On the basis of his work on the low-budget quasi-student film "Dark Star," future "Alien" writer Dan O'Bannon was hired to create the special effects, after Jodorowksy failed to detect any sympathetic vibes in a meeting with the industry's reigning FX master at the time, Douglas Trumbull ("2001: A Space Odyssey"), whom the filmmaker dismisses as more a "technician" than a fellow truth-seeker.
And second, that in the decade from the late 1960s through the mid-'70s, filmmakers often hatched extreme, unique, original visions — among them Stanley Kubrick's 2001: A Space Odyssey, Jean-Luc Godard's Weekend, Haskell Wexler's Medium Cool, Dennis Hopper's The Last Movie, Dusan Makavejev's W.R.: Mysteries of the Organism, Bernardo Bertolucci's Last Tango in Paris, Werner Herzog's Aguirre the Wrath of God and, we might say, Gerard Damiano's art-porno Devil in Miss Jones.
For special effects, Jodorowsky brought aboard Dark Star’s Dan O’Bannon, rejecting 2001: A Space Odyssey whiz Douglas Trumbull as insufficiently spiritual.
Dune was to be a very European cross between 2001: A Space Odyssey and the rollicking, speedy visuals of the yet-to-be-made Star Wars.
Rejecting special-effects wizard Douglas Trumbull (2001: A Space Odyssey) as being too greedy and arrogant, he drafted Dan O’Bannon, sci-fi novel artist Chris Foss and then-unknown H.R. Giger to design the film’s look.
He rejected Douglas Trumbull, who, after 2001: A Space Odyssey, was considered the most obvious choice for the effects Jodorowsky was envisioning, because he did not have the kind of spiritual connection to the work that Jodorowsky expected his team to have.
