HBO Harry Potter Series: Harry Potter TV Series: Hogwarts gets new Dumbledore, Snape, McGonagall and Hagrid, but who will play Harry, Hermione and Ron?

The announcement confirmed that the cast selected to portray some of Hogwarts’ most iconic staff, including Dumbledore, Snape, Magnagar and Hagrid – the key figures in the magical legend that have attracted readers and audiences for more than two decades.
The cast update, released by series host Francesca Gardiner and executive producer Mark Mylod, marks a commitment to the streaming platform’s commitment to “faithful adaptation” to produce JK Rowling’s famous books.
Senior performer takes on legendary roles
American stage and screen veteran John Lithgow will serve as the headmaster of Hogwarts and the mantle of Albus Dumbledore, who franchises the Ethical Compass.
Lithgow, 79, called the character a “complete surprise” and added that his weight and legacy were not something he thought lightly, according to the variety show.
Joining him is Paapa Essiedu as Severus Snape, a complex potion master whose loyalty always attracts fans. This British actor is known for his BAFTA nomination performance in I May Destroy You. Meanwhile, beloved British comedian Nick Frost is identified as the caretaker of the semi-giant Rubeus Hagrid, whose loyalty to Harry Potter remains one of the series’ most likable relationships.
Support actors add depth to the Magic Universe
In addition to the Hogwarts core teachers, the Actors Tournament also introduced Luke Thallon, a recurring role of Quirinus Quirrell, a key role in the series Early Arc.
Paul Whitehouse, known for his long-running comedy work in the UK, will play the role of Argus Filch, the castle’s squid guardian.
The formal announcement ended weeks of speculation, with early rumors suggesting that many compelling names have been considered.
“We are delighted to bring together this extraordinary talent to reimagine a new generation of characters,” Gardiner and Mylod said in a joint statement. “Each of them brings their creativity to the world and we long for viewers to see their explanations.”
A new life of eternal stories
HBO series produced by HBO in collaboration with Brontë Movies and TV, Warner Bros. TV and Dingsheng Movies. JK Rowling is executive producer along with Neil Blair and Ruth Kenley-Letts.
Production is expected to begin later this year, and a wide range of gig calls have been launched for the leading trio of Harry, Ron and Hermione. According to Metro’s report, more than 30,000 children reportedly submitted auditions.
Although the reactions to the reboot remain mixed, some praised the opportunity for more accurate adaptability, others questioned the creative function of the remake – the project continues to attract great global attention.
For now, with the unveiling of Dumbledore, Snape, Magnagar and Hager, Hogwater Gate is once again open for a new era of storytelling.
