Re: THE HOBBIT (2012/2013): News, Rumors, Pics Till Release
Sylvester McCoy isn't playing one of the dwarves, rather he's playing Radagast the Brown, a wizard that's part of The White Council.
Also, the added material that expands the story into two films are from The Return of the King
appendices and covers what Gandalf was doing during his absences from The Hobbit
narrative, i.e. investigating the Neucromancer at Dol Gundar (hence Galadriel's and Saruman's return and Radagast's appearance).
