Lynch: "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."

Lynch: "People like her because she's like a breath of fresh air. Because in the fifth book it gets so dark and Harry's always cross and then every time Luna comes in all the tension goes and she makes you laugh because she's so funny and really honest. I don't know how much I'm like her, there are some similarities but I'm more determined than her."

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

Lynch: "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."

Lynch: "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."

Lynch: "It calmed me down to see that most of the time no-one gets the scene on the first take."

Lynch: "Well just meeting J.K. Rowling was amazing because she created all this world. And all the fans, we all get so obsessed with it and then you met the one person who made it all up. It was just so amazing. And I was just so amazed that that she wrote this book and all of the films have happened."

Lynch: "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."

Lynch: "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."

Lynch: "While I was in London it was completely upside-down. I got a whole new life and it was a challenge to keep in touch with my life in Ireland, but it was great fun. Now though, I've been back home since November and gradually all connections with my HP life have been fading."
