Six weeks ago composer and longtime David Fincher collaborator Trent Reznor told Entertainment Weekly‘s Kyle Anderson that working on Gone Girl (20th Century Fox, 10.3) “has been really fun. It’s been an interesting challenge with some different parameters, and it keeps us on our toes. That’s what makes it good. [But] it’s a much darker film than I was expecting. The book is not exactly uplifting or happy, but it’s a nasty film.” Reznor’s quote would have been just a tiny bit better if he’d said “nasty-ass.”
