HBO has confirmed that the upcoming Harry Potter TV series has been renewed for a second season, with filming scheduled to begin in fall (September – December) this year. The first season, Harry Potter and the Philosopher’s Stone, is set to premiere this Christmas on HBO Max.
While the network has not announced an official title, it is widely believed that the second season will adapt The Chamber of Secrets, the second book in J.K. Rowling’s franchise.
Jon Brown, who worked on the first season as a writer and is known for his work on Succession, has been promoted to co-showrunner alongside Francesca Gardiner, who led season one. HBO has previously announced plans to adapt all seven books over the course of a decade, with each season covering one instalment.

According to BBC, Gardiner said the return to filming this fall is part of “overlapping production schedules” as season one wraps. She added that bringing Brown on board as co-showrunner was “key to maintaining our momentum.” Gardiner also serves as executive producer alongside director Mark Mylod, also known for his work on Succession.
The first season will follow Harry’s first year at Hogwarts, introducing audiences to the magical world while exploring his identity as a wizard. The first trailer, released in March, featured beloved moments from the books, iconic set pieces, and glimpses of central characters. Dominic McLaughlin, Arabella Stanton, and Alastair Stout were cast as Harry, Hermione, and Ron respectively.
No premiere date has been set for season two. The Chamber of Secrets will take Harry and his friends deeper into the mysteries of Hogwarts, confronting dangerous creatures and old enemies.
