OK before we dive into this, I have to get two things out of the way. Firstly, it can’t rain on Arrakis. That’s like Krypton not blowing up. Rain on Arrakis is so mind altering stupid that is ruins the entire movie that comes before it. Rain kills the worms and thus destroys the spice. C’mon people. Second, the weirding way doesn’t need stupid modules to work. That’s like making the Force the result of microscopic creatures. Sigh.
Back when a scifi movie called “Dune”, which borrowed the name of a far superior novel, was being filmed in Mexico; Sean Young took behind the scenes video of the cast. You can find that video, with her commentary over it, below. Maybe someday we’ll get a real Dune movie.
