I still have issues around forgetting that it's my life and if I want to do something, I can do it.

And the people I'm best friends with on the films are not generally the actors.

I basically have the diet of a 19th-century Irish navy, apart from the litre of stout a day. It's meat and potatoes and bread and cheese: those are my four food groups.

I don't really care about how I look.

Potter for me is something that's been giving me these amazing opportunities to start a career and learn while I'm doing, which is the best way to learn.

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'd love to play Puck in 'A Midsummer Night's Dream.'
