Keira Knightley

But acting is very much a profession that is you're hot one moment and not the next - and that is totally cool. I think that's what I find most fascinating and most exciting about it - is that it can be gone in a puff of smoke.

The most moving scene for me in 'Pride and Prejudice' is the Pemberley music room scene: Elizabeth has just saved Darcy's sister from embarrassment and confusion, and as the music plays on, Darcy's look of gratitude becomes a look of love, which we see reciprocated in Elizabeth's eyes.
