It's not just the dwarfs, though.  Right in the middle is the young Bilbo Baggins, played by Martin Freeman.  Surrounding him are, from left to right, Bifur, Dwalin, Bofur, and Oin, played respectively by William Kircher, Graham McTavish, James Nesbitt, and John Callen.

The image below debuted at Yahoo! Movietalk, accompanying an article focusing on Evangeline Lilly and her preparation for her role in the two films.

Lilly, who plays Mirkwood elf Tauriel, said that she has spent, "four times as much time preparing as I do actually shooting."  She went on to explain, "So, on top of my stunt training -- which I need to learn how to be proficient with the bow and arrow, and with daggers, and in fighting orcs that are, you know, ten feet tall -- I also have to learn the language of Elvish, and I have to learn an RP [Received Pronunciation] neutral English accent for when I speak English."

After years of delays, co-writer and director Peter Jackson is back with material that made him a household name with this adaptation of J.R.R. Tolkein's smaller-scale novel.  Populating Middle Earth are Lord of the Rings veterans like Ian McKellen, Elijah Wood, Ian Holm, Cate Blanchett, Andy Serkis, Hugo Weaving, Christopher Lee, and Orlando Bloom.  Joining them are new additions such as Lee Pace, Richard Armitage, Aidan Turner, Brian Blessed, Benedict Cumberbatch, and Stephen Fry.

The Hobbit: An Unexpected Journey arrives on December 14th of this year, followed by The Hobbit: There and Back Again on December 13, 2013.
