After the massive box office success of IT, New Line Cinema isn’t messing around in adding some massive names to the cast of the sequel, which is to begin filming this July.

With Jessica Chastain officially on board It: Chapter 2, New Line has now begun to zero in on who will play the rest of the Losers Club with James McAvoy (Split, Glass, X-Men) and Bill Hader (pictured below in the HBO series “Barry”) in talks to join the next installment, reports Variety.

McAvoy is in talks for the role of Bill, who was played by Jaeden Lieberher in the first pic, while Hader is in talks for the role of Richie, which was played by Finn Wolfhard in the last film. As previously announced, Chastain will play Beverly.

Director Andy Muschietti is back to direct, with Gary Dauberman penning the script.

Sources stress that negotiations are early and that the script is still being worked on, but both sides have officially begun discussing her coming on to the project. Bill Skarsgard is also expected to return as Pennywise.

Chapter One of It followed the first half of Stephen King’s eponymous novel, telling the story of a group of children who are terrorized by Pennywise the Clown and forced to face their own demons to defeat him. Chapter Two will follow the last half of the novel, when the characters return to their hometown years later as adults to face Pennywise once again.

Pennywise brings out the balloons on Sept. 6, 2019.
