Drawing on the experience I have of now directing, to me, my one strength that I know is my ability to communicate with actors and therefore make characters really important.

My cats I have Luna who's just had kittens recently and we called one of them Dumbledore. They're nice but they're not like their characters.

Sometimes I`m stressed and I`m sick of things and I need to forget about them for a while, so in Harry Potter you`re taken to this wonderful imaginary world where everything is so different. But also the main characters are completely real and modern so you can relate to them.

I don't want to know what they think of me - there's always going to be someone who won't like it and that'll just upset me. So, if I'm happy with it, it just matters if I've done my little vision.

About 200 girls went into a room and there were two casting agents and they asked you to say your name and where you came from and then they picked two or three out of that. And they sent you into a room and I was really nervous and kept dropping things and I was going the wrong way and everything. Then she gave us a script and you had to learn it.

One week I was in school and the next I'm at Leavesden Studios in Dumbledore's office reading scenes with Daniel Radcliffe. Weird. And terrifying for such a huge 'Harry Potter' fan
