Insidious: Chapter 2 seemingly ended the story of the Lambert family, but with Insidious 5 in the works, it's time to bring them back into the fold. With the 2011 release of Insidious, director James Wan managed to create his second hit horror franchise, after first creating the Saw series. Like Saw, the Insidious movies would show a knack for being what studios love the most: movies with low budgets that go on to make enough profit to fill a large yacht.

The four Insidious movies made to date have raked in $555 million worldwide, on budgets that have never topped the $10 million mark. That's a profit margin anyone would be jealous of, and Insidious served as one of the first franchises to really establish Blumhouse Productions as the powerhouse it currently is within the world of Hollywood horror. With 2018's Insidious: The Last Key earning the highest overall gross in the series to date, it makes perfect sense that Insidious 5 would be on the agenda sometime pretty soon.

Blumhouse has yet to officially announce that an Insidious 5 is happening, but there have been rumblings of the project kicking off since not long after The Last Key's release. For her part, series star Lin Shaye said back in November that she had heard there would be another sequel. If it happens, it's time to bring back the Lamberts.

How Insidious 5 Could Bring Back The Lambert Family

Insidious: Chapter 2 was designed from the start to wrap up the case of the Lambert family, who had been besieged by a demonic entity, and later had patriarch Josh Lambert (Patrick Wilson) possessed by the malevolent spirit of a serial killer. Josh and his son Dalton had their memories of the traumatic experience suppressed, and things looked to be smooth sailing. Of course, psychic Elise Rainer also ended up dead, but the franchise continued by giving her the spotlight in prequels set before the original film.

Lin Shaye herself has said that Insidious: The Last Key brought Elise's story full circle, and that as far as she knows, an Insidious 5 will be a sequel to Insidious: Chapter 2, in the sense that it takes place afterward. Shaye also said, while revealing little, that the idea she'd heard broached for Insidious 5 involved some past characters. With that in mind, Insidious 5 would be the perfect opportunity to bring the Lamberts back. Why would they reenter the story after Chapter 2's ending? Because they still have a loose end.

At the end of Insidious: Chapter 2, Elise's ghost accompanies Specs and Tucker to a new case. While there, she sees an entity that frightens her, and most fans believe that entity to be the Lipstick Face Demon that haunted the Lamberts and abducted their son Dalton in the first film. The creature had never been truly defeated, just temporarily made unable to enter the mortal world through Dalton. If it found another way back from The Further, the demon could choose to try and get revenge on the Lamberts for its prior defeat, necessitating that they have their memories of the first two movies restored in order to defend themselves. Elise's ghost could also assist the Lamberts once again from The Further. Wilson says he's open to reprising Josh in Insidious 5, so if Rose Byrne can be convinced to return as Renai, it could be time for the darkest of family reunions.
