" For Gone Girl, I knew Nick and Amy had to be very believable, so I made ipod playlists for them, and knew their netflix queues. I wrote scenes of them in childhood from other people’s points of view: A scene of Amy in highschool, written from her friend’s POV, or Nicks kindergarten teacher writing about parent-teacher conference night. Stuff I knew I’d never use, but would help me flesh them out. I do that a lot when I’ve hit a writer’s block — it keeps me writing and sometimes helps solve a problem. Amy’s Cool Girl speech started as a writing exercise, but that one I liked so much I kept it for the book. Once I have a first draft, then the actual real work for me begins, because then I can see the novel as a whole and see what needs work. I do tons of rewriting; it’s where the book becomes a book. "
