The Insidious franchise continues with its fifth installment, Insidious: The Red Door, and while Insidious 6 news may not be on the horizon, there are some big plans in the works for the remainder of the series. Horror director James Wan found that he had another thrilling hit on his hands when Insidious was released to the public in 2011, introducing to the world to the Lambert family, led by parents Josh (Patrick Wilson) and Renai (Rose Byrne), and the spirits that continued to haunt them and their son Dalton (Ty Simpkins). While the third and fourth movies branched outside of the Lamberts, Insidious 5 returned to their family.
