In anticipation of the deluge of dwarves in the new “The Hobbit” movie, The Lord of the Rings Project has released a handy flowchart to identify each of the main dwarven characters. And yes, you do want to check out the rest of their site.
I’ll definitely be seeing “The Hobbit” this weekend. I’ve heard nothing but great things about it from various Tolkein fetishist friends. I will say that the way some of the dwarves look almost human and how others look so cartoonish was a little off-putting in the trailers. I hope it doesn’t distract in the actual movie.
