I only know of David's 1984 version and the 2000 mini-series.
The mini-series, although I have not seen it, looks like a joke.
David's movie, (watching it right now) is a "visual feast" to quote Frank Herbert. But, only maybe a quarter of the story is there and condensed by Lynch.
Condensed by Lynch, hmmmm, sounds like a rock album.
I would love to produce Dune. It would have to be three hours long and I would need 100 million for the proper cast and sets. Hmmmm. Don't see that happening.
Ridley Scott was going to do the film (pre-Lynch) and wanted to go with a two picture project. I could deal that idea, if it was a one year wait like the LOTR movies. Dune needs more than two hours. It really needs about five. You could tell the whole thing in five.
Maybe the 2010 version will be good, but I don't see how. The director is making a movie now, and has another schedule before Dune. A project like Dune would take all of a good director's attention for two years. So I see a CGI heavy and acting limp version coming. Pity. You don't get better material to work with.
The problem is, too few directors or producers are up to achieving Dune as it should be done.
