For decades, Frank Herbert’s epic science fiction novel Dune (1965) was generally regarded as unfilmable, a literary work that defied transposition into another artistic medium. Never one to balk at a challenge, David Lynch embarked on his own adaptation of Dune in 1984. With neither the majesty of Stanley Kubrick’s 2001: A Space Odyssey (1968) nor the commercial appeal of the Star Wars franchise, Lynch’s version largely faded into obscurity, though it has since become something of a cult film. Before Lynch, experimental Chilean filmmaker Alejandro Jodorowsky had, according to Frank Pavich’s documentary Jodorowsky’s Dune (2013), planned a ten- to fourteen-hour production, starring Salvador Dalí, Orson Welles, and Mick Jagger, among others. That project was, unsurprisingly, abandoned; we are left to ruminate on what might have been.
