AceShowbiz - %cMichael Gambon% has announced that he's retiring from theater acting due to memory loss. Michael, who is best known for his role as Professor Albus Dumbledore in "Harry Potter" film series, told The Sunday Times, "It's a horrible thing to admit, but I can't do it. It breaks my heart. It's when the script's in front of me and it takes forever to learn. It's frightening."
Michael said he realized he could no longer perform in front of a live audience about six months ago when he needed someone to feed him his lines using an ear piece. "There was a girl in the wings and I had to plug in my ear so she could read me the lines," he shared, "After about an hour I thought, 'This can't work. You can't be in theater, free on the stage, shouting and screaming and running around with someone reading to you.' "
The "Harry Potter and the Order of the Phoenix" actor was worried his forgetfulness was a sign of Alzheimer's disease but his doctors said it wasn't Alzheimer's but a result of aging.
Michael's retirement was a huge loss for him. "Theater's the only place for me to be," he said, "When the curtain goes up, on you come. No one's stopping you. No one can shout 'cut.' There's a thousand people sitting there and they can see you moving, all over. They watch every part - how you walk, how you stand. The way you sit. The way you look at people."
Although he may never grace the stage again, Michael will not give up acting altogether. "You've got to go to work, haven't you?" he told the newspaper. He will next be seen on BBC's adaptation of J.K. Rowling's "The Casual Vacancy" and a movie-remake of "Dad's Army".
