HBO’s Harry Potter Series: New Cast & Details Revealed

Creative Leadership & Production Team

At the helm of this ambitious project is showrunner and head writer Francesca Gardiner, known for her work on Succession and His Dark Materials. Gardiner brings a wealth of experience in crafting complex narratives, ensuring a deep and nuanced exploration of the Wizarding World. Director Mark Mylod, also a veteran of Succession, is set to direct multiple episodes, bringing his sharp directorial vision to the series. The production is a collaboration between HBO Entertainment, Warner Bros. Television, Brontë Film & TV, and Heyday Films. Executive producers include Neil Blair, Ruth Kenley-Letts, Gardiner, Mylod, and David Heyman, who produced the original film series.

Additionally, J.K. Rowling serves as an executive producer on the series and has been actively involved in the development process. She has reviewed scripts for the first two episodes and expressed her approval, stating they are "so, so, so good." While she is not writing the episodes herself, Rowling has worked closely with the writers to ensure the adaptation remains faithful to the original material.

Filming for the first season, which will cover Harry Potter and the Philosopher's Stone, began in July 2025 and is expected to continue through April 2026. Subsequent seasons will follow a similar production timeline, with each season adapting one book from the series. The series aims to provide a more detailed and faithful adaptation compared to the original films, allowing for deeper character development and exploration of the magical world.
