Thousands of people turned up to the premiere in New York to see the young actors who star in the third movie.

Daniel Radcliffe, who plays Harry, said: "It's astonishing. It's really, really, really scary but it's brilliant," he raved.

Other celebs there were Emma Watson, Rupert Grint, Tom Felton, Robbie Coltrane and Alan Rickman.

'Great film'

"We have worked on the film for 11 months and it's really gratifying that everyone came out to support it. It's amazing," Dan continued.

A few lucky fans got to see the movie itself after the stars had walked the red carpet.

Al, 11, said: "It might be scary for some little kids, but I thought it was very good. I think the adventures are more interesting."

And 10-year-old Juliet added: "I thought it was really good, way better than the other ones. It seemed more realistic than the others."
