Trent Reznor on How He Made the 'Gone Girl' Score "Rot Inside"

He and Atticus Ross wrote far more music for the film than they needed to

It's hard not to get chills as soon as the Gone Girl soundtrack kicks in, and that's exactly what the composers were going for.

Trent Reznor, who wrote the hit thriller's score with Atticus Ross, told CBS News that he immersed himself in the film's world as much as possible during his writing process.

"In this case, [I] read the book, read the script, spent a lot of time with [director] David [Fincher] thinking about asking him what he was looking for," Reznor said.

Fincher wanted Reznor to "create sonically something that might appear to be perfect and pleasant on the outside but have it sort of rot inside," the Nine Inch Nails frontman said. 

Instead of just writing music for a specific scene, Reznor and Ross would "think about what might fit in [the film's thematic] space, almost like set design, and run it by David to see how it feels." The process was successful but "ends up being a lot more work for us as composers," Reznor admitted. It's the same way they wrote the scores for Fincher's The Girl With the Dragon Tattoo and The Social Network, with the latter earning them the Oscar. 

Still, Reznor isn't complaining. "It's been just such a rewarding experience for me personally," he added about writing music for Fincher's films.
