Benedict Cumberbatch is limbering up for his role in The Hobbit.
The Sherlock actor has taken on the role of Smaug the dragon in Peter Jackson's forthcoming Lord Of The Rings prequel and starts filming in January.
He told Collider: "I'm physicalising Smaug as a dragon I'm not just doing the voiceover, so it'll be a physical role which I'm no stranger to. I did Frankenstein at the beginning of the year with Danny Boyle at the National Theatre and playing the creature in that was a very full on and sort of corporeal experience."
"I've already started working out and doing various movement exercises to get myself limber for that all-important jump suit with balls on it, otherwise known as motion-capture. But I can't wait, I'm really excited," he added.
Benedict, who has just finished filming the second series of Sherlock with his Hobbit co-star Martin Freeman, is currently filming a Tom Stoppard series called Parade's End for HBO and BBC, and will start discussions on the second Hobbit movie after filming wraps on that.
He said: "I can't wait, but the conversations have yet to start really in earnest because they've been doing the first film... It's a world away but come a month's time we'll start conversations."
