Warner Bros. has released The Hobbit: An Unexpected Journey Blu-ray Disc Trailer. The Peter Jackson film will be available in 3D Blu-ray, plain ol’ Blu-ray, DVD and UltraViolet Digital Download on Tuesday, Mar. 19, 2013. To view the 3D disc, you’ll need an HDTV, compatible 3D Blu-ray Disc player and 3D glasses. If you haven’t jumped on the 3D bandwagon, the film stands on its own in 2D, if you’re into the medieval fantasy kind of thing.
