The first cast photo for It: Chapter 2 has been released during a group script reading. Production started Monday for the sequel to the 2017 film adaptation of Stephen King’s “It,” the highest grossing horror film of all time with more than $700 million worldwide.

The follow-up will be in theaters Sept. 6, 2019.

We learned in “It” that evil revisits the town of Derry, Maine, every 27 years. So “Chapter Two” brings the characters — who’ve long since gone their separate ways —back together as adults, nearly three decades after the terrifying events of their childhood.

Naturally, this means the terrifying clown Pennywise (Bill Skarsgård) is back. James McAvoy stars as grown-up Bill, Jessica Chastain as Beverly, Bill Hader as Richie, Isaiah Mustafa as Mike, Jay Ryan as Ben, James Ransone as Eddie, and Andy Bean as Stanley.
