Everything We Know About IT: Welcome to Derry Season 2

HBO hasn’t officially confirmed a second season of Welcome to Derry, but it’s definitely happening. Seasons 2 and 3 will serve as prequels to the IT movies from 2017 and 2019, delving deeper into the town’s frightening past. The show won’t be based on a specific Stephen King story, but it will expand on the world established in his 1986 novel, filling in missing pieces of the history.
