John Lithgow, 79, has confirmed that he will play Albus Dumbledore in the upcoming Harry Potter TV series.

The actor, who is best known for his roles in Interstellar (2014), Footloose (1984), Conclave (2024) and The Crown (2016), revealed that he was "excited" about taking on the role, previously played by Michael Gambon and Richard Harris in the film series.

Lithgow also opened up about this role "defining the last chapter" of his life, with the 10-year long series requiring a huge commitment to the story, admiring that it has been "a hard decision".

It has previously been reported that the US actor was up for the role, however, this is the first time John has addressed the speculation himself.

Speaking to ScreenRant, John said on taking the role of Dumbledore: "Well, it came as a total surprise to me. 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 aded: "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."

When HBO were asked for a comment on the admission, they released the following statement: "We appreciate that such a high-profile series will draw a lot of rumour and speculation. As we make our way through pre-production, we will only confirm details as we finalise deals."
