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. Now that viewers know just how much the series connects to both IT and King's other novels, it's time to meet the kids and adults set to take on the entity in the horror series. Below, read on for everything we know about the cast of It: Welcome to Derry as of episode 1, "The Pilot."

It: Welcome to Derry kicks off with the disappearance of Matty, a 12-year-old boy who still uses a pacifier and likes to sneak into movie screenings. Fleeing a troubled home life, Matty comes across trouble as he tries to run away from his deadly hometown.

Miles Ekhardt is a child actor who made his professional debut last year, with his role as Davis's younger brother Noah in Turtles All the Way Down.

Leroy's wife Charlotte Hanlon was active in the civil rights movement in Louisiana, where the Hanlons lived before moving to Derry. Per Gizmodo, "Derry has its share of injustices that catch Charlotte’s interest, and it’s hard for her to resist speaking up for what’s right."

Taylour Paige, 35, grew up a dancer in Inglewood, California, including stints training under Debbie Allen and performing as a Laker Girl. She has previously appeared in movies including White Boy Rick, Zola, Boogie, Ma Rainey's Black Bottom, Sharp Stick, and Beverly Hills Cop: Axel F.
