Within the process of filming, unexpected situations occur.

Performance is made in the editing room, and I've come to see the truth in that - the idea that they say performances are usually made in the editing room because what you film is the raw material. I think just going through the process of saying, "Which take do we use? Why is that the take we want? I want that take can you edit again, I'm not sure that's the one, I think it's this one." And just because you go through that process, I think somehow it's made me sort of more open about the [actor's] possibilities.

Being an actor means asking people to look at you. I guess I accept that. But it's a profession in which the job is to show another world and other people. You may access it through bits of yourself, and your imagination and experience, but actually, in the end, you're not playing yourself.
