In December 1974, a French consortium led by Jean-Paul Gibon purchased the film rights from APJ. Alejandro Jodorowsky was set to direct. In 1975, Jodorowsky planned to film the story as a ten-hour feature, in collaboration with Salvador Dali, Orson Welles, Gloria Swanson, David Carradine, Geraldine Chaplin, Alain Delon, Hervé Villechaize and Mick Jagger. The music would be composed by Magma, Henry Cow and Karlheinz Stockhausen or 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. Jodorowsky's son Brontis Jodorowsky was to play Paul Atreides. Dan O'Bannon was to head the special effects department. wikipedia.org via io9
Dali and Jodorowsky began quarreling over money, and just as the storyboards, designs, and script were finished, the financial backing dried up. Frank Herbert travelled to Europe in 1976 to find that $2 million of the $9.5 million budget had already been spent in pre-production, and that Jodorowsky's script would result in a 14-hour movie ("It was the size of a phonebook", Herbert later recalled). Jodorowsky took creative liberties with the source material, but Herbert said that he and Jodorowsky had an amicable relationship.
The rights for filming were sold once more, this time to Dino de Laurentiis. Although Jodorowsky was embittered by the experience, he stated that the Dune project changed his life. Dan O'Bannon entered a psychiatric hospital after the production failed, and worked on 13 scripts; his 13th became Alien.
