New Faces Join HBO's Ambitious Harry Potter Reboot
HBO’s new Harry Potter TV series just got a lot more interesting. After months of speculation and an extensive worldwide casting call, studio heads have revealed an expanded cast lineup set to bring J.K. Rowling’s wizarding world to life for a whole new generation.
The core trio is officially set with Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout rounding it out as Ron Weasley. That announcement alone sparked a frenzy among Potterheads worldwide, with many noting that the casting team sifted through tens of thousands of hopefuls before zeroing in on this group.
But it’s the addition of beloved supporting characters that’s really getting people talking. Molly Weasley—a mother figure for so many readers—will be played by Katherine Parkinson, known for her mix of warmth and sharp wit on screen. If you’ve ever watched her in a TV comedy or drama, you know she can switch effortlessly from gentle to formidable, which suits Molly perfectly.
John Lithgow is stepping in as Dumbledore, while Janet McTeer will bring a no-nonsense vibe to Professor McGonagall. Fans are particularly curious about Nick Frost as Hagrid, whose easygoing humor could make him a natural fit for the role.

The Wizarding World Expands: Malfoys, Dursleys, and More
Turning to Hogwarts’ less-friendly faces, Lucius Malfoy will be portrayed by Johnny Flynn, and Lox Pratt is set as Draco—a dynamic to watch for, given their pivotal moments throughout the series. Cornelius Fudge, the bumbling Minister of Magic, will be played by Bertie Carvel, a performer with a knack for giving complex, sometimes disgraced, authority figures a human edge.
Fans who love to hate the Dursleys can look forward to Daniel Rigby as Vernon and Bel Powley as Petunia. Their on-screen banter should make early Harry Potter scenes as awkward—and memorable—as people remember from the books.
On the student front, Leo Earley takes on Seamus Finnigan, Alessia Leoni steps in as Parvati Patil, and Sienna Moosah becomes Lavender Brown. Each one forms part of the rich Hogwarts tapestry, ensuring those side stories have plenty of life.
The showrunner Francesca Gardiner and director Mark Mylod have both spoken out about just how competitive the casting process was. They say these new stars bring fresh energy and surprising depth to roles that fans thought they already knew inside out.
But the story isn’t complete yet. There’s still buzz over who will play other key Hogwarts names—like Neville Longbottom, Ginny Weasley, and the mischievous Weasley twins. Those roles are expected to be announced soon, promising more excitement for Potter fans counting down until production finally begins.
