Production on the new `Harry Potter` revival series began in July 2025, but few official photographs have been posted thus far. The first unofficial photos and videos of actor John Lithgow in costume as Professor Albus Dumbledore, the headmaster of Hogwarts, have emerged from the set. The released footage shows the actor in full costume as the headmaster of the wizarding school, Hogwarts.

On X, multiple fan and update accounts tweeted the leaked photographs of Lithgow standing on a beach scene. His attire consists of a long royal blue robe, blue shirt, dark blue leggings, and boots. He has a lengthy white beard that almost reaches his legs and is wearing slim half-glasses.
