"Production has commenced on the HBO Original Harry Potter television series at Warner Bros. Studios Leavesden, UK. The series will debut in 2027 on HBO and HBO Max where it's available, including in upcoming launch markets Germany, Italy, and the UK."
Harry Potter creator J.K. Rowling will be an executive producer of the project alongside Neil Blair and Ruth Kenley-Letts from Brontë Film and TV and David Heyman from Heyday Films. Succession and Game of Thrones director Mark Mylod will also be an executive producer for the series, and he will also be directing some episodes, per Warner Bros. Discovery.
The new TV series will reportedly feature one of the seven Harry Potter books per season, according to Variety. The outlet also mentioned that shooting for the show's debut season is expected to finish sometime in the spring of 2026, followed by a short break before the cast and crew return to start filming the second season.
