Thousands of Harry Potter fans were waiting as early as 4am outside the US premiere of Goblet of Fire in New York.
And they weren't disappointed as all the stars of the fourth Potter film took their turn on the red carpet.
Daniel Radcliffe was amazed by the fans, saying: You do a film for 11 months and then all these guys turn out to support it. It's fantastic."
He also said he doesn't get bored of playing Harry because he changes so much between each film.
He added: "it's almost like playing a different character each time you come back to it."
Rupert Grint and Emma Watson were also in New York for the premiere, with Emma talking about how this fourth film is more grown-up.

She said: "I think a lot of people are really nervous about the fact that it's going to be much darker, which it is. But I think they'll be surprised by how funny it is.
"I think that Mike (director Mike Newell) has really managed to bring out the humour more than any other director has been able to before."
And the reason for much of that darkness, Ralph Fiennes who plays he-who-must-not-be-named, was at the premiere as well.
He said he loved his costume for Lord Voldemort, which was based on one of the most famous cinema villains ever, vampire Nosferatu.
