If you were one of the thousands of people who saw 'Hangover II' this weekend, you were treated to a first look at 'The Girl With the Dragon Tattoo' by way of an epic - and very NSFW - red band trailer.

The trailer, which refers to David Fincher's adaptation as "the feel bad movie of Christmas," teases a particularly bloody affair, all set to Trent Reznor and Karen O's cover of Led Zeppelin's 'Immigrant Song.'

Based on the international best-seller by Stieg Larsson, 'The Girl With the Dragon Tattoo' re-teams Fincher with 'Social Network' co-star Rooney Mara, and hits theaters on Dec. 21.

More importantly, I'm excited to hear new music coming from Trent Reznor. It may not be new Nine Inch Nails music but it still has some of their trademark sound. I, for one, will be looking out for the track in the video once they release it to iTunes!

Check out the trailer below.
