HBO is taking us back to where IT all began with Welcome to Derry, a nine-episode series that will serve as a prequel to Andy Muschietti’s IT films.

Based on Mike Hanlon’s interludes from Stephen King’s novel, which document catastrophic events from the Maine town’s past, IT: Welcome to Derry kicks off in 1962 in the time leading up to the events of IT: Chapter One. The series premieres on HBO Max in October 2025.

Andy Muschietti, who directs multiple episodes of the series, has teased that second and third seasons, if ordered by HBO, would take place in 1935 and 1908, respectively.

Taylour Paige (Beverly Hills Cop: Axel F), Jovan Adepo (The Stand), Chris Chalk (Gotham), James Remar (Dexter), Madeleine Stowe (Revenge), and Stephen Rider (Daredevil) star in the series, with Bill Skarsgård returning as Pennywise the Clown.

Alixandra Fuchs (Boogeyman Pop), Kimberly Guerrero (Reservation Dogs), Dorian Grey (Star Trek: Discovery), Thomas Mitchell (Spiral: From the Book of Saw), BJ Harrison (Rise of the Planet of the Apes), Peter Outerbridge (Saw VI), Shane Marriott (Fargo), Chad Rook (Resident Evil: Welcome to Raccoon City), Joshua Odjick (The Long Walk), Rudy Mancuso (The Flash), and Morningstar Angeline (Echo) round out the cast.

Jason Fuchs (Ice Age: Continental Drift), who wrote the teleplay for the first episode of IT: Welcome to Derry, and Brad Caleb Kane (Crystal Lake) serve as co-show runners.
