I'm really interested in the minutiae of different tones and what that explains - how people's backgrounds are reflected in minute details of how they interact. It's true that I'm hypersensitive to all that. Writing is acting in the sense that you're imagining and inhabiting another. In the book I was trying to get at the root of what true acting is.

I would have started writing a lot earlier if I hadn't been [Arthur Miller's daughter].

There is a magic thing called 'tone' in a film, that the director must master and maintain.

I think it's very important to keep being frightened - if you're not frightening yourself, you should take a break. You need to keep experimenting. You also need to take time - that's how you do good stuff - layering and depth of knowledge.

You work with each individual actor as you perceive their needs to be. It's something that you've figured out in the weeks of pre-production.

I had a lot of great lakes of ignorance that I was up against, I would write what I knew in almost like islands that were rising up out of the oceans. Then I would take time off and read, sometimes for months, then I would write more of what I knew, and saw what I could see, as much as the story as I could see. And then at a certain point I had to write out what I thought was the plot because it was so hard to keep it all together in my head. And then I started to write in a more linear way.

I never had any desire to become a well-known actress.
