MoviesOnline: Could all three of you talk about growing up over the course of these five films?

Emma: It’s kind of a bit of a [...] context when you're doing it on screen. Like I remember, especially with the earlier films, Dan and Rupert had grown like a couple of inches by the end of shooting because it was so long, or by the time the film was released. That was kind of crazy. I remember on the second one I was still losing teeth, so that was interesting. One scene I had kind of like a full set and then I had to cover all of that up.

Dan: Not a full false set of teeth. It was one tooth. It wasn't like the whole mouth.

Emma: No, I was saying I had a full set of teeth and then I'd lose one.

Dan: [teasing her] Oh, right, okay, I thought you said, "I had a false set of teeth." [laughs]

Emma: False?! No! [laughs] Oh my God, no! No, I don’t wear false teeth.

[Loud laughter]

Dan: I don't think you realize when you're growing up. I think it's just one of those things that sort of just happens to you and somebody shows you a photograph of yourself when you were 10 and you recoil in horror.

MoviesOnline: Over the years all three of you have talked about fan encounters, but I’m not sure how many opportunities you’ve had to work with a fan. Evanna Lynch was such a lover of the books and she came out on the open call and then got the part. Did you get sense of her reaction to being on the Hogwarts set and being a part of it?

Emma: It's really funny. I guess like the fifth time around, Dan, Rupert and I were just kind of- - It's quite a surreal experience working at Leavesden Studios. You'll be going along on your- - the studio's so big we have little golf buggies. Anyway, we're going along on our golf buggies and they'll just be like- - I mean , we've had like a giraffe, we've had- - no – what was that?.

Dan: A giraffe? We did? [laughs]

Emma: No, not a giraffe. I’m really crazy. No, no, no. Maybe not giraffes but we've had like goats, we've had bats.

Dan: We have had goats and bats.

Rupert: Armadillos.

Emma: Armadillos, that's why you'll be going past and it's like, "Oh, yeah, yeah." And we're sort of past the stage of really- - I don't know. It doesn't really affect us. Like a giraffe could go by and I wouldn't care.

Dan: That almost happened. We've obviously been so adjusted to it we've not even noticed.

Emma: So anyway, the point is that when you step onto these amazing sets, we kind of take it for granted at this point. And when you see Evanna Lynch's face every time she steps on set, it kind of humbles you again and it makes you realize just how amazing the whole experience is. It stops you from getting- -

Dan: Blasé.

Emma: And taking it for granted. It was really nice to have someone who's so genuinely, genuinely just completely excited and just in ecstasy every time she saw something. It was really nice.

Dan: We did have one moment though where it was very, very hard to present an idea to David Yates if Evanna was standing next to you because if you said something and it was even slightly wrong from the technicality of the book, she would not…

Emma: She would be looking at you like [scowling].

Dan: And you would be in deep trouble. So you'd sort of have to be quite careful. Whenever I talked about the wording of the prophecy and she was there, I'd just be like, "Where's the book?" [laughs] But no, it was fantastic to have Evanna around because she is such a massive fan of the books and the films so it was lovely to have that enthusiasm.

Emma: I remember actually after watching the film, the person I was most nervous about finding out their opinion was Evanna. I’d go up to Evanna just like, "What did you think?" I was really, really scared. But she loved it so I was like, "Okay, as long as she likes it, we're good. We're all good. That's good."

MoviesOnline: Of all the actors who have left their handprints and footprints in cement at Grauman’s Chinese theater, is there one in particular you really admire? Also, do you like Los Angeles? What do you like best about L.A.? Did you enjoy the premiere yesterday?

Emma: Yeah, it's really funny. There's lots of things, like when I came the second time to LA, there were so many things I didn't know about it. Apparently my dad went to like the tar pits yesterday which I was just like that was so weird.

Dan: What's he doing at a tar pit?

Emma: It's this massive tar pit which basically loads of animals basically fell into.

Dan: Oh God, that's horrendous!

[loud laughter]

Emma: Yeah, it's nice that he actually had a day yesterday when he was able to actually see LA which is really cool.

Dan: That's deeply disturbing.

Emma: It's not. It's really cool. It's like history. You can see it.

Dan: I was about to say that LA's very clean.

Emma: Let me finish my answer.

Dan: [laughs] I’m sorry.
