Yes, that bunch of people gathered for Jodorowsky's Dune was the elite of the period. It was like it sparked up a revolution in the way sci-fi films were made: it inspired or directly pushed the production of great movies, like Star Wars, Alien, etc. I wish there was a way to see that film as Jodorowsky envisioned it, 12 hours with Dali, Carandine, Mick Jagger, sets by Giger and music by Pink Floyd. It would be the Holy Grail of sci-fi cinema!

I guess you know it already, but I'll give this link for anyone interested in a documentary about this great unfinished project: Jodorowsky's Dune
