The only time I can really relax is up a tree or somewhere outside. I love being outside.

One thing that people keep on saying to me is that the wealth and the fame must have made up for missing out on my childhood. But the idea of money - putting a price on your childhood - is ridiculous. You will never get those years back and you can't put a price on them.

I remember my first scene with Alan Rickman, and I was anxious because he is a slight 'method' actor; as soon as he is in his cloak, he walks and talks like Snape - it is quite terrifying. But I really wanted to talk to him because 'Robin Hood' was one of my favourite films.

I was in three of the Harry Potter films without reading one of those book, quite thankfully.

When we're not trying to kill each other with spells, we just sit in in Daniel's dressing room watching cricket games on television.

It's such a cool group of people that it [being a part of the DC Universe] feels like, for lack of a better analogy, being back on something like [Harry] Potter. We're working with a really tight, talented family.

I'd love to be in Paul McCartney's shoes for a day. I'd love to pick up a guitar and write songs like he does. Or to experience what it might have been like to be a Beatle for a day.
