Circus Space Ship from Hell
He hired legendary sci-fi artist Chris Foss for crazy stuff like this.
Jodorowsky wanted the film to look like a psychedelic drug experience. He referred to it as a "messiah."
Jodorowsky hired H.R. Giger (who later created the alien in Alien) to design ONE OF THE PLANETS. Yep, just one of many.

P.S. Mick Jagger agreed to play Feyd Rautha. Salvador Dali was going to play the Emperor.

Ultimately, not a single studio would pay for this movie. Hollywood wasn't ready for the mad scientist behind Holy Mountain to put a crazy story like Dune on the big screen, but you can't help but wonder what would have happened if they had been. If these images are any indicator, Jodorowsky's Dune would have been weird as hell, and totally awesome.
