On January 7, 2011, Reznor announced that he would again be working with Fincher, this time to provide the score for the American adaptation of "The Girl with the Dragon Tattoo". A cover of "Immigrant Song" by Led Zeppelin, produced by Reznor and Ross, with Karen O (of the Yeah Yeah Yeahs) as the featured singer, accompanied a trailer for the film. Reznor and Ross' second collaboration with Fincher was scored as the film was shot, based on the concept, "What if we give you music the minute you start to edit stuff together?" Reznor explained in 2014 that the composition process was "a lot more work," and that he "would be hesitant to go as far in that direction in the future."
