OFFICIAL HOBBIT TRAILER IS UP!!!! Part 1: Unexpected Journey...

I imagine concerning the journey back they'll just do like Lord of the Rings and not cover it extensively; you'll just see some shots of Bilbo and Gandalf coming back to town (at least IIRC Gandalf was with him when he came back) and some narration over it :o
 
I can't wait.  Also if I recall correctly a couple of the Dwarves never even had lines in the book, so it'll be cool to see how they interact in the movies.

This looks amazing to me. I cannot wait for the movie. Watched all the Behind The Scenes stuff that's on the Hobbit Facebook page. LOTR are some of my favorite films. Bring it on.
