When David Fincher first approached Nine Inch Nails’ Trent Reznor and partner Atticus Ross to talk about music for the score of "The Social Network," they had no idea how to compose for the movies. He and Ross decided not to learn how to do it from experts, but to figure out organically how their music could work on film. They won the Oscar for that score, and went on to compose the soundtrack for Fincher’s next, "The Girl with the Dragon Tattoo."
For "Gone Girl," Fincher came in with an idea to build from–ambient sound, spa music. The composers took it and ran. The score starts out superficially bland and sweet–but gets darker and nastier. Watch the video below to find out how the men collaborate.
