Oh, would that Alejandro Jodorowsky could have made his version of the Dune movie. From Dune’s Wikipedia entry:
In 1975, Jodorowsky planned to film the story as a ten hour feature, in collaboration with Orson Welles, Dan O’Bannon, Salvador Dalí, Gloria Swanson, Hervé Villechaize and others (whom he nicknamed his “seven samurais”). The music would be composed by Pink Floyd. Jodorowsky set up a pre-production unit in Paris consisting of Chris Foss, a British artist who designed covers for science fiction periodicals, Jean Giraud (Moebius), a French illustrator who created and also wrote and drew for Metal Hurlant magazine, and H. R. Giger. Moebius began designing creatures and characters for the film, while Foss was brought in to design the film’s space ships and hardware. Giger began designing the Harkonnen Castle based on Moebius’ storyboards, and Dali was cast as the Emperor with a reported salary of $100,000 an hour.
