Harry Potter TV Series Confirms First Six Cast Members, Including Hagrid and Snape

By GeorgeMay 16,2025

Warner Bros. and HBO have officially unveiled the first six actors who will bring new interpretations to the iconic Hogwarts professors in the much-anticipated Harry Potter series. This announcement comes after months of speculation and fan theories about how the beloved story of Harry, Hermione, and Ron will be reimagined for a new audience.

Leading the cast is John Lithgow, known for his roles in Conclave and Dexter, who will take on the role of Albus Dumbledore. Lithgow had previously hinted at his involvement, expressing the weight of the role. "I just got the phone call up at the Sundance Film Festival for yet another film, and it was not an easy decision because it’s going to define me for the last chapter of my life, I’m afraid," he shared with ScreenRant in February. "But I’m very excited. Some wonderful people are turning their attention back to Harry Potter. That’s why it’s been such a hard decision. I’ll be about 87 years old at the wrap party, but I’ve said yes."

Joining Lithgow are Nick Frost, famous for Shaun of the Dead and Hot Fuzz, who will portray Rubeus Hagrid, and Paapa Essiedu, acclaimed for his work in I May Destroy You and Black Mirror, who will step into the shoes of Severus Snape. Completing the initial lineup are Janet McTeer (Me Before You, The Menu) as Minerva McGonagall, Luke Thallon (The Favourite, Present Laughter) as Quirinus Quirrell, and Paul Whitehouse (The Fast Show, Alice Through the Looking Glass) as Argus Filch.

Showrunner and executive producer Francesca Gardiner, along with director and executive producer Mark Mylod, expressed their excitement about the cast. "We’re delighted to have such extraordinary talent onboard, and we can’t wait to see them bring these beloved characters to new life," they stated.

The characters of Dumbledore, Hagrid, and Snape are not only central to the Harry Potter universe but have also become significant figures in pop culture. Each actor faces the challenge of filling the shoes of these iconic roles.

While the Harry Potter series does not yet have a confirmed release date, filming is expected to commence soon. Details on how the series will diverge from J.K. Rowling's original novels and the film adaptations from the 2000s and early 2010s remain under wraps. However, Warner Bros. has assured fans that the show will explore Harry's story "a little bit more in depth than you can in just a two-hour film." It's also confirmed that J.K. Rowling is involved in the show's development.
