Should that be the case, maybe it might be a good idea to film even more additional material, and re-edit the entire series into a three-film opus after all.
It’s going to probably be a while before the two halves of IT and IT Chapter Two are made into one cohesive whole.
Even in that event, there’s a chance that this adaptation of the story Stephen King [committed to paper in 1986](https://en.wikipedia.org/wiki/It_(novel) might still feel a little lacking.
