"I'm not the kind of actress that goes home with the character. I mean, you're thinking about the work or the next day's scenes, but not staying in character. But as a film goes on, you become more and more fragile, emotionally. And physically too, actually"

Natasha Richardson's quote speaks to the dedication and commitment of a star to their craft. She is saying that she does not take her characters home with her, but rather she is thinking of the work and the next day's scenes. Nevertheless, as the movie advances, she becomes more and more mentally and physically delicate. This speaks to the strength of the work that stars do, and how they can end up being so deeply bought their characters that it can take a toll on them. Richardson's quote is a testament to the devotion and effort that actors take into their craft, and how it can be mentally and physically draining pipes.
