Jessica Chastain just finished her scenes. EDIT: OH!! Adult Beverly's big scene in the book is the gingerbread house witch! That gets R rated as fuck, I hope it stays in uncut.
It Chapter 2 is doing the ritual of Chud! I think I said it somewhere earlier up-thread, the book version of their final battle with IT is like an R rated version of Dr. Strange in Dormammu's realm. I'm glad they're attempting it, and I can't wait to see WTF they make it look like. http://www.darkhorizons.com/it-chapter-two-includes-ritual-of-chud/
My only previous knowledge of IT was the T.V version with Tim Curry so I'm glad that they are adding more elemants from the book that I haven't seen.
