The Malfoys Enter the Frame
One of the most notable announcements is the casting of Draco Malfoy. Young actor Lox Pratt will get to play Harry Potter’s Slytherin classmate and long-time arch-nemesis, a fan-favorite role played by Tom Felton in the original films.
Starring opposite him, award-winning actor Johnny Flynn, best known for his roles in Ripley and The Dig, will portray Draco’s father, Lucius Malfoy. A man characterized by his cold sophistication and pure-blood elitism. Notably, Jason Isaacs, who first played Lucius on screen, has given Flynn his complete endorsement, labeling him a “brilliant actor” and a “lovely man.”
A New Look for the Dursleys
Also on board are new faces for the Dursleys, Harry’s unkind Muggle relatives who adopt him following the death of his parents. Bel Powley (Masters of the Air, The Morning Show) will play Petunia Dursley, and Daniel Rigby (Flowers, Eric & Ernie) will play Vernon Dursley.
This time, the series is keeping the characters younger in line with how they’re presented in J.K. Rowling’s books. It’s a mark of overall commitment to bringing the novels to life with greater faithfulness to the source material.
Welcoming Hogwarts’ Supporting Cast
Hogwarts is also filling out its student body with several key additions. Leo Earley will portray Seamus Finnigan, Alessia Leoni is set to play Parvati Patil, and Sienna Moosah has been cast as Lavender Brown.

While these characters only had brief moments in the original films, their confirmed presence in Season 1 points to a more faithful and fleshed-out adaptation of the book’s ensemble cast, something longtime fans have been hoping for.
Molly Weasley and Cornelius Fudge Join the Story
Katherine Parkinson, best known for roles in The IT Crowd and Rivals, will take on the role of Molly Weasley, the strong, nurturing matriarch of the Weasley family, a part originally portrayed by Julie Walters.
Katherine Parkinson’s early inclusion hints that the Weasley family will play a central role right from the start. On the political side of the wizarding world, Bertie Carvel (Dalgliesh, The Sister) will take on the role of Cornelius Fudge, the often-blundering Minister for Magic.
Previously Announced Main Cast
These newly announced names join a growing cast already confirmed earlier this year. Dominic McLaughlin is set to star as Harry Potter, with Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley.
The adult cast is equally stacked, featuring John Lithgow as Albus Dumbledore, Janet McTeer as Professor McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Professor Quirrell, and Paul Whitehouse as Argus Filch.
A Decade of Magic Ahead
With HBO planning to adapt all seven books across ten seasons, one full season per book, the series aims to deliver a “faithful adaptation” that offers deeper character development and richer storytelling than was possible in the films.
Casting younger actors as the Dursleys is part of the push to stay true to the source material. At the same time, bringing in characters who were often overlooked in earlier adaptations suggests a deeper focus on the story as it was originally written.
Filming is officially underway at Warner Bros. Studios in Leavesden, and the buzz is real. Fans are looking forward to stepping back into Hogwarts, this time with a fresh cast and a version of the story that aims to stick closer to the original books..
