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 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.

Catherine Keener really gets me. She and I have such a shorthand together.

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 anything, I learned most from being a huge fan of his and watching movies like Annie Hall and Manhattan over and over again - that influenced the kind of movies that I wanted to make more than anything else.

That said, it was pretty awkward and a weird thing to shoot. Some women had a sense of humour about it and we'd laugh, but some were very serious and suspicious... like I might be doing something bad, or maybe they were just uncomfortable.

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.
