The cast of Part Two of "It" has been named. Jessica Chastain, hubba hubba. Bill Hader as Richie! Lol. And McAvoy is always interesting. Director Andy Muschietti was on hand to introduce the footage, along with most of the Losers' Club, old and young, including Sophia Lillis and Jessica Chastain as Beverly, Finn Wolfhard and Bill Hader as Richie, and James McAvoy as Bill.
