Claims he’s playing Radagast the Brown
The former Doctor Who told fans he has been cast as Radagast the Brown at the Armageddon Expo in Auckland yesterday. Apparently McCoy had meetings in Wellington with Jackson and co-producer and co-writer Philippa Boyens last week, where he was offered the role, but contracts have not yet been signed.
Radagast the Brown is one of the Istari, or Wizards, who were sent by the angelic Valar to aid the Elves and Men of Middle-earth in their struggle against the Dark Lord Sauron. He is mentioned in the book The Hobbit, but doesn’t actually appear, so it seems Peter Jackson may be expanding on the book somewhat, and drawing in elements from the Silmarillion, perhaps.
