The movie is in my head and that's the movie. But I'd be crazy to not be flexible. I think because I have the movie in my head, I can be flexible. I know what's going to work and not work and I know, generally, what I can change and bend and have the movie still work.

What are we taking from people and what do we give is a life-long struggle, I think, for most of us. Who are we? Do we like who we are? Do we know who we are? Do we care? Does anyone care? That's such a big topic. I could tackle that in many movies. So could other people.

If I had cast someone else who didn't have that kind of timing, it would have been leaden and one note. But Ann [Morgan Guilbert] made her really human and really funny without being caricatured or over the top. She feels like a real person.

I know I repeat myself in all my movies, but I just let it go, let it happen. Clearly, I'm not finished with that issue. But they seem to me like completely different movies. They're definitely coming from me.

I hear a lot of, "We want to make a movie with you." Then "No, we don't want to make this one. We want to make that other movie with you." I don't really get that and it's very frustrating. It angers me. Because my movies are my movies.

The casting director on the movie made me aware of her. She told me what to watch Starter For Ten, which I did and thought she was great in. She was just so charming and beautiful. But I felt she could probably look plain if we tried. And when I subsequently met with her, I was so charmed by her vulnerability and sweetness. Those were two qualities that were the most important for that character.

I wrote lots of scripts that never got made and they were terrible. I thought they were good at the time. You can't write two scripts and expect your career to take off. Keep writing. Be you. Be original. A lot of people go for a genre, which is fine if you can do that really well, but we all have such layered histories. We all come from a unique background. Write about your past, write about you. Or make stuff up, but make it about something that really matters.
