HBO has confirmed that its upcoming Harry Potter television series will premiere in December 2026, with production already underway at Leavesden Studios since July 14, 2025. The series, which will adapt all seven books by J.K. Rowling, is expected to run for 10 consecutive years, according to HBO & Max Content Chairman and CEO Casey Bloys.
The main trio has been cast: Dominic McLaughlin as Harry Potter, Alastair Stout as Ron Weasley, and Arabella Stanton as Hermione Granger. Gracie Cochrane, who was originally cast as Ginny Weasley, has left the series due to unforeseen circumstances, and the role will be recast for Season 2. The series has already been renewed for a second season, with Jon Brown joining Francesca Gardiner as co-showrunner.
Francesca Gardiner, a consulting producer on Succession, won the showrunner role after beating out Tom Moran and Kathleen Jordan. Mark Mylod, who worked with Gardiner on Succession, will direct multiple episodes and serve as executive producer. Oscar-winning costume designer Holly Waddington (Poor Things) is also attached to the project.
Chris Columbus, director of the first two Harry Potter films, has praised the television reboot as a “spectacular idea.” The series will be a faithful adaptation of the books, with each season reportedly focusing on one novel, though Bloys has suggested the timeline may allow for more flexibility. The Fantastic Beasts franchise will not be part of this series.
