Every movie changes you. The process of making a film changes you. You have to be obsessed, you have to get up at 3 in the morning and go "Wait, I have an idea!" You have to continually be drawn over and over again to deepening inside that story, and ruminating over questions: "Why would he say this to her? Why if he was standing there, would she go?" Every one of those answers has to come from some personal place, and in order to do that, you can't sit on the surface. It's such a big change that you can't really explain it to anyone else.

Interestingly, when you do films, sometimes you have conscious reasons, things that you were looking for, or stuff that you were trying to do. And then, you see the film and you think, "Wow, it ended up being something totally different!"

As an actor, I'm attracted to drama; as a director, it's humor - because it's the story of my life, and I can't be that serious about it. Being alone is a big theme in all my movies, both as a director and as an actress.

Now apparently I'm told that every celebrity is expected to honour the details of their private life with a press conference, a fragrance and a prime-time reality show.

When I went home, my family became a little lonely family because it was just me and my mom. Part of my longing to go back to work was wanting to be surrounded by these people who were teaching me things and drinking bad coffee at three in the morning while we were lying around in a bikini in the winter. Somehow it just felt like real life. It felt more like real life than my life.

With 'Taxi Driver,' I had this eureka moment. I realized that acting could be much more than what I had been doing. I had to build a character that wasn't me.

Just to set the record straight, a salary for a given on-screen performance does not include the right to invade anyone’s privacy, to destroy someone’s sense of self.
