Jo Rowling: Out of the five books I've published, writing Azkaban was the easiest, and in some ways I think that shows. Although it's the tricky part in some was, as Alfonso will really appreciate, and Steve Kloves, as the script writer, will really appreciate, because they've kind of had to negotiate the same ascent that I had to negotiate. At the same time, I felt I was really given space to do that, so I - so it was an enjoyable process.

Alfonso Cuaron: The moment that I read the book I-I just felt so connected. I-for me, everything was so clear how it should look as a film, and how it should be told as a film.

Steve Kloves: We tried to discover the best way to convey what Jo was expressing in the page, in movie terms. And um, that lead us to some interesting places.

Alfonso Cuaron: You deal with so many abstract concepts, like the time travelling. It is so..such an abstract thing, and it is so difficult, that even trying to explain it right now..

Jo Rowling: Yeah, it's hard.

Alfonso Cuaron: ...is hard.

Jo Rowling: It is hard, 'cause you just go in circles.

Alfonso Cuaron: But then in the book, everything just makes perfect sense. Jo Rowling: I loved watching that part of the film, I loved watching the time turner sequence. There was just enough humor in it, just enough nearness is..Dumbledore's comment when they come back is just perfect.

Interviewer: Kept reading till you got to the pictures. Do either of you have kids yourselves?

Gary: Yes.

David: Gary does. Not myself.

Interviewer: And are they into Harry Potter? Or too young?

Gary: Yeah. Allie's 14, so-

Interviewer: He's right in the age there.

Gary: Yeah. And the other two, Charlie's 4 ½ and Gulliver's 6. So they've been here and they've got, you know…obviously it's an added thing, that they like Harry Potter. But their dad's in Harry Potter, so-

Interviewer: Are they more excited about that than anything else you've done?

Gary: Yeah, I'm a hero at school. I'm big, big noise at their school.

Interviewer: Suddenly you're a really cool dad.

David: Yeah, well that's the best thing about it, I think, is knowing kids and kids getting mental when they know you're in it. Any kid you meet and anyone I know tells the kid you're in it and they get short of breath. (Laughter)

Interviewer: They also get excited about the film. Gary: When I…When I told-Gulliver's 6. He went into his school and he ran up to his mate Omar and he just said, "Guess what." He said, "Guess what." He said, "Guess who's in Harry Potter." And Omar went, "Harry Potter?" (Group laughter)

Interviewer: Well, the part of Dumbledore is kind of a classic role, isn't it? You've compared it, I think, to King Lear, I read.

Michael: Yeah. You feel a bit like King Lear, dressed like that. And he's all-knowing and all-powerful, isn't he? He's a bit nicer than King Lear. Lear's miserable, isn't he?

Robbie: Absolutely.

Michael: Not very happy.

Robbie: Not very good at relationships.

Michael: He doesn't like his children very much. (Laughter)

Interviewer: No, he wasn't good with kids, was he?

Robbie & Michael: No.

Interviewer: Robbie, you are barely over 6 feet tall. In the movie, you're obviously huge.

Robbie: Eight-foot-six.

Interviewer: Eight-foot-six. Without giving away secrets, how do they beef that up?

Robbie: Well, it's mainly done with very clever camera angles. There are one or two other tricks which I can't possibly discuss.

Interviewer: But at any time, have you got tall shoes to take you up to the enormous height?

Robbie: Oh yea, oh yeah, oh yeah.

Interviewer: So, what's the biggest height you actually physically get to?

Robbie: Eight-foot six.

Interviewer: And how does life feel when you're walking around 8'6"? Robbie: Very perilous. 'Cause you've got all this hair like that and you can't really see your feet.

Interviewer: What is the most ridiculous thing a fan has ever said to you?

Dan: Well I've had proposals of marriage. I hand one, which was bizarre. It was terrifying.

Emma: It was "Dan, marry me."

Dan: Yeah. It was the weirdest one. It was this big sign. And the other one was the towel girl.

Emma: Oh, god.

Interviewer: The towel girl?

Dan: The towel girl. She's a legend.

Interviewer: And what did the towel girl do?

Dan: We were filming-I was doing MTV in New York. And it was freezing cold out. It's not like it was a warm summer's day. It was so cold. And I got up there, and they took me over to the window, and there was a girl standing there wearing nothing but a Harry Potter towel, with a sign that said-It doesn't get much better than this!

Interviewer: That's so flattering.

Dan: With a sign that says, "Nothing comes between me and Harry Potter." It was great.

Shrunken Head: I bet it was. (Laughter) Dan: It was! Yeah.

Shrunken Head: Well, how did you get your star parts?

Oliver: Well, we heard there was an open auditions in Leeds and we thought, "Why not go for it," you know.

Interviewer: What about you?

Matthew: Mine was the same. I'm from Leeds. Mine was at the open audition as well. And I remember all the people queuing up the stairs and everyone was there with the Harry Potter books and they put glasses on without lenses in. And I was just there with-I had a little, small CV and then I thought "Okay, I've got no chance of this at all."

Interviewer: What about you?

Devon: My manager was on the-

Interviewer: Oh, "my manager." (Group laughing)

Devon: Well, he was on to the casting directors and all that about it so I went for an audition over in Ireland. Then I was asked to come over here to do a screen test for either Seamus or Neville Longbottom. So I was there like, "I might get a part in it."

Shrunken Head: Great. And how did they actually break this wonderful news to you?

Devon: Well, I didn't know I had the part until the actual read-through. I was told then I was going to read for Seamus, and then they said, "Well, you've read it all really well so we'd like to take you on," and all that. So went on and on from there, again.

Interviewer: Ok, where did you hear?

Matthew: Mine was two or three days after the screen test. Suddenly my mum got a phone call, and I was just carrying on playing and I opened the door and said, "Who is it?" . She says, "It's Lynn from your agency." I said, "Oh, okay." And, well, she gave me the thumbs up. And I just ran in the room started jumping up and down on the sofa. It was really cool.

Interviewer: What about you fellas?

James: Well, we were just sitting in the front room…

Oliver: And the phone rang, so my mum answered it and apparently this lady said, "Hi, is the mum of the Weasley twins there?" I think she said, "No, I think you got the wrong number." (Group laughing) Interviewer: Mum blew it for you. That was it.
