What happened after you were called back. Is it true you had to do a screen test, what was that like?

Yes, I had a screen test a week later. It all happened so fast, because 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. It was mad. Brilliant, but mad.

When do you start filming and how long will it take?

Well, for me it doesn't start until March but some of the actors are already back. The filming goes from February til October but I won't be constantly filming the whole time. Some months are heavy, others not so much. Filming is completely off for June because some of the actors have exams.

What appeals to you about the character Luna?

It's like how I was saying before about the books making you forget everything around you and taking you somewhere else.

Luna does that. Sometimes, the other characters are too normal and then you start to be brought back to reality but then Luna shows up and she is just so funny and cool and honest and slightly mad and she's all that matters. She is 100% true. She puts on no shows, because she is so comfortable with herself.

She's not rebelling and being all consciously 'I'm proud of me'- she's just being how she's meant to be. It doesn't occur to her that she's different, because she's not.

Most people have their masks that they wear for other people so that they'll fit in and be 'cool' but she doesn't and that is what 'cool' is. She is also completely independent.

She has no friends and while she would like them, she doesn't brood on it because she can support herself. Most people would be unhappy without their friends.

They need them for support and feel insecure without them but because Luna is so comfortable with herself, this doesn't bother her. She is the perfect role model.
