HBO’s upcoming Harry Potter series is slowly assembling its Hogwarts faculty, and two more key roles are in the process of being finalized. Sources confirm that actress Janet McTeer ( The Old Man , Kaos ) is in negotiations to play Professor Minerva McGonagall,

There’s a new Albus Dumbledore coming to the small screen. John Lithgow has confirmed that he will portray the Hogwarts headmaster in HBO’s upcoming “Harry Potter” series, which will begin filming this summer.

In an interview with Screen Rant, Lithgow said that he has accepted the role of the Hogwarts head wizard in HBO's forthcoming series: “I'll be about 87 years old at the wrap party."

John Lithgow will be picking up a wand and heading to Hogwarts. The Conclave actor, 79, has confirmed that he will be playing Headmaster Albus Dumbledore in the HBO's Harry Potter television series, which will reboot the iconic franchise.

After the controversial casting of John Lithgow as Dumbledore, the Harry Potter TV show has reportedly found actors to play Snape and McGonagall.

The Battle of Hogwarts, which took place in the Harry Potter and the Deathly Hallows Part 2 film, was hugely skimmed through because of the film's limited duration. In terms of importance, this was a very important battle because it was this fight that finally marked the downfall of the main villain, Voldemort.

The Harry Potter HBO series is in negotiations with Janet McTeer to play Minerva McGonagall and Paap Essiedu is near a deal to play Severus Snape.

John Lithgow himself confirmed he is set to play Dumbledore in the upcoming “Harry Potter” series at HBO. In an interview with ScreenRant, Lithgow revealed he is indeed playing the headmaster of the Hogwarts School of Witchcraft and Wizardy in the hotly anticipated TV remake of J.K. Rowling’s books. For him, it represented a career-defining choice.

John Lithgow has played everything from Don Quixote in Man of La Mancha to an extraterrestrial patriarch in 3rd Rock from the Sun. Next he will be the powerful, wise, and compassionate professor Dumbledore in HBO’s Harry Potter TV show. He confirmed the casting in a recent interview, saying it will “define me for the last chapter of my life.”

Now that a Hogwarts Legacy sequel might be on the horizon, there is one essential feature that every platform needs to support.
