The toughest part of acting is never a single thing. It's more like a whole character. I find film really difficult - trying to make it feel like a consistent character when you're filming everything out of order.

I'm not great at having my picture taken and I don't enjoy that side of it very much but I enjoy being with my friends and it's nice to have a reunion.

I'm more the sort of person who doesn't like hugging strangers because we don't know each other, so we shouldn't.

I probably dreamt about running off to America or something when I was 16 because it just seemed like I was studying algebra and going, 'What am I going to use this for?

It doesn't matter what you feel - ultimately, it's what the audience feels. You can finish a scene and think to yourself, 'Oh, God. I was so deep in that moment,' and find it just didn't play. I don't know if I have very good radar about that or not.

It makes it easier, if you can't do an American accent. I don't know. It's different. I played a character in Never Let Me Go where the script for my character was very sparse, and I enjoyed it. With Never Let Me Go, I had a whole book written from my character's point of view, so I always knew where I was. But, with Ryan [Gosling], it was just easy. He's such a brilliant actor and he is so prepared. He doesn't have to warm himself up to be in a scene. He's just in it. It draws you in, in a way.
