The Insidious franchise will continue to bring The Further’s horror to the big screen with yet another sequel. Honestly, anyone who watched Insidious: The Red Door isn’t shocked after that post-credits scene with the light flickering over that door of terrors. The next Insidious installment will once again come from Blumhouse Productions and hit theaters on August 29, 2025.

Of course, there are no other details at this time. We don’t know if we will see the Lambert family again or if the Insidious franchise will branch off in another direction. But, thanks to Variety, we do know that this sequel will not have any ties to Thread: An Insidious Tale, which is an in-universe spinoff series that will star Mandy Moore and Kumail Nanjiani. We will have to wait and see what The Further offers us next.
