Scottish actor Sylvester McCoy ("Doctor Who") revealed to the Argyllshire Standard that he is in talks to join THE HOBBIT: Mr McCoy told the Standard that contrary to widespread internet rumours, he's not vying for the role of Bilbo in THE HOBBIT (due to start filming next year) - but is one of two actors being considered for one of the wizard parts.
"I am being cast in The Hobbit," he said. "We're currently in negotiations - there are two of us under consideration. It's not the Bilbo role, but could be bigger."
TheOneRing.net speculates that he may be playing Radagast the Brown.
