Trent Reznor made ‘rotting’ soundtrack

Trent Reznor made music that  »rot inside » for ‘Gone Girl’.

The Nine Inch Nails frontman wrote the soundtrack for the thriller with Atticus Ross and admits they spent a lot of time with director David Fincher to create the perfect pieces for the movie.

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

 »[He wanted us to] create sonically something that might appear to be perfect and pleasant on the outside but have it sort of rot inside. »

Instead of writing music for a specific scene, the composers 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 – which the pair also used to write the scores for the director’s movies ‘The Girl With the Dragon Tattoo’ and ‘The Social Network’ – was time-consuming but incredibly rewarding for the songwriters.

Trent told CBS News:  »It ends up being a lot more work for us as composers.

 »[But] it’s been just such a rewarding experience for me personally. »
