10 Things You'll Only Notice in the It Remake If You Read the Book

While the Losers are knee-deep in their sewer fight with Pennywise, we see a whole barrage of crazy forms that It can take. This is because It is surrounded by children, so It's trying to capture all their different fears at once. If you pay close attention, you can also see a couple of giant spider legs jut out and dig into the ground.

This is a nod to It's final form, which is a gigantic, hairy female spider. At least, that's how the Losers Club perceives It once all the other forms are stripped away. While we don't get to see this terrifying form in all its glory, you can bet a giant spider is coming in the sequel.
