Joining Dominic McLaughlin as Harry Potter is Alastair Stout as Ronald Weasley and Arabella Stanton as Hermione Granger.

The young cast, who were recently spotted filming at London Zoo, will be receiving education in a purpose-built school on the set.

Newly announced cast includes Rory Wilmot as Neville Longbottom, Amos Kitson as Dudley Dursley, Louise Brealey as Madam Rolanda Hooch, and Anton Lesser as Garrick Ollivander. 

The upcoming series is written and executive produced by Francesca Gardiner. Mark Mylod will executive produce and direct multiple episodes of the series for HBO in association with Brontë Film and TV and Warner Bros. Television. The series is executive produced by J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV and David Heyman of Heyday Films.

Harry Potter TV Series will debut in 2027 on HBO and HBO Max.
