Peter Jackson has just posted the first photo of actors in costume as dwarves Dori, Ori and Nori from 'The Hobbit: An Unexpected Journey' on his Facebook page.

You may not be familiar with the actors playing them (that would be Jed Brophy, Adam Brown and Mark Hadlow), but Tolkien fans know these three quarrelsome dwarf brothers well.

Read on for Jackson's description of the brothers and to see the full image.
