Unpopular opinion : Dune part 3 will be nothing but misery porn and not worth bothering with. I liked the Paul-as-basically-a-hero vibe of the first book much more.
I know, I know, shoot me now.
Nevertheless, this detailed breakdown of the sandworm-riding scene is well worth watching. Turns out that Abu Dhabi had the wrong kind of dunes so they build their own.
