Sylvester McCoy spoke to the Argyllshire Standard this weekend and confirmed he was in contention, along with another actor (no idea as to who the other actor may be), for one of the wizards part:
I am being cast in The Hobbit. We're currently in negotiations - there are two of us under consideration. It's not the Bilbo role, but could be bigger.TheOneRing.net goes further by suggesting that McCoy could be playing Radagast the Brown, a character who is part of the Tolkien lore, though he never appeared in director Peter Jackson’s Lord of the Rings trilogy.
They are basing their assumption on the fact that Radagast the Brown will have a bigger role (the fact that he wasn’t in the first trilogy at all WILL definitely make it a bigger role – just saying) in The Hobbit.
Since Sylvester McCoy almost played Bilbo Baggins (the role ultimately went to Ian Holm), it’s sweet to know that in all likelihood we’ll get to see him in The Hobbit either as Radagast or as another character.
What say you? Would you like to see Sylvester McCoy a.k.a. Doctor No. 7 play Radagast the Brown in The Hobbit?
