The TV version had the prologue that is really good.
I wasn't sure about Kynes being cast as a black female, but if she can pull it off, go for it. Kynes falls in that area of 'important, but not too important' for those kinds of changes. If it comes with an otherwise properly budgeted and directed Dune movie, I'll take it.“What Denis had stated to me was there was a lack of female characters in his cast, and he had always been very feminist, pro-women, and wanted to write the role for a woman,” Duncan-Brewster says. “This human being manages to basically keep the peace amongst many people. Women are very good at that, so why can’t Kynes be a woman? Why shouldn’t Kynes be a woman?”
I can get behind a tweak for Baron Harkonnen too, and I kind of agree with his assessment. I just hope those are the only major cast adjustments.This version of the character is less of a madman and more of a predator. “As much as I deeply love the book, I felt that the baron was flirting very often with caricature,” says Villeneuve. “And I tried to bring him a bit more dimension. That’s why I brought in Stellan. Stellan has something in the eyes. You feel that there’s someone thinking, thinking, thinking—that has tension and is calculating inside, deep in the eyes. I can testify, it can be quite frightening.”
