“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” says McCoy.
Since Ian McKellen will likely return as Gandalf, speculation is that McCoy will be playing the character of Radagast the Brown with a bigger than expected role in the two-part film. The character is a wizard with a strong affinity for flora and fauna, and lives on the edge of the forest of Mirkwood through which much of the film's journey takes place.
