HBO has officially scheduled It: Welcome to Derry to premiere on October 26 of 2025, a timing that seems custom-built for spooky-season viewing. The streamer and cabler will launch the first episode in the week before Halloween, with the nine-episode season then rolling out on a weekly basis.
What the series is — and where it sits in the timeline
It: Welcome to Derry serves as a prequel to the 2017 film It and 2019’s It Chapter Two. Instead of retelling the Losers Club story, the show follows a different group of kids who confront Pennywise roughly 27 years before the events seen in the films. Reports indicate HBO plans to air the premiere simultaneously on its cable channel and on the HBO Max streaming service, making it a multiplatform launch timed for the Halloween season.
A deliberate crossover strategy — ties to The Shining, Shawshank and beyond
Andy Muschietti and his collaborators have said the series is designed to open windows into other King stories, not just retell one novel. Trailers and commentary have already teased familiar landmarks: Shawshank Penitentiary appears as a meaningful location, and the show introduces a younger Dick Hallorann — the character King fans know from The Shining. Casting-wise, actor Chris Chalk takes on that younger Hallorann, which brings the “shining” psychic legacy into the It continuity in a new way. Muschietti has framed those choices as purposeful: the series won’t merely allude to other titles but will give viewers tangible connections and glimpses of “the other side,” widening the scope of the story beyond Derry’s obvious horrors.
The Dark Tower and the macroverse angle
One of the more ambitious aspects the team teases is the show’s nod to The Dark Tower and the larger King macroverse. Muschietti has suggested that the forces behind Pennywise and other supernatural elements tie into the same overarching reality that The Dark Tower inhabits. Expect the series to show those links from a human point of view — it will remain an It story at heart, but with more explicit signals that these events belong to something vaster. Whether other contemporary takes on King properties — for example, different filmmakers’ versions of The Dark Tower — will be folded in remains speculative, but the series clearly intends to invite that larger conversation.
Why the timing and rollout matter
Dropping the premiere in the days before Halloween is smart programming: horror performs strongly in late October, and a serialized, weekly release lets buzz build across the month. By staging the debut on both HBO’s linear channel and its streaming platform, the network positions It: Welcome to Derry to reach traditional TV viewers and binge-hungry streamers alike. Given the enduring popularity of Pennywise and the curiosity around King’s interlinked worlds, the series looks poised to attract a broad, passionate audience.
What to expect (and what remains to be seen)
Viewers can expect a season that balances a contained Pennywise story with Easter eggs and connective tissue to other King works — Shawshank and The Shining already appear to play active roles, and the series promises more overt nods to the macroverse. The human perspective stays central: Muschietti emphasizes storytelling through the people of Derry even as the world behind them expands. The exact degree to which It: Welcome to Derry will alter or redefine King’s continuity is still unknown, but the creative team clearly intends to use the series format to explore backstory, character, and cosmic connections in a way the films only hinted at.
