Lynch Doesn't Deserve The Mocking
OK, OK, he left out a huge amount of story and plot, and then re-interpreted and added to the story to get away with it.
But for picking the right people to play the characters....1st Class.
From the over-the-top excesses of all the Harkonnen characters (The Baron was spot-on) down to the seriousness and Discipline of the young Paul Atredies (one reason I Never got in to the mini-series - A PETULANT Paul Atredies!!) excellently played by Kyle MacClachan. As for Patrick Stewart as Gurney Halleck and Everett MacGill as Stilgar... Who could have asked ask for more?
Unfortunately, I reckon this will be TOO much like the mini-series and not concentrate on the characters enough (Anyone who has read a lot of Frank Herbert, not just Dune, will know that his books are all about the Characters to bring out the story) - It might make a passing semblance at staying true to the original story.... right up until there is the prospect for excessive but non-essential CGI or just to focus on Eye Candy - and you guys who keep saying that the mini-series remained faithful to the books should remember that the Irulan character (amongst many others) is virtually NOT IN the 1st Book at all, and yet there she is constantly appearing in the mini-series, with a whole new role added to the story just to keep the gratuitous glamour shots rolling in.
Get the right people, understanding and playing the right characters and the film will be a winner.
Oh Yeah - And No Condoms over Bent Wire Coat hangers for Sand Worms would be a bonus
