HBO Reveals Harry Potter Series Cast, Filming to Begin with On-Set School

HBO is developing a new Harry Potter television series set to premiere in 2026, with production beginning at Warner Bros. Studios Leavesden. The lead roles of Harry, Hermione, and Ron have been cast with young British actors Dominic McLaughlin, Arabella Stanton, and Alastair Stout, respectively, selected for their ability to embody the spirit of the books in a planned ten-year adaptation. To accommodate the lengthy filming schedule, the child actors will receive their education on-site through a specialized "mini-school" at the studio, balancing lessons with their acting commitments. Meanwhile, the original Harry Potter film series famously cast Robbie Coltrane as Hagrid before selecting the actors for the main trio, a decision strongly supported by J.K. Rowling. Additionally, the successful Hogwarts Legacy video game is set to release on Nintendo's new Switch 2 console, with Hogwarts Legacy 2 rumored to be in development though not yet officially confirmed. These developments reflect the continuing expansion of the Harry Potter franchise across multiple media.
