In addition to Andy Muschietti returning as executive producer and director, his sister, producer Barbara Muschietti, continues as a series creator and executive producer. Bill Skarsgård is also set to reprise his iconic role as Pennywise the Clown. "Wonder Woman" co-writer Jason Fuchs and "Tokyo Vice" co-writer Brad Kane serve as showrunners for the entire series.

"Welcome to Derry" draws inspiration from interstitial stories within Stephen King's original novel, exploring the origins of Pennywise. The series is planned for at least three seasons, with the first season set in 1962, the second in 1935, and the third in 1908, tracing the entity's history backward.
