As promised, Warner Bros. has released the first trailer for The Hobbit: The Desolation of Smaug, the second installment of director Peter Jackson's pre-Lord of the Rings trilogy. Martin Freeman is back as Bilbo Baggins, having escaped with the rest of his party from the treacherous Misty Mountains. We also get a few additions to the cast, with Evangeline Lilly portraying the elf Tauriel, and Benedict Cumberbatch voicing the dragon Smaug. Take a look at the first footage from this highly-anticipated Middle Earth adventure, debuting in 2D and 3D theaters nationwide on December 13. We also have the international trailer, which is slightly different from the stateside version.
