I must say, though, that while Boorman's film would have grossly misrepresented Tolkien's novel, it's at least recognizable as the same story. I'm not sure the same can be said for what Jodorowsky would have done to Herbert's DUNE. One thing people connected with the project say over and over in the interviews in this documentary is that they'd never read the novel, knew nothing about the original book, and apparently never did bother to look up the story they were supposed to be adapting. That's probably because 'adaptation' really doesn't begin to describe Jodorowsky's approach, as when he proudly proclaims:
"I change the end of the book . . .
It's different. It was my DUNE.
When you make a picture,
You must not respect the novel.
. . . I was raping Frank Herbert"
*He's since blogged about it:
**literally: he says in this documentary he wanted viewers of his film to experience all the effects of being high on LSD without actually taking the drug.
