The problem with making any of them a film is that a lot of the books, however good the books are (and they are all fantastic) most wouldn't make good films. I think, although Night Watch does give a lot away, it would be the best one to convert to film

Most of them have been converted into plays, though, fairly successfully.

Right, I know I have read this book and I'm sure it does exist outwith my own mind. But can some one remind me of the book where - now I'm sure it's Carrot - someone goes off somewhere and there is an upside down mountain and dragons involved. I'm totally lost I just cannot remember the book at all!

The upside down mountain is the Wyrmberg in Colour of Magic, which Rincewind visits. Carrot goes off to Uberwald in Fifth Elephant.

Guards Guards definitly! Carrot being so nieve the letters home! I loved that book
