It wasn't like a Maths test where I have to strain to get it right. I feel very close to Luna so acting her was just natural. And if I had got too nervous I'd have done terribly.

I got very carried away with my 'Harry Potter' life and we did have school but I didn't study. I just had fun.

They warned me, 'you're going to be doing the screen test with Daniel Radcliffe a week after the audition.' And then in the hair and make up department, he walked up behind and scared me. But you get used to him quickly because he tries to make you feel very welcome and at home.

I feel like I've got this anti-marriage thing, but it's less that and more I'm overthinking it to get it right.

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.

It was this feeling the whole time like I shouldn't be here among all these stars and professionals. I was trying to keep my distance because I wanted to watch everyone. But they want you to feel at home and be part of it, and it became normal very quickly.
