Among cineastes, filmmaker Alejandro Jodorowsky's ambitious─and failed─attempt to make a movie based on Frank Herbert's sci-fi novel "Dune" in the early 1970s has long been the stuff of legend. This documentary reveals the story behind one of the "greatest movies never made," with Jodorowsky himself spinning the tale of how he brought together a once-in-a-lifetime group that included David Carradine, Orson Welles, Salvador Dalí, and Pink Floyd. 90 min. Widescreen; Soundtrack: English, French, German, and Spanish Dolby Digital 5.1; Subtitles: English. In English, French, German, and Spanish with English subtitles. Two-disc set.
