" he must try to delete the images associated with David Lynch's 1984 version of Dune from the public's consciousness "
This means no Dune, at least for me. And I actually don't want to forget Lynch's version - it is one of the best movies I ever saw (first time when I was 12 or 13 years old).
IMHO some remakes are not meant to exist. This might be just one of those [ Another one would be a Cronenberg's Existenz remake ].
What will happen ? Probably some high-speed movie with state-of-the-art photography and visual effects, a typical Hollywoodesque movie made for profit. Not a real movie, from my perspective, a movie that I'd go and watch.
Anyway, just my opinion.
