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.

Ironing boards are a classic example of something I find horrible about modern society: the excitementation, for want of a better word, of mundane things.

If I can make a career for myself after Harry Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.

Well, I think I’m a feminist, just by the virtue of the fact that I believe in equal rights for everyone.

Some actresses are just insane. I've never worked with a nasty actress - they're all absolutely delightful. But completely barking.

You pick projects for the part, the director, and the script. I just want to do different, interesting stuff.

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.
