The Guildhall in London was all dressed up to look like the Great Hall at Hogwarts.
Hundreds of reporters from all over the world piled in to hear what the cast and crew of Harry Potter and the Chamber of Secrets had to say.
Read on to get all the goss.
----------------
How much has life changed for you?
Dan: My life has changed surprisingly little. People come up to me and ask me about the films which is cool, and it's great to hear what they think about it all. But I do plenty of normal kids stuff, like hanging out and having pizza parties.
Emma: I like to keep my life as normal as possible with my family and friends. I guess the main things that have changed is that I get recognised and I've got an action figure of myself!
Rupert: I think it's cool being recognised. Although I have tried setting up disguises but the never work!
---------------- How do you feel about the action scenes in the movie?
Dan: Action scenes are so much fun. In one of the car scenes I was actually hanging out of the door for real about 35 feet up in the air which was really cool. I do most of my stunts myself.
Rupert: Stunts are one of my favourite things. Being in the car was like being on a theme park ride.
----------------
What was the most challenging scene for you?
Dan: Speaking Parseltongue was really hard to get the hang of.
Emma: Some of Hermione's lines left me wondering what on earth she was going on about!
Rupert: The spider scene. I don't like spiders in real life - even the rubber ones scare me.
----------------
What was it like working with Kenneth Brannagh?
Dan: It was an honour to work with him, but intimidating when I first met him. He's this amazing Shakespearian actor, but actually turned out to be one of the nicest guys I've ever met.
Emma: He was really down to earth. He got the character of Lockhart just right - really cheesy and funny.
Rupert: I thought he was really funny and really easy to talk to.
----------------
What do you think about Dobby?
Dan: I think he's great, and if he was mine I'd get him to do my homework for me.
Emma: I think he's really sweet.
Rupert: He doesn't seem useful to me at all!
Jason Isaacs [Lucius Malfoy]: I think he'd gone a bit Hollywood by the end of it - he spent most of the time in his trailer!
----------------
Out of Harry and Ron, who would Hermione choose in the film, and who would you choose in real life?
Emma: (Embarrassed) Well I can't say who she'd choose in the film. And as for real life, I'm much better at arranging other people's love lives.
And do the boys have girlfriends?
Dan: I'm really flattered by all the fan letters I get, but I don't have a girlfriend.
Rupert: Me neither!
----------------
If you were a real wizard what would you do?
Dan: I'd turn invisible to get out of trouble and into rock concerts.
Emma: I'd like an owl coz it's cheaper than texting.
Rupert: I'd have the flying car coz it's really cool.
----------------
What's it like going back to school?
Emma: On set we had a tutor for a minimum of three hours and a maximum of five so we kept up with our work. I enjoyed going back to school and being normal again. I've got big exams this year.
Rupert: It was fine. My friends were all really normal with me, but my teachers suck up to me a bit!
Dan: I've just started a new school and it's really great.
----------------
What was your favourite scene?
Dan: The duelling scene with Lockhart and Snape, and I love the scenes with the big crowds in.
Rupert: I liked the slug scene best. They actually tasted really nice coz they were all different flavours - chocolate, peppermint, orange and lemon!
