The "Harry Potter" series set to air on HBO continues to take shape — and now, we've just gotten our first look at John Lithgow as Albus Dumbledore, the wise and eccentric headmaster of Hogwarts School of Witchcraft and Wizardry.

On the social media platform X (formerly known as Twitter), Wizarding World Direct posted some sneaky photos taken of Lithgow in full costume, complete with his long white beard and flowing robes. Lithgow follows in the footsteps of the late Richard Harris — who played Dumbledore in the first two "Harry Potter" movies before he passed away in 2002 — and Michael Gambon, who took over the role in Harris' stead. (Gambon himself passed away in 2023.)
