Ingmar Bergman died today. You didn't see him going back to redo his final cuts of his films.
He had more say over final cut than these huge studio pictures do with test audiences and so forth.
I love Dune (the book series) and David Lynch, but I'm still baffled as to which Dune film to watch to get the full experience.
The theatrical cut. Although the whole production and post-production was a messy affair he's stated that he's not going back to it to recut it. I don't even think it's in his hands... he's been tied up with Inland Empire, supervising the second season transfer of Twin Peaks to DVD and other projects. I'd love to see every single film of his carefully re-transferred to whatever HD format comes out king.
