You have to find out who you are aside from what the media say you are. If you've become reliant on them for kind of a sense of self, then you're really screwed.

I'm not an easy person to love. There are lots of times when I'm a very good boyfriend, but there are times when I'm useless. I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things.

I absolutely don't relate to being beaten down my whole life - I had amazing opportunities at a young age - but there is still in many, many people's minds the notion that I'll never be able to escape Harry Potter.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

There's a lot of work that needs to be done, and there's a difference between talking the talk and walking the walk.
