Michael Gambon as Dumbledore in Harry Potter

Richard Harris played Professor Dumbledore in the first two Harry Potter films, though the role had to be recast after he passed away in 2002.

So, Michael Gambon stepped in and took on the role from Harry Potter and the Prisoner of Azkaban onward.

Producers praised Gambon’s warmth and liveliness, affirming he continued Dumbledore’s wise leadership while respecting Harris’s legacy.
