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.

I feel very English in a suit. There's something about being in a suit abroad, particularly in America, that feels empowering.

The sixth Harry Potter film - I don't like my performance in that film at all.

I get constantly mistaken for Elijah Wood.

I would consider doing any part as long as the script is good and the film has an interesting director.

I had to smile when stories emerged questioning whether I was gay. Obviously I knew I wasn't but people were curiously desperate to suggest I was ... when you know a gay guy has a crush on you, it's the most flattering thing.

If you're having a bad day, get on with your job, because you having a bad day can affect everyone around you.
