Well, if she met Lady Gaga, what would she say to her? Would she say, “I was here first”?
She wouldn’t… nothing shocks her, you know. Some people are like, “what are you wearing?” Luna would admire it. She’d be interested. She’d like diversity in everything. To be honest, I wouldn’t wear her things. Her clothes are fun to wear but I would feel too much looked at. But Luna is not doing it to make a fashion statement. She thinks radishes look nice on earrings so she’ll wear them. So I wonder what Lady Gaga would think of her. To be honest, I like Lady Gaga, but I think it’s more of an act. She does it for show business. Luna wouldn’t. That’s just herself.

Have you ever met anyone who copies her clothes?
No. Luna’s colour scheme is like purple and turquoise and I think it’s just something you have to be really confident wearing, really. Luna’s not over confident; she’s just secure. I think most people my age, they’re either doing it to make a statement, like, “I’m going to be looked at”, or else they don’t care. I would like to be like that but to be honest, I’m a bit shy… I don’t like to be stared at, so much.

Luna, Neville and Ginny are leading the resistance at Hogwarts. Can you tell us a bit about that? Did you enjoy that character journey?
Yeah, that was really fun. I love how they sort of take over… when Harry comes back, and he and Ron comes into the Room of Requirement, and they’re like, “Oh, look at what they did!” It’s sort of like, um, I can’t remember … boys in a tree house and they have all these sleeping bags and these little statues in it… it’s really exciting. Harry’s the one who’s always taken the initiative.

Harry, Ron and Hermione, they’re like… “we have to fight”… but now they’re gone and Luna, Neville and Ginny, they do take over. They realize, they can do something, and what they do is very valuable. All their contribution… so that was nice. It’s not like in the fifth book, where we’re just introducing her. Oh, look that’s Luna, she’s kooky, she’s fun. Luna’s just not in the background. She’s there, she’s helping and she’s fighting.

The scale of these films are much bigger than before. How was it different from you this time?
There was a whole different feel to them. Like they’re the end ones so nobody is going to be spared. We were all aware it was the end – there was a good spirit, we wanted to make it better and everything. It’s very hard to encompass that feeling.

If you could change the ending, would you?
No. Everyone’s happy and… (laughs) I know people complain about the epilogue, but I really liked it. A lot of people say it’s too nice, too cheesy, but the whole story is one big bloodbath, you know, there’s stress the whole time. There’s not one bit where Harry’s just like relaxed, and he’s watching TV, he’s not just playing on the Playstation, like most people have those moments. He’s always worrying and he’s always, like, “What does the prophecy mean? How can I do this? Horcruxes…everything!” I really like the end, that it ends nice, and he has children. I’d like to know more about Luna.

Some have even thought she might end up with Harry…
I got a question back in there (she points to previous interview room): would you like it to be more raunchy? I was like, “oh, you’re mixing series here!” No, I don’t think Luna and Harry would at all. I just think she thinks differently to everyone. She’s really open minded. I think Harry would… I imagine him and Ginny.

While they’re great together, I imagine they have a really stormy sort of thing… argue a lot… throw things and shout. I think Luna wouldn’t be so much the romance and passion. She’d be more about exploring things, like she’d get really excited about a creature, and she’d want to share that with someone, so it’d be more a friendship. And I think Harry’s more about the passion.
