Hobbit movie progressing

[Tuor in Gondolin]

Curious info on ToRN:

As early as August, McCoy started hinting that he had been been cast in a role that was not Bilbo. However earlier this week it started leaking in earnest (from McCoy himself), that he had been cast as Radagast. Confirming the news yesterday at Armageddon adds one more piece to the casting puzzle and confirms that Radagast the Brown, contemporary of Gandalf and Saruman and lover of nature and animals, will indeed be part of “The Hobbit” movies.

I suppose another PJ "improvement." Seems odd, since Sylvester McCoy could have had
a bigger, better role---even Bilbo.

Btw, I thought he was the third best Doctor (after Jon Pertwee and Tom Baker).
