It – Welcome to Derry

It: Welcome to Derry is an American supernatural horror television series based on Stephen King's 1986 novel It. Serving as a prequel to the films It (2017) and It Chapter Two (2019), the series was developed by Andy Muschietti, Barbara Muschietti and Jason Fuchs, all of whom were involved in the It films. The series stars Taylour Paige, Jovan Adepo, Chris Chalk, James Remar, Stephen Rider, Clara Stack, Amanda Christine, and Mikkal Karim-Fidler, with Bill Skarsgård reprising his role as Pennywise from the films and serving as an executive producer on the series.

Andy and Barbara Muschietti along with Fuchs began developing an It television series in March 2022. After receiving a production commitment later that November, Fuchs and Brad Kane were hired as showrunners. The series was greenlit in February 2023, with Andy Muschietti attached to direct multiple episodes, including the pilot episode, and Fuchs as a writer. Casting began later in April, including Skarsgård being cast in May 2024. Filming for the series began in May 2023 but was halted in July due to the 2023 SAG-AFTRA strike; it concluded in August 2024.

It: Welcome to Derry premiered on HBO on October 26, 2025. The series received generally positive reviews from critics for its production value, direction, opening title sequence, and performances (particularly those of Skarsgård, Chalk, and the younger actors), but received criticism for its visual effects and some writing choices.
