Radagast on Lord of the Rings Wiki
The wizard Radagast the Brown (Sylvester McCoy) is only mentioned in J.R.R. Tolkien’s Hobbit book once, but Boyens had enough to go on to boost his role in the new movie series, and she feels he’s going to become a well-loved character. “He’s not at all like Gandalf,” Boyens says. “There’s a power and danger and sharpness and wits and cunning even about Gandalf that you sense immediately, whereas Radagast is much quieter and gentler. You could mistakenly think he’s not even a wizard or that he might not have any powers of his own, and then you discover that he does.”
I'm not the least bit familiar with the character (I read the book once, a long
time ago), but McCoy looks great. This will be my first time seeing him in anything other than Doctor Who.
