Between Potter films Lynch returns to her normal life in Drogheda and a hint of normality before the process starts all over again.
“I like Ireland and I have loads of friends there, but I think I want to move to London when I’m older because there’s a lot more to do and I do find it more freeing,” she says.
“I think in Ireland a lot of the time I feel boxed in. In Ireland you really have to break out to do acting, but in England -- and in London in particular -- it’s more accepted. Anything can happen there. You can never be bored.
“But Ireland is nice to come back to, too. We live in the country here and you feel so detached from the world, and that’s quite nice.”
The process of filming and the role she plays have taught Lynch some surprising lessons, too.
“I think Luna is very sure of herself and comfortable with who she is, whereas I am more like most people in that I can get preoccupied with what people think of me. I worry about that when really it doesn’t matter because that’s just someone else’s perception, you know? Luna inspires me to not let it affect me as much,” Lynch says.
“The best part of this experience has been meeting the people who were idols. That has been great because they are amazing people and they do achieve so much though working so hard. But they’re so normal as well and they don’t have airs and you see all sides of them.
“I used to be afraid to appear on the film set because I felt I was not ready and what would I do, you know? But I learned that they don’t expect you to be perfect, and that was a great thing to learn. Just to be a part of the film is thrilling, because I’ve always been a huge fan of the books, and now I can say I did my part for it.”
Luna and Dumbledore: Meant for each other?
Asked is there any part of the whole experience she has never told anyone about before, Lynch demurs before confessing.
“Maybe I shouldn’t say this, because it might get me in trouble. But there’s this big thing among people who are fans of the books. It’s a thing they do as fans called ‘shipping,’ which is short for relationship.
“The fans create ideal pair-ups based on the books. There are some really crazy ones. I don’t know if I should say.
“But some people think Luna and Professor Dumbledore would make a great pair in another universe. I mean obviously he’s far too old for her, but their personalities completely match. They’re calm and accepting and quirky and I think they’re both really creative. I’d say they’d be fun together.”
