As the series looks to head in new directions, Insidious: The Red Door star Lin Shaye weighs in on the sequel seemingly ending the horror franchise. The next installment in the Leigh Whannell and James Wan-backed franchise will see Patrick Wilson and Ty Simpkins return as Josh and Dalton Lambert, with the story picking up a decade after Insidious: Chapter 2 when they had their memories wiped to forget about the Further. As they venture to drop Dalton off at college, the two are confronted by the literal demons of their family's past for one final haunting chapter.
