Central point: there are more reasons than you think that this franchise was considered unfilmable.
Let's start with the source material...
And it's not a book that eases you into it. This is hard, layered, adult sci-fi... until it becomes pseudo-spiritual fantasy. Or both.
It's a lot.
And here's where we have to talk about coding and themes.
Dune says hold my gom jabbar.
Most adaptations will never go that far and then frame him as a hero... despite his genocidal plans.
If I was a producer who read the text, let alone the subtext, I would run SCREAMING from this!
Some of this made the translation through Lynch's adaptation, but trust me when I say it gets WAY worse. So much sexual assault and ugly queer-coding...
But if you take out that detail, the fans and purists RIOT.
And yet for a story of this scope, you need a big budget. See the massive quandary here?
Just warning you all this will be thinkpieced to death by the first trailer. It's already starting.
(yes, I see the irony here) /end
