Alejandro Jodorowsky's never-made movie version of Dune is one of the great might-have-beens in science fiction history — featuring designs from some of the greatest artists and an appearance by Salvador Dali. Here's your exclusive first glimpse at the long-awaited documentary about this lost film.

The above clip, shared exclusively with io9, doesn't show off much of the movie's insane designs or reveal much about what Jodorowsky had in mind for his epic space adventure. But it does make some very bold claims about the film, including artist Chris Foss (who worked on it) saying it would have been "bigger than 2001."

We can't wait until we see more of the actual details about this unfinished project, unspooling on our screens. Supposedly the complete documentary includes tons of storyboards and even some brief animated sequences. Can't wait.
