MTV Movies has a feature on Harry Potter and the Goblet of Fire, with the cast and footage from the film (some of which you may have already seen). Not only do the interviews spotlight Daniel, Rupert and Emma talking about love and hormones at Hogwarts, but also of the new cast including Katie Leung. Additionally, Stanislav Ianevski, Robert Pattinson, Clémence Poésy are featured as they talk about the filming the danger and action sequences in the movie.
The feature is broken up into different segments, but you find them all by clicking "Play" on Goblet of Fire: Hormones & Hogwarts.
