Over a decade after the Lambert family first drew the attention of the unspeakable things that lurk in The Further, Insidious: The Red Door updates reveal a final terrifying chapter to the franchise. The Blumhouse horror franchise kicked off in 2010 with James Wan's modern now-cult supernatural horror classic Insidious, a relatively cheap production that raked in big money at the box office. The 2013 sequel Insidious: Chapter 2 was even more successful, while a subsequent prequel and a fourth franchise installment demonstrated that horror fans can't get enough. In 2023 Insidious 5, titled Insidious: The Red Door, will once again put the Lambert family directly in the sights of the abyssal menace that is the Red-Faced Demon.
