I think it's a very female trait to want to please men and to want to be considered the Cool Girl. And if you take that to the farthest reach, where you're actually selling yourself out and degrading yourself by doing things you don't actually want to do, only in order for this man to think that you do, that's a very perverse thing.
I find, the older I get, the more surprised I am about how hesitant people are to say what they really want, what they really dream about, what really drives them. It's as if sometimes we're sort of embarrassed, as we get older, to be transparent about that. But you save so much time if you're transparent about what you want.
I like the idea that people who see 'Gone Girl' are possibly going to come out with incredibly different reactions to it - not just between men and women, but if you are in a good relationship or a bad relationship. Everyone is going to bring their own bundle of prejudices and viewpoints and experiences to it.
