Pratchett's one of my heroes. I still haven't found a single statement of his to be wrong, however ludicrous they sometimes sound. It's a bit like Stephen King, great writer but most films are of very questionable quality. Too bad no director like Terry Gilliam or Peter Jackson would take a crack at one of their books. Dare I pose a question to you, Which book of Pratchett would you like to see turned into a movie? (Probably all of them but, you know, pick one )And who should be in it as actors. Which director would be perfect for it in your opinion?
But....Terry Pratchett books have been made into films. Some better (The Hogfather, Wyrd Sisters), some worse (The colour of magic). I'd prefer the Nightwatch series be made into a series of films, with the old cast of Blackadder goes forth in the main roles: Hugh Laurie, Rowan Atkinson, Tony Robinson. But honestly, I'd prefer some of his books be made into animated films, perhaps with Pixar quality. I believe his is not exactly a style that could be suited by actors and a realistic approach. The Discworld is a world far removed from our realities and our rigid rules. Animation would suit it perfectly, perhaps Pixar, or Dreamworks (as they've done some really good work in recent years).
Your right but the movies I've seen so far are, in my view, crediting little to the stories, Which is not shame, since it seems to be an almost impossible task to pich the essence out and distill it in to a feature film.
And again your right, I did mean more the mixed type with probably some live actors and characters in more or less animated environments. I think the trouble with Pratchetts stories is that he makes a potpourri of humour, action and historical, cultural, philosophical and scientifical ingrediŽnts. It's a bit of a rollercoaster on xtc sometimes. I guess I see that back mostly (in my experience cos' I 've not seen every animated maovie ever made)in films like Wall-E. Since I'm from the sixties I 've seen pretty good movies from Gilliam back then in the eigthies like Baron of Munchhausen and timebandits which kind of have the same mix of absurdity and historical influences (Fantasy has to be based on something ultimately)
How about Aardman studios? That would give it an interesting angle, or maybe Tim Burton and Johnny Depp, allthough I think he's most excellent in his role as captain Jack Sparrow.
