Since their 1997 introduction, the Harry Potter books have sold hundreds of millions of copies. To this day, nearly 30 years later, it remains a cherished and iconic series, despite the controversy surrounding its star author. Between 2001 and 2011, Warner Bros. produced the highly successful Harry Potter movie series. These eight films brought Rowling’s imaginative tales and memorable characters to life. And one of the story’s most famous players is the headmaster of Hogwarts, Albus Dumbledore, played first by Richard Harris and then later by Michael Gambon.
