The highly anticipated Harry Potter series by HBO has made a substantial advancement with the appointment of its showrunner and director. Francesca Gardiner, recognized for her contributions to HBO's Succession and His Dark Materials, will take on the roles of writer and showrunner. Mark Mylod, celebrated for his direction in Game of Thrones and Succession, will direct several episodes. Both Gardiner and Mylod contribute their Emmy-winning expertise to the project. Gardiner's background includes producing Killing Eve and The Rook, while Mylod has directed for The Last of Us and Shameless. Initially planned for HBO Max, the series is now positioned as an HBO original, reflecting Warner Bros. Discovery's content strategy, as reported by The Hollywood Reporter. This change means the series will broadcast on the cable channel and stream on HBO Max. Touted as a 'faithful adaptation' of JK Rowling's popular fantasy series, it will feature a new cast to guide a fresh audience through the magical realms of Hogwarts and its captivating characters. Details on casting for roles previously played by Daniel Radcliffe, Emma Watson, and Rupert Grint will be announced later. Warner Bros. Discovery CEO David Zaslav targets a 2026 launch for the series, aiming to preserve the spirit of Rowling's literary world while exploring new narrative avenues on screen. Executive producers include Rowling, Neil Blair, Ruth Kenley-Letts from Bronte Film and TV, and David Heyman, producer of the original Harry Potter film series. Warner Bros. Television and Bronte Film and TV will handle production.
