Thanks for sharing that. I'm currently reading the hobbit (again) and I can't wait to see it on film.
Some more info from OneRing.net ... nothing solid in the way of casting though, although they insist that whoever is playing Bilbo already knows who he is. With filming starting early next year, I'd have to agree.
