I don't think we are going to have to worry about Freeman's portrayal of Bilbo. I think he will pull it off.
Has anyone else been a little surprised at some of the dwarves? When I first saw all the dwarves I couldn't understand why they made a few of them almost human like (I think it's Kili and Thorin).
I mean, you have this rich, established universe of humans, elves, dwarves, etc, and you've gone to great lengths in the LOTR movies to describe dwarves (beards, short, women looking the same as men, etc), and then we now see two dwarves who look pretty much human. I don't get why we see such a big difference in the dwarven "look".
