All movie fans love to imagine what the failed projects of legend would have been like - David Lynch's Empire Strikes Back, Vincent Ward's Alien 3 and Terry Gilliam's Watchmen. One of the greats is Jodorowsky's Dune. It has a particular appeal as so many of the creatives involved later went on to be serious movers and shakers in the sci-fi world. Notably Giger and Foss went on to work on Alien. It transpires there's a documentary being made about the ill-fated Dune project and below is a trailer. From this (and the reminiscences he penned as part of his introduction to 20th Century Foss), one can see that Jodorowski is an adorably bonkers fellow.
