Jodorowsky's Dune Uncovered
Scenes 1-9 : The Dog-beings.From the Jodorowsky's Dune documentary we know that the film would have opened with a long continuous shot, starting from approaching the galaxy all the way through to the streets of the Emperor's golden planet.
The script however starts somewhat differently. It follows a ship through space through to the planet Kaitain at the centre of the galaxy, where it lands and Dog-Beings leave the ship, travel through a lifeless city, and enter the "Museum Of Man". Inside they find a giant robot on a crucifix. Pressing a button activates the robot, which projects, through its eyes, the history of humanity onto a screen - starting with the planet Earth exploding...
Quite a departure from Herbert's novel! But it does fit in with some early storyboards by Moebius that appeared in the 1975 French press kit.
