The documentary Jodorowsky’s Dune chronicles the cult filmmaker Alejandro Jodorowsky’s mid-70’s attempt to mount an adaptation of Frank Herbert’s classic SF novel Dune. Jodorowsky is a magnetic raconteur, detailing plans (A score by Pink Floyd! Designs by Moebius! Casting Salvador Dali and Mick Jagger in roles!) that suggest a fascinating divergence from the eventual 1984 David Lynch film.
