In many parts, I start from the outside and then it triggers things within. For 'The Piano,' I went, 'I'm going to learn these piano pieces. I'm going to learn this sign language, and I'm going to do them all day every day, five days a week.' It was a totally physical thing.

Every day, I start with a workout; I do vocal lessons, I do piano lessons.

I need to learn every day.

Every day on set, there was something to watch and learn.

Writing is difficult all the time; the thing is to learn something every day.

The unknown makes people uncomfortable. And even living in a city that's as cosmopolitan as New York City is, there's so many things I don't know about other cultures, even though I encounter other cultures - maybe even 18 or 19 of them - when I get on a subway car every day.
