Oh, snap! What a delightful piece of casting news. As we learned earlier today, IT: Chapter 2 is rolling into production this summer, and as expected, the casting is rolling in quick. THR reports that X-Men star James McAvoy and SNL vet Bill Hader are in talks to join the film.

Hader has been a fan-casting favorite for the part as adult Richie Tozier since audiences saw Finn Wolfhard‘s portrayal in the first film, and guess what, not everything is terrible, sometimes dreams come true, and Hader might just end up in the role. That excellent news is matched by the unexpected but equally welcome word that McAvoy is in negotiations to play the adult Bill Denbrough. Jaeden Lieberher played the character in the first film as the young, stuttering leader of the Losers who discovers the ancient evil in Derry, Maine while hunting for his missing brother.

If the deals close, McAvoy and Hader would join Jessica Chastain, who is on board to play Beverly Marsh, originated in the first film by scene-stealer Sophia Lillis. It: Chapter 2 will reunite Chastain with director Andy Muschietti and producer Barbara Muschietti, who previously worked with the Oscar-nominated actress on the 2013 ghost story Mama. Hader, McAvoy and Chastain all previously worked together on The Disappearance of Eleanor Rigby. In addition to the adult cast, the young actors from the first film are expected to reprise their roles for flashbacks alongside Bill Skarsgård as Pennywise the Clown.

The sequel will pick up with the Losers 27 years after the events of the first film, when the memories of their traumatic summer start returning and they’re forced to head back to Derry to do battle with evil once again. Screenwriter Gary Dauberman, the New Line favorite who reworked Cary Fukunaga and Chase Palmer’s original script for Chapter 1, is returning to write the script. Producers Dan Lin and Roy Lee and executive producers Seth Grahame-Smith and David Katzenberg are also returning.

Chapter 2 is scheduled to head into production this July before arriving in theaters on September 6, 2019.
