First I would probably place men at the bottom of the food chain. On a grander scale, I would say they're reacting to change. Feminism has got to be part of that.
But even with a character like Cary who is relatively outlandish, at the end of the movie he's in a place where I wouldn't have expected him to be - taking on the responsibility of a woman who is pregnant and who used to be his best friend's wife.
But for me, it feels like a natural extension of what I've been doing: exploring relationships. Here you have two relationships and we can explore how difficult it is for people to be together.
