I'll never approach a part in the same way again. Piaf taught me so much. In terms of my work, I think I'll enjoy it even more than before, because now I know that characters truly exist in their own right. I'll have a way to bring them even more intensely to life.
The first thing, the main thing, about how I work is I need to understand the character.
I love to work this way - I love the time of preparation. If you feed yourself with all the information and you get to understand who the character is then you can really be her.
I'm always 100% committed to a character, a story and a director, and with Michael Mann it was 1,000%. I don't know how to explain this.
