Filming is a funny combination of having a good time and not being able to wait until its over.

Yeah, people seem to really relate to it and feel moved by it. It's been the most positively received of all my movies so far. I don't know why. I like it just as much as I like my others, but people think this one is the best or the most interesting. I'll take it, though. I wouldn't want them to be saying my films are getting worse.

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.

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.

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.

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.
