When we met the titular character in Stephen King’s IT, he was a clown living in a sewer. As it turns out, the character has a backstory that was filmed and left on the cutting-room floor. Bill Skarsgård, who played IT, hints as to what it is.
Skarsgård told Variety,
There was a scene we shot that was a flashback from the 1600s, before Pennywise [was Pennywise]. The scene turned out really, really disturbing. And I’m not the clown. I look more like myself. It’s very disturbing, and sort of a backstory for what It is, or where Pennywise came from. That might be something worth exploring in the second one. The idea is the ‘It’ entity was dormant for thousands and thousands of years. The [flashback] scene hints on that.
I think that could be cool to explore as well. It’s like, what is Pennywise? He only exists in the imagination of children. If you don’t believe him to be real then he might not be real. There’s an interesting aspect to explore there.
That’s not how Stephen King wrote it. In the novel, IT comes from the void that surrounds the universe, called the Macroverse. IT is a multi-dimensional being made of writhing orange “deadlight” and pure evil.
Having Skarsgård appear as a human hints that IT took a human body as its own. But as readers know, IT never used a human as a meat puppet, because it could create its own form whenever it wanted to.
Here’s hoping we’ll see the scene in question on the DVD/Blu-ray extras, or in the upcoming second. Here’s hoping even harder we’ll learn what Stephen King thinks of this.
