'Girl With The Dragon Tattoo' Music Video From Karen O. Released

The Girl With The Dragon Tattoo won't be out until Dec. 21, but bits and pieces of the film have been seeping out onto the web thanks to trailers and extended trailers (below) and now, a video for "Immigrant Song," the Led Zeppelin cover that Trent Reznor, Atticus Ross and Karen O. created for the film's soundtrack.

It's not revealing much, but some of director David Fincher's footage is in the video--which, we must note, reminds us why we fell for Reznor in the first place--and any Lisbeth Salander completist or music nerd should pop over to Pitchfork and watch it right away.
