Jodorowsky's Dune (2013)

This documentary tells the story of director Alejandro Jodorowsky's unfinished masterpiece: his attempt to produce a film adaptation of Frank Herbert's sprawling science-fiction novel 'Dune' in the mid-1970s -- a project which was never completed, in part because it collapsed under the weight of the director's incredibly ambitious vision for the movie. It was to have been a larger-than-life epic, as grand as Stanley Kubrick's '2001.'

All that survives of Jodorowsky's 'Dune' are the script, storyboards, and concept artwork. Using these, combined with talking-heads interviews of those involved, the documentary tries to show us how the finished film would have looked.

What makes all this so captivating are the interviews with Jodorowsky himself, and his incredible passion as he recounts the tale of an unfinished project from 40 years ago. Entering into Jodorowsky's world is like falling into a visionary dream where anything and everything is possible. And as his vision progresses, it becomes more and more ambitious: Salvador Dalì, Mick Jagger, and Orson Welles agree to star. Dan O'Bannon and H.R. Giger will design the sets and costumes. Pink Floyd will provide the score. It's hard to imagine a more ambitious movie, considering the technical limitations of the time.

Yet, as the documentary shows, the ripples from this never-completed, ahead-of-its-time film spread out in many directions, inspiring different ideas that made their way into later films such as 'Star Wars' and 'Alien' -- and which continue to inspire filmmakers today.
