John Lithgow Cast as Dumbledore in New ‘Harry Potter’ Series Amid Backlash

BEVERLY HILLS, California — John Lithgow expressed his excitement about taking on the iconic role of Albus Dumbledore in HBO‘s upcoming adaptation of the ‘Harry Potter‘ series during an appearance on BBC’s ‘The One Show’ on Wednesday.

The six-time Emmy Award winner will portray the headmaster of Hogwarts School of Witchcraft and Wizardry, marking a significant departure from the original films, as Lithgow will be the first American actor to step into the role. Lithgow reassured fans that he is ready to embrace the challenge despite some skepticism about his nationality.

“I’m very excited. Very intimidated,” the 79-year-old actor said. Dumbledore was previously portrayed by the late Richard Harris and Michael Gambon in the film series. Lithgow acknowledged the challenges of following in their footsteps but emphasized his commitment to the character.

“I remind everyone that I did play Winston Churchill on ‘The Crown’ and did just fine,” he said, referencing his acclaimed role that earned him an Emmy Award. “But yes, I mean, it’s an enormous thrill. I know there were plenty of people appalled that an American should be hired to play the ultimate English wizard. But I will do my best,” Lithgow added.

The new ‘Harry Potter’ series, which will see Warner Bros. Discovery give the beloved book series a fresh interpretation, has sparked mixed reactions from fans of the original films. Though the show’s new adaptation has been described as “faithful,” some fans are concerned about the timing so soon after the original films concluded in 2011.

In a broader casting announcement, the series confirmed that British actress Janet McTeer will play Professor Minerva McGonagall, London-born actor Paapa Essiedu as Severus Snape, and English actor Nick Frost as Rubeus Hagrid. HBO stated, “We’re delighted to have such extraordinary talent onboard, and we can’t wait to see them bring these beloved characters to new life.”

HBO’s project is expected to premiere in 2026, bringing a decade-long commitment to the franchise as Lithgow humorously noted he would be about 87 years old at the show’s wrap party. “Choosing to accept this role was not an easy decision because it’s going to define me for the last chapter of my life,” he said.

Francesca Gardiner, the series showrunner and executive producer, expressed her enthusiasm in a joint statement with director Mark Mylod, stating, “We can’t wait to see them bring these beloved characters to new life and lead a new generation of fandom.”
