There are a couple different kinds of Discworld books in the Pratchett library: the Vimes books, the Early Period books, the set about Rincewind and/or Wizards/Witches, and the set of odd one-offs. This would be a book about Wizards (although thankfully no Rincewind, who I kinda loathe) but mostly it's about the motion picture industry and Hollywood in general. The only central character who really carries over is Gaspode, the small stinky talking dog. The rest of the book (although the Librarian and the cast from Unseen U show up and play a role)is mainly about the pseudo-magic of the movies. I adore Pratchett's Discworld, but this one just didn't do much for me. When the book is about 350 pages long and you don't have a part you love until about page 300... There are liberal doses of Hollywood in-jokes (names, places, scenes, etc.) and the film buff in me enjoyed them but this book wasn't a particularly stellar example of Pratchett being brilliant. It's still Pratchett, which means it's still a good book, but it's not a great Pratchett.
