Freddie Highmore

As always, with acting, you can't be too self-conscious. You shouldn't care about what people are thinking about you at the time because they're not caring about you, they're caring about the character.

People have different expectations when you're younger - it's less about changing yourself into a character; they want a more natural thing. And they just want you to be able to turn up every day and carry on working. They have a horrible fear of 10- or 11-year-olds, that they're going to say 'I don't want to play today.'

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.

Every time I see documentaries or infomercials about little kids with cancer, I just freak out. It affects me on the highest emotional level... Anytime I think about it, it makes me sadder than anything I can think of.
