On the way from HBO Max is a Pennywise the Clown origin story titled Welcome to Derry, which will serve as a prequel series to the two Stephen King It movies from Andy Muschietti. The streamer’s Head of Originals, Sarah Aubrey, told Variety what to expect from the upcoming horror series.

“We have been working with Jason Fuchs, Brad Caleb Kane, Andy Muschietti and Barbara Muschietti very closely,” Aubrey says. “They’re so deep into this mythology and they have such a firm handle on the storytelling around these characters and also the demented scares that they’re putting into things. Sometimes I’m, like, ‘What’s wrong with you?’ Just all the wild ways they think up to terrify us. You’ll be hearing more concretely about that development very soon… Andy is very involved in every bit of this, so that is the real recipe for success and for delighting fans.”

Also revealed is that Jason Fuchs (Wonder Woman) and Brad Caleb Kane (Black Sails, Fringe) will serve as co-showrunners on Welcome to Derry. It was previously reported that Fuchs wrote the teleplay for the first episode of the series, based on a story he wrote along with the Muschiettis (Andy, who directed both It films and Barbara, who produced them).

Plot details are still under wraps, but we do know the series will be set in the 1960s in the time leading up to the events of It: Part One, and will include the origin story of Pennywise. Welcome to Derry has yet to receive a release window, but stay tuned for more information as we hear it.
