'Hangover II' audience members were treated to a first look at 'The Girl With the Dragon Tattoo' this weekend 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.

This just makes my year, since I've read all of Stieg Larsson's books.  I've heard mixed things about the European versions of the movies based on his books, but this looks promising! Too bad we have to wait until what is supposed to be the end of the world for it to come out.

Check out the trailer below.
