'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.

Check out the trailer below.
