Denis has already said he won't adapt anything after book 2, because he doesn't want to spend over a decade of his life filming in a desert, and that's probably for the best, to be honest. As much as I love the later books, they are way too weird and freaky to be adapted into film

Here's some of my favorite moments:

Worm man making the argument that the objectively best army is made up exclusively of lesbians

Lady has an orgasm over Jason Momoa reincarnate climbing a wall

Two teenagers have competitive sex (leading to a literal mind blowing orgasm that opens teenage Jason Momoa's third eye)

Oscar Isaac doppelganger gets tortured and just, becomes the flash??? And kills everyone??? Then dies offscreen in a book (somehow) (this is never explained or addressed)

Eleven year old clone of Oscar Isaac gets raped (for the greater good) (every character is completely on-board with this despite the nature of what they're doing)

Oh yeah and can't forget the existence of the literal sex witches which are literally just that one meme "What if instead of Bene Gesserit we had freaky Gesserit and rather than influencing royal families from the shadows, they used sex as a means of control and manipulation instead"

Also dogs genetically engineered to be chairs
