Played by Richard Armitage ''There are elements of Tolkien's description of Thorin that I'm trying to evolve,'' says Armitage. ''I'm trying to make him more human and less cantankerous the entire journey.''

Played by William Kircher A cousin of Bofur and Bombur, Bifur has an orc's ax still stuck in his head from a past battle. ''When I saw that, I thought, 'Brilliant!''' Kircher says.
