"This is a fan made compilation of all The Hobbit: Unexpected Journey trailers and TV spots, including: Announcement trailer, Announcement trailer (G), Trailer 1, TV Spot 1 - 7, UK 1 minute TV spot, Japanese 1 minute TV Spot. Shots and sequences have been re-ordered into the possible running order of the final film. The audio can be choppy in places as original trailer background music overlaps much of the dialogue."
