Veteran actor Richard Harris — whose best known films include Camelot and The Field — has died at 72. He succumbed to Hodgkin's disease on Friday in a London hospital, where he had been undergoing chemotherapy treatment. Beloved for his wizardly white mane, the Irishman most recently played Hogwarts headmaster Albus Dumbledore in the first two Harry Potter movies. Over the weekend, Potter producer David Heyman told Britain's ITV News that he will reluctantly recast the role of Dumbledore in the upcoming third installment. "We will find a new Dumbledore," he said, "but there will only be one Richard Harris." For more on Harris's death, click here.
