Michael Gambon

Sir Michael Gambon plays Albus Dumbledore in the film adaptions of Harry Potter and the Prisoner of Azkaban and all subsequent film adaptations. Gambon was cast as Dumbledore after Richard Harris' death in 2002. Michael's performance of Dumbledore has been widely criticised as too loud and unsubtle, almost the opposite of how Harris played Albus. Many were confused when they first saw Michael Gambon in Harry Potter and the Prisoner of Azkaban because his appearance as Dumbledore was much different than the characters appearance in the previous two films, and he was much louder and sounded very different to the other actor Richard Harris. Harris played Albus as a gentle, wise, old man while Gambon portrayed him as being more vibrant and youthful. Michael Gambon would go on to cast in all of the Harry Potter movies.
