Harry Potter TV Series Reveals First Six Cast, Featuring Hagrid and Snape

by Savannah May 26,2025

Warner Bros. and HBO have officially announced the first six actors set to portray iconic Hogwarts teachers in the eagerly awaited Harry Potter series. This announcement comes after months of speculation and rumors about how the series will reimagine the beloved story of Harry, Hermione, and Ron. The cast list was unveiled today, confirming some previously speculated names and adding new ones to the mix.

Leading the ensemble is John Lithgow, known for his roles in Conclave and Dexter, who had already hinted at his involvement by revealing he would be playing Albus Dumbledore. Joining him are Nick Frost, famous for Shaun of the Dead and Hot Fuzz, as Rubeus Hagrid, and Paapa Essiedu, recognized from I May Destroy You and Black Mirror, as 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.

In a joint statement, showrunner and executive producer Francesca Gardiner and director and executive producer Mark Mylod expressed their excitement: "We’re delighted to have such extraordinary talent onboard, and we can’t wait to see them bring these beloved characters to new life."

The roles of Dumbledore, Hagrid, and Snape are not only central to the Harry Potter universe but also iconic in broader pop culture. John Lithgow, who will portray Dumbledore, shared his thoughts on taking on such a significant role. In a February interview with ScreenRant, he said, "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. 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."

While the new Harry Potter series has yet to announce a release date, production is expected to commence soon. Details on how the series will diverge from the original novels and the films that followed in the 2000s and early 2010s remain scarce. However, Warner Bros. has assured fans that the series will explore Harry's story "a little bit more in depth than you can in just a two-hour film." The involvement of controversial author J.K. Rowling in the show's development has also been confirmed.
