As we reported earlier, there is a component of interdimensional storytelling that it pivotal to IT, and it likely is being saved for the second chapter.
Ignoring the adult storyline isn’t the only major change Andres Muschiettit is making to his adaptation.
Now, we just need WB to go ahead and greenlight the sequel (we know it’s happening!) so that proper plans can be made and casting can get underway.
IT takes place in two time periods, when kids band together to confront the ultimate evil, and then must reunite years later to readdress the issue after the threat returns.
