In the first review of the Harry Potter and the Goblet of Fire DVD, which will be released in a few weeks, mentions that this DVD has come a long way from Philosopher's Stone (Sorcerer's Stone). There are highlights & lowlights in the DVD review which include sections on meeting the cast, a day in the life of the Triwizard champions and more.
Lizo from CBBC Newsround was lucky enough to review the DVD:
The DVD extras have come a long way since Philosopher's Stone (Sorcerer's Stone in the USA). Film by film we've seen more of what goes on behind the camera on a Potter movie. And Goblet of Fire goes further than any of the previous movies.
Highlights include the inspired choice of writer/director Richard Curtis to interview Dan, Emma and Rupert; the Meet the Champions section with Clémence, Stan and Robert; and the section dealing with the film's climax - the return of He Who Must Not Be Named.
Lowlights include no JK Rowling - by her own admission, finishing writing this book was one of her most challenging experiences. It would have been wonderful to hear from her about this film version. And there's no director commentary from Mike Newell.
