To add even more fuel to the fire, I’m sure they’re looking for that paranormal IP in succession to Insidious being HoTY and this would likely be Hollywood’s exclusive IP. Historically post-Covid, Hollywood has always liked to have an exclusive be a repeat or returning IP. Evil Dead Rise is the exception but that’s simply because it was built upon an already built house.
So yeah, Poltergeist isn’t my first choice, but I can totally see it happen. If they can’t get the Conjuring to fulfill that paranormal spot, I guess that’s the best they can do.
