I think having a good life prompts it... anybody who has a good life and looks around them sees the enormous disparity that exists in the world between those people who do and those that don't. I can't say we walk about our guilt a lot, though. If we do, it probably comes out in the form of self-loathing jokes. But it's a tough thing to wrap your head around... the have's and have not's in the world.

You can't take your stuff with you when you die. That doesn't mean you shouldn't enjoy it while you're alive. Why not? But it's all pretty silly. I fall victim to it. I mean, I want nice stuff too. So I guess I'm poking fun at myself as well as other materialistic people.

I have a boundary problem... I need to know when to give and when to back up. I'll help someone across the street and then into their homes and they'll start telling me all their problems... and it turns out they're insane and want to kill me. I've got to know when to stop!

What's the trick to writing a great female character? Make her human.

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.

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.

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.
