The official UK Harry Potter and the Goblet of Fire site has been updated with a 3-D video of the Trophy room, some new graphics and a section describing the film, cast and crew. More to come soon.
UPDATE: The Yule Ball section of the official site is now online. You can see new pictures of the attendees, select a video, download screensaves, buddy icons and wallpapers and eventually you will be able to create your own dress robes. Enjoy.
