I know I bitched about Peter Jackson's decision to make three movies out of J. R. R. Tolkien's 'The Hobbit', instead of the originally-intended two. I still think he was motivated by nothing but crass commercialism.
I was disappointed in the first Hobbit movie, which I thought dragged interminably. However, the second movie may be an improvement. This teaser footage has just been released. It looks to be pretty true to the book, and the bone-grinding tension is evident even in so short a piece. I recommend watching it in full-screen mode.
I may just have to watch this episode in a theater next month, rather than wait for the DVD . . .
