Sylvester McCoy is the wizard Radagast the Brown in Peter Jackson's prequel to The Lord of The Rings. The Hobbit: An Unexpected Journey, opening this December, is the first installment of a new trilogy.
Forgetful, easily distracted and quite eccentric, Radagast is more comfortable talking to animals than he is to people. A fellow Wizard and friend of Gandalf the Grey, Radagast is one of the guardians of the great forests of Middle-earth. Often found wandering the woodlands near his strange little home called Rhosgobal, a sense of dark foreboding has come upon the little Wizard -- all is not as it should be in the darker reaches of Mirkwood.
