I'm interested to see what my next door neighbor is up as far as casting goes (just joking about the neighbor part, although Peter Jackson does live down the road from me)
There's been some crazy articles coming out recently on what he's planning. It will be interesting to see how this plays out.
Casting is still underway at the moment and the role Bilbo Baggins is still yet to be taken.
I would love to see a newcomer or an underground actor take the role.
