It was a match made in trippy heaven: in 1975, cult film director Alejandro Jodorowsky (El Topo, The Holy Mountain) optioned the rights to Frank Herbert’s sci-fi epic Dune. Mick Jagger, Salvador Dali, the graphic artist Moebius, and Pink Floyd signed on to help. A phone-book-thick script was prepared and the 14-hour hallucinatory project that Jodorowsky called “the most important picture in the history of humanity” seemed to be on its way. But it was not to be. Director Frank Pavich’s inspiring tale of ambition and failure uses phenomenal storyboards, concept sketches and interviews with the principals to revisit the film that could have rendered Star Wars superfluous. “I didn’t read Dune, but I had a friend who said it was fantastic,” Jodorowsky says, capturing the spirit of this idiosyncratic pursuit.
