There is always this thing of will you get too old for your part? But people are playing a lot younger than they actually are in real life. I don't think it's as big an issue as a lot of people are making it out to be.

What I learned is that acting is to a large extent about trying to stave off self-doubt long enough to be natural and real onstage.

Because I'm short and slim, I can identify with somebody who's an unlikely fit for something and desperately wants to be part of it.

I'm an atheist, but I'm very relaxed about it. I don't preach my atheism, but I have a huge amount of respect for people like Richard Dawkins who do.

I've always had, like, from the age of about 11, I've had such an intolerance for bad behaviour of actors that I don't think I was ever going to be that person.

I definitely want to go on acting for as long as I can find employment. I'm never happier than when I'm on a film set. I just want to keep working.

I will never, ever do a film as successful as the Harry Potter series. But neither will anyone else.
