In spite of the pounding rain, screaming fans packed into every inch of Leicester Square for Harry Potter and the Goblet of Fire, the fourth film in the hugely successful series. Some of them had been camped out since 9pm the night before just to catch a glimpse of the film's stars. But, while they were waiting, a fire-breathing dragon (in a cage for safety, of course) kept them entertained.

For the first time on 6 Degrees Film, you can see live video footage of our interviews with the cast from the film and the other celebrities who strolled up the somewhat soaked red carpet " Madonna, Guy Ritchie, Freddie Highmore, Kate Beckinsale, and Rob Lowe.

Daniel Radcliffe, now age 16, was absolutely bubbling over with enthusiasm. Extremely friendly and polite, he was as nice and instantly likeable in person as his character Harry Potter is in the films. "Oh my gosh. How are you?" he asks after pausing for a quick sip of water. Why is he so energetic tonight? "It's partly nerves and partly that I'm ecstatically happy. Cause when you go to a film like this it's sort of a joy to promote because everyone's so proud of the film. We're all really happy with the way it all turned out."

My most important question for Daniel is that in a lot of ways he's like Harry Potter, growing up in the public eye and unable to have a normal childhood. How does he feel about that? Like Harry, does he wish his own childhood was more normal? "But I do have a normal childhood," Daniel insists. "The thing is, it's very hard to define what a normal childhood is. With me, all I know is on the set everyone is, or most people, are all past puberty " all the crew. So, you know, they're all relatively stable. So to be around very stable people when you're going through a sort of weird, shaky teenage years thing, is possibly the best background you can actually have. So I mean I've had a great time." And, continuing his friendly and polite manner, he actually thanked us for our time before heading off for photos with Emma and Rupert.

It must be difficult for Rupert Grint, now age 17, who tends to get overshadowed by Daniel just as his character Ron Weasley gets overshadowed by Harry Potter. "They've all grown up, and Ron's a bit more of a moody teenager [in this film]. And I think he gets a bit jealous of Harry as well, since he's sort of always the hero." Still, Rupert has thousands of screaming fans of his own yelling for him. "It's quite scary, these premieres, quite hard to get your head around. It's a bit strange, but good fun as well. And this is probably the best film [in the series] as well so far." I suppose most people want to know about the developing relationship between Ron and Hermione as the series continues, so I asked Rupert if he's looking forward to it. In response, he gets an adorable, sheepish smile on his face. "Well, yeah, that's always been�A lot of people have sort of said that. And there's always been that. But we'll just have to wait and see, I guess."

How does Emma Watson, age 15, who plays Hermione Granger, feel about their burgeoning relationship? "It's great. I really hope they get together in the end." At least the two of them agree on that, although they do have different feelings about continuing to play these roles for several more years. "I can promise you I'm doing the fifth one," says Emma, "but each film is so huge and takes such a huge amount of time that I can't make any promises because I don't know how I'm going to feel in two years time." By contrast, Rupert told me "I definitely want to continue doing it, forever really. It's a wicked job. Really good fun."

I asked several of the cast members how they thought the series was progressing as the characters get older and start dealing with more difficult issues " including the always thorny problem of dating and relationships, which begins for them in this film with the dilemma of who to take to the Yule Ball (and thus the beginning of complications for Ron and Hermione). But even aside from dating, this film is far less of a children's movie than the others, with a 12A rating here in the UK (equivalent of a PG-13 in the US). It's scarier, darker, and parents of young children unfamiliar with the novel should be forewarned that a major character does die at the end of the film. What does the cast think about all of this? "Ooh, wow, gosh," laughs Emma, surprised by the question. "They're just getting older and dealing with things that any teenager has to deal with even though they're living in a magical world." Bonnie Wright, age 14, who plays Ginny Weasley, says "I think it's becoming a lot scarier, but I think it's still good even for smaller children."

And what about Robert Pattinson, "Cedric Diggory," the other champion from Hogwarts to compete in the Triwizard games? Does he think the film's still appropriate for young children with what happens to Cedric and the darker sides to it? "Yeah, I think if they've read the book, it follows the book very closely. And I think your imagination is much more terrifying than a film could ever be."

How do the newcomers feel about joining the Harry Potter franchise? Is it intimidating? "Yeah," laughs Robert, "It is now (referring to the hoards of fans outside the cinema). It wasn't until today. But I'm only doing one, so it's not too intimidating." For Stanislav Ianevski, "Viktor Krum," this is his first feature film (as it is for Robert Pattinson as well, although he did have a small uncredited role in Vanity Fair). He gets to escort Hermione to the Yule Ball. "Emma is an extremely lovely girl, and she's a very good friend of mine as well, so I enjoyed it, definitely, filming it with her. It was really incredible." How did he like playing Viktor Krum? "He's funny and horrible at the same time, and he has love, romance, and has to fight, so he has everything. I've really been honoured with this part."

Tom Felton, the actor behind Harry's nemesis, Draco Malfoy, is, I have to admit, incredibly sweet in person, and very easy to talk to. But I had to ask him how he likes being Harry's enemy. "It's a lot better than being his friend! Definitely. It's something a bit different, so I enjoy playing someone a bit more interesting." Why does he say it's better to be Harry's nemesis rather than his friend? "Because being his friend you've got to be all ass-kissy because Harry's the main character. I'm the only one who gets to stick it to him. So I quite like it."

Tom also had interesting things to say about how little kids react to the films: "The younger ones take it to heart. I've had a few letters saying 'Leave Harry alone.' They do take it quite seriously, which is slightly daunting at times, but the older ones, well, apparently girls love a bad boy, so I've been told. I haven't seen any evidence of this yet. Although I can hear them," he laughs as a group of girls outside shrilly scream.

While Hermione attends the ball with Viktor, Ron ends up going with Padma Patil, played by Afshan Azad. Was there a lot of pressure being Ron's date? "No, no pressure, because I don't think Ron was interested in me " as you might have seen in the film. He kind of just ditches me in a corner and says, 'No, I'm not going to dance with you.' Which is quite gutting, but, I pull myself back up and went out there." How does she feel the series is changing as they're getting older and developing relationships and things?

"I think a lot of people will relate to Harry, Ron, and Hermione in this film." As for Katie Leung, who plays Cho Chang, Harry's new love interest, this is her first film as well. "This is so surreal, there's just so many fans outside! I just can't believe I'm here�.I realized there was a big fan base, but not as big as this. Words can't describe it, it's just been amazing." Afshan agreed when I asked her how she liked joining the Harry Potter films. "I'm really enjoying it. It's an overwhelming experience, and I'm enjoying every minute of it, because it only happens once!" How about the premiere itself? "I want to do it over and over again, it's so overwhelming, so flattering. You have people calling out your name, and you think, 'How do you know my name?' You know? It's just really flattering. This is just like a dream come true."

Does Freddie Highmore have the same dream? So far be's had huge success as, most recently, Charlie in Charlie and the Chocolate Factory, but I had to ask him if he's ever wished to act in the Harry Potter films? "Well, you know, they're a lot older than me, but they seem like great fun. I've seen the other ones and they're great."

Yes, they definitely are, and I have to say I agree with the cast that The Goblet of Fire is by far the best in the series, at least so far. The numerous celebrities in attendance and throngs of fans in Leicester Square definitely won't be disappointed with the newest addition of Harry Potter.
