As mirrored so far in director James Wan’s first two Conjuring movies, the real investigations of Ed and Lorraine Warren primarily focused on demonic hauntings of people, places and things — but there is some variety in their case history that could change things up on the big screen.
For example, Ed Warren published the book Werewolf: A True Story of Demonic Possession back in 1991.
James Wan is currently working on Aquaman as his next big project, and that’s going to keep him busy for the foreseeable future.
