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 a large ensemble cast including Bill Skarsgård, who serves as executive producer and reprises his role as Pennywise from the films.

Andy and Barbara Muschietti along with Fuchs began developing the series in March 2022. After receiving a production commitment later that November, Fuchs and Brad Kane were hired as showrunners, and the series was greenlit in February 2023, with Andy Muschietti, who had directed both films, attached to direct multiple episodes, including the pilot. Casting began later in April, with Skarsgård 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.
