Which Harry Potter did Dumbledore actor died? Michael Gambon, who played Dumbledore in ‘Harry Potter,’ dies at 82. Actor Michael Gambon took over the role of Albus Dumbledore in The Prisoner of Azkaban. Actor Michael Gambon, who was best known for playing Albus Dumbledore in the Harry Potter series of movies, has died. He was 82. LONDON (AP) — Michael Gambon, the Irish-born actor knighted for his storied career on the stage and screen and who went on to gain admiration from a new generation of moviegoers with his portrayal of Hogwarts headmaster Albus Dumbledore in six of the eight “Harry Potter” films, has died. He was 82. The actor died on Wednesday following “a bout of pneumonia,” his publicist, Clair Dobbs, said Thursday. “We are devastated to announce the loss of Sir Michael Gambon. Beloved husband and father, Michael died peacefully in hospital with his wife Anne and son Fergus at his bedside,” his family said in a statement.While the Potter role raised Gambon’s international profile and found him a huge audience, he had long been recognized as one of Britain’s leading actors. His work spanned TV, theater and radio, and he starred in dozens of films from “Gosford Park” and “The King’s Speech” to the animated family movie “Paddington.” He recently appeared in the Judy Garland biopic “Judy,” released in 2019. Gambon was knighted for his contribution to the entertainment industry in 1998. The role of the much loved Professor Dumbledore was initially played by another Irish-born actor, Richard Harris. When Harris died in 2002, after two of the films in the franchise had been made, Gambon took over and played the part from “Harry Potter And The Prisoner of Azkaban” through to “Harry Potter And The Deathly Hallows Part 2.” He once acknowledged not having read any of J. K Rowling’s best-selling books, arguing that it was safer to follow the script rather than be too influenced by the books. That didn’t prevent him from embodying the spirit of the powerful wizard who fought against evil to protect his students. Fiona Shaw, who played Petunia Dursley in the “Harry Potter” series, recalled Gambon telling her how central acting was to his life. “He did once say to me in a car ‘I know I go on a lot about this and that, but actually, in the end, there is only acting’,” Shaw told the BBC on Thursday. “I think he was always pretending that he didn’t take it seriously, but he took it profoundly seriously.” Born in Dublin on Oct. 19, 1940, Gambon was raised in London and originally trained as an engineer, following in the footsteps of his father. He made his theater debut in a production of “Othello” in Dublin. In 1963 he got his first big break with a minor role in “Hamlet,” the National Theatre Company’s opening production, under the directorship of the legendary Laurence Olivier.
