Reznor and Ross again collaborated, to score Fincher's film "Gone Girl". Fincher was inspired by music he heard while at an appointment with a chiropractor and tasked Reznor with creating the musical equivalent of an insincere façade. Reznor explained Fincher's request in an interview: "David was at the chiropractor and heard this music that was inauthentically trying to make him feel OK, and that became a perfect metaphor for this film. [... The challenge was, simply, what is the musical equivalent of the same sort of façade of comfort and a feeling of insincerity that that music represented? primary aim was to instill doubt remind you that things aren't always what they seem to be." Richard Butler of The Psychedelic Furs sang a cover version of the song "She," which was used in the film's teaser trailer. The soundtrack album was released on the Columbia label on September 30, 2014.
