based on "Dune" that came out in 1977, it was called Star Wars. :)

What the documentary tells you is in the early 70s the Chilean surrealist filmmaker Alejandro Jodorowsky, the comic artist Moebius, the screenwriter Dan O'Bannon, and the artist H.R. Giger got some money from a French financier to make Dune and came up with a 1000-page book of storyboards that they made copies of and used to pitch the movie to Hollywood studios to get the rest of the cash they would need. Their vision was so weird that nobody wanted to finance it, but every director in Hollywood (especially George Lucas) borrowed their ideas. O'Bannon and Giger ended up collaborating on "Alien" which of course became another franchise. It's a great documentary, really worth seeing.
