I'll take my clothes off - whatever the job requires.

I hope to be scaring children for the rest of my life.

Whether it's acting, directing or writing, I want to be involved in the film industry for the rest of my life.

If someone tried to take the hierarchy thing too seriously - for example, being lovely to producers but moaning to runners about the tea - that would not be accepted on 'Harry Potter'; someone would pull you aside and have a word.

I have done a bit of recording and the songs are available on iTunes, and I've got some nice comments. It's something I enjoy doing, but I'm not looking for a singing career any time soon. As long as one person gets enjoyment out of it, I'm happy to make it available.

I'm always buying gadgets, especially at airports.

What twelve year old wouldn't want to play an evil wizard?
