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.'
