It's quite stressful knowing that every time you walk out the door, someone is going to be giving you a very good look up and down, judging everything you wear.

When I haven't been working I've tried to travel a lot.

I find the whole concept of being ‘sexy’ embarrassing and confusing.

I have had no control over my life. I have lived in a complete bubble. They found me and picked me for the part. And now I'm desperately trying to find my way through it.

Hermione is so close to who I am as a person that I've never really had to research a role. I'm literally rediscovering what it means to be an actress.

If you want to run for Prime Minister, you can. If you don't, that's wonderful, too. Shave your armpits, don't shave them, wear flats one day, heels the next. These things are so irrelevant and surface to what it is all really about, and I wish people wouldn't get caught up in that. We want to empower women to do exactly what they want, to be true to themselves, to have the opportunities to develop.

If I'm feeling tired, I just say, 'I'm going to paint my nails purple and put some lipstick on!'
