The film world is mourning the death of Michael Gambon, who rose to fame as headmaster Albus Dumbledore in the "Harry Potter" films. The Irish-British actor died of complications from pneumonia at the age of 82.

His family told the Daily Mail. "We are saddened to hear of the death of Sir Michael Gambon," read a statement from his wife and son. The family ask that their privacy be respected and thank everyone for their support and love.

Gambon began his career in 1963 and appeared in more than 170 films. He became best known for his role as Albus Dumbledore beginning in the third installment of the "Harry Potter" films. He took over the role after the death of his predecessor, Richard Harris, and played it until the final installment of the series.

In addition to his successful film career, Gambon also made a name for himself as a character actor on the British theater stage and received numerous awards. Queen Elizabeth II knighted him in 1992, which is why he is addressed as Sir. With the passing of Michael Gambon, the film industry has lost an outstanding personality who will remain unforgotten.
