Check out new pictures of Benedict Cumbersmaug’s motion capture for The Hobbit! - The Flickr source actually says in a comment to the first picture that it's from one of the The Hobbit: An Unexptected Journey EE Extras. The EE has been released on iTunes already, so I guess it is possible, though why would they include something that's from the second film? We'll find out for sure soon, I guess. :)
