HBO and Max's new Harry Potter TV show will be here before you know it, and we finally know who we'll see as our beloved Hogwarts professors. John Lithgow confirmed his role as Dumbledore back in February, and in addition to the Hogwarts headmaster, we finally know who's playing Severus Snape, Minerva McGonagall, and Hagrid. (And I'm still crossing all my fingers Emma Watson could make an appearance).
“We are happy to announce the casting of John Lithgow, Janet McTeer, Paapa Essiedu, Nick Frost, Luke Thallon and Paul Whitehouse,” showrunner and executive producer Francesca Gardiner and Mark Mylod, who's executive producing as well as directing multiple episodes, said in a statement. “We’re delighted to have such extraordinary talent onboard, and we can’t wait to see them bring these beloved characters to new life.” Let's get into the cast members we know so far!
Here's everything we know about the new Harry Potter cast so far.
