On the Sunday before Halloween, It: Welcome to Derry arrived on HBO to extend Spooky Season into the holidays. Developed by the minds behind It and It: Chapter Two, HBO's original prequel series returns viewers to Derry, Maine, 27 years before the events of the 2017 and 2019 film adaptations of Stephen King's iconic novel. Set in 1962, Welcome to Derry takes place during an earlier active cycle where IT (the shapeshifting evil that sometimes appears as Pennywise) awakens to terrorize and feed on the town's children.
Ahead of Welcome to Derry's debut on October 26, 2025, HBO kept character and plot details under wraps, to hide the new series's extensive connections to both IT and King's other novels. With the season finale airing on December 14, it's time to learn more about the kids and adults who take on the entity in the horror series. Below, read on for everything we know about the cast of It: Welcome to Derry.
