Scheduled to premiere in 2027, the Harry Potter series produced by HBO continues to make progress with an important new update. HBO and Warner Bros. Television have announced that the original music will be composed by Hans Zimmer, in collaboration with the band Bleeding Fingers Music. This news adds another layer to an already well-advanced project, which has revealed a significant portion of its main and supporting cast, with a global release set for 2027 on HBO Max.
Presented as a faithful adaptation of J.K. Rowling’s seven novels, the series is written and produced by Francesca Gardiner (His Dark Materials), with Mark Mylod (Succession) directing multiple episodes. The production is handled by Brontë Film and TV, Warner Bros. Television, and Heyday Films, with direct involvement from J.K. Rowling, Neil Blair, Ruth Kenley-Letts, and David Heyman.
The series follows Harry Potter's journey, a young orphan who discovers he's a wizard at the age of eleven. From his arrival at Hogwarts to his gradually intensifying battle against Voldemort, each season adapts a novel from the saga, expanding on the secondary plots, the relationships between students and teachers, and the political and magical stakes of the world created by J.K. Rowling.
The official trailer will be released as soon as HBO publishes it.
Following an extensive casting campaign led by Lucy Bevan and Emily Brockmann, HBO has cast a fresh new slate of actors in the lead roles. Dominic McLaughlin steps into the shoes of Harry Potter, Arabella Stanton brings Hermione Granger to life, and Alastair Stout portrays Ron Weasley. This trio forms the heart of the adaptation, which is designed to develop over the long term.
The series also boasts an impressive adult cast. John Lithgow takes on the role of Albus Dumbledore, while Janet McTeer portrays Minerva McGonagall. Paapa Essiedu brings Severus Snape to life, and Nick Frost appears as Rubeus Hagrid. Luke Thallon is cast as Quirinus Quirrell, and Paul Whitehouse plays Argus Filch.
The cast expands to include the great families of the saga and Hogwarts students. Katherine Parkinson takes on the role of Molly Weasley, Johnny Flynn portrays Lucius Malfoy, and Lox Pratt plays Draco Malfoy. The Dursleys are brought to life by Bel Powley (Petunia) and Daniel Rigby (Vernon). Among the students are Rory Wilmot as Neville Longbottom, Leo Earley as Seamus Finnigan, Alessia Leoni as Parvati Patil, and Sienna Moosah as Lavender Brown.
HBO has announced the casting of the Weasley children: Tristan and Gabriel Harland will play Fred and George, Ruari Spooner takes on Percy, and Gracie Cochrane will portray Ginny Weasley.
The latest update confirms that the original score will be crafted by Hans Zimmer and the Bleeding Fingers Music team. Together, they will create a distinctive sonic identity tailored to the series format, setting it apart from the films while honoring the franchise’s musical legacy.
In a joint statement, Hans Zimmer, Kara Talve, and Anže Rozman emphasize the cultural significance of the Harry Potter universe and express their commitment to delivering a fresh, innovative approach designed to develop characters and storylines across multiple seasons.
Each season will cover one academic year at Hogwarts, allowing for a deeper dive into the novels beyond what the movies could offer. This format gives the series space to expand its storylines, explore richer themes, and fully immerse viewers in its visual and soundscape like never before.
