Harry Potter TV series confirmed for 10-year HBO Max run with eight-episode first season

Warner Bros. Discovery confirms Harry Potter TV series will span decade on HBO Max, set for 2027 premiere.

Warner Bros. Discovery CEO David Zaslav confirmed the upcoming Harry Potter TV series will run for a decade on HBO Max, exceeding the initially expected seven-season format based on J.K. Rowling’s books. Speaking during the company’s latest earnings call, Zaslav highlighted the project’s long-term vision as production for Season 1 continues in and around London. The series is scheduled to premiere in 2027, Collider reported.

Early promotional material has already revealed Dominic McLaughlin as Harry Potter, Nick Frost as Hagrid, and Daniel Rigby and Bel Powley as Uncle Vernon and Aunt Petunia. The core trio will feature Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley. Legendary actors join the Hogwarts staff, including John Lithgow as Dumbledore, Paapa Essiedu as Snape, and Janet McTeer as McGonagall, with other notable roles played by Johnny Flynn, Louise Brealey, Anton Lesser, Luke Thallon, Paul Whitehouse, and Rory Wilmot.

Beyond the cast, the production team includes acclaimed Brazilian cinematographer Adriano Goldman, known for The Crown, Andor, and Jane Eyre, who will serve as lead director of photography for Season 1. Goldman confirmed the season will include eight episodes—contrary to earlier rumors of six—with him handling the first two and final two episodes. He described the season as “monumental,” noting 18 weeks of pre-production were spent building lasting sets for Hogwarts, Privet Drive, and other iconic locations.

Zaslav’s decade-long commitment has fueled speculation about whether future seasons might split books into multiple parts or include original material. Goldman noted there is “a prospect of seven seasons,” though his involvement in all remains uncertain.

Filming for Season 1 is expected to last 10 months and may also cover portions of Season 2. With its 2027 premiere planned, HBO Max is positioning Harry Potter as a long-term flagship franchise.
