In March 2022, HBO and Warner Bros. announced a prequel series to the IT franchise. The prequel will be titled, "Welcome to Derry". The director of the two earlier films, Andy Muschietti, will work as an executive director on the series with his sister, Barbara Muschietti.
Filming in Port Hope, Ontario, Canada.
The show began filming in May 2023 despite the 2023 Writers Guild of America Strike taking place around the same time. Writing for the show was already completed before the strike.
The show is a prequel series to director Andy Muschietti's It (2017) and It Chapter Two (2019). It explores the origins of Pennywise/It.
The show is scheduled to air on HBO Max in 2024.
