Chilean director Alejandro Jodorowsky—the blissed-out force behind such trippy fare as EL TOPO and THE HOLY MOUNTAIN—had a magnificent vision. He would turn Frank Herbert’s sci-fi, spiritual, operatic novel Dune into a picture that would deliver the hallucinatory equivalent of LSD. His cast was to include Mick Jagger, Orson Welles, Salvador Dali, and his son Brontis, who underwent 2 years of rigorous martial arts training for his role. The film was to be 4 hours long. But it was never to be made. JODOROWSKY’S DUNE explores the brilliance and the craziness around this epic-to-be which never was, yet wound up influencing everything from STAR WARS to ALIEN. PG-13. 90 Min.
