The premiere episode garnered 5.7 million viewers within three days of viewing the U.S., according to multiplatform viewing data across HBO and HBO Max. This gave “It: Welcome to Derry” the third most-watched series debut on HBO Max, behind only “Game of Thrones” spinoff “House of the Dragon” and “The Last of Us.”

Set in the world of Stephen King’s “It” universe, the series expands the narrative from feature films “It” and “It Chapter Two,” both helmed by Andy Muschietti. Andy Muschietti, Barbara Muschietti and Jason Fuchs developed the prequel for television.
