I might have gone to see "Dune", but I really don't like Sting, and his shrill "I will kill him!" was in every preview for that movie that I saw. Never read the book(s).
Arthur C. Clarke was a self-aggrandizing blowhard, IMO.
I have seen Dune I don't know how many times...it was interesting. I also like the version made for the Sci-Fi channel with William Hurt as Leto...It's actually a bit truer and less a surreal adaptation, but I don't think the actress playing Jessica is pretty enough.
