’ Amelia Eve plays Gemma, a young mother raising her daughter in her childhood home who discovers she can travel into the Further, the purgatorial realm of lost souls central to the ‘Insidious’ universe. When something evil pursues her, Gemma uncovers an ability that changes everything; she can not only enter the Further but also bring its inhabitants back into the real world. Once the demons realize her power, our world becomes their playground.

The franchise’s box office success only heightens the stakes for this new chapter. Having amassed over 740 million dollars at the global box office across five films, the chilling franchise is making its return to the big screen as one of the most anticipated horror movies of the year. The film is set to release on August 21, 2026, distributed by Sony Pictures Releasing.

With ‘The Red Door’ already being the top-grossing entry, the pressure is on for ‘Out of the Further’ to demonstrate that Elise Rainier and the mythology of the Further still possess plenty of terror to offer. With a new family at the center of the haunting and a returning icon guiding them, this feels like a true test of whether the franchise can continue to evolve without losing its original scare factor. Are you more excited to see Gemma’s new abilities unfold, or would you prefer the story to circle back to the Lamberts one more time?
