History Fridge / Dune2021

* After Duncan returns from his excursion among the Fremen, he's clean-shaven, whereas Duncan had a beard when he left Caladan (and actor Jason Momoa habitually sports one). With the mouth filter on a stillsuit, while experienced users like Silgar can maintain a beard while wearing them, for a newbie to Fremen ways like Duncan, shaving the beard off would be easier.

* The portrayal of House Harkonnen and all inhabitants of Giedi Prime as [[AlbinosAreFreaks creepy bald albinos]] with massive pupils makes sense from a logical standpoint and not just to make them ObviouslyEvil. Giedi Prime is established as heavily polluted world so filled with smog and smoke that the sun never seems to penetrate. So over the centuries of humans living there they would eventually develop pale skin (due to lack of sunlight), no hair (due to all the pollutants in what they drink, eat, and breathe; keeping their heads shaved would also make it easier to keep clean) and massive pupils (in order to see better in such a light-poor world). Forcing the planet's inhabitants to conform in their appearances would also decrease their individualism, thereby rendering it easier for the Harkonnens to control and oppress them, in contrast to how the Atreides allow their troops to express themselves through different hairstyles.

* When Leto presses his signet in wax to accept the stewardship of Arrakis, you can see the Bene Gesserit scowling. He has literally sealed his fate.

* Some Fridge NightmareRetardant with the Baron’s hovering. Its rather unnerving... until you remember he has the hover tech because he’s too fat to move normally.

* In the book, the Sardaukar taking part in the assault on Arrakeen disguise themselves as Harkonnen or Atreides troops to sow confusion and hide the Emperor's role in the battle. In the movie, they go into battle as they are, making no attempt to disguise themselves. This jives with the orders Liet-Kynes is given to "[[YouDidntSeeThat see nothing.]]" The Emperor is so powerful he doesn't even need to disguise his troops, simply make everyone on the planet too afraid to speak up about what they saw, lest they get the knife next.

* Jessica notes the Bene Gesserit have been to Arrakis and prepared its people to be receptive to members of their order. Later the Reverend Mother asks that the Baron allow Jessica and Paul the dignity of ''exile''. He thinks he's being clever by sending them in the desert to die, but considering the Reverend mother knows about her order's preparation of Arrakis, and specifically asked for exile, he's basically doing what she expected.

** Also, the first piper that comes out of the ship plays his bagpipe in the ''Arabic'' scale.

* When you think of it, it makes perfect sense for Kynes to be the one character gender-swapped into a woman in the adaptation. Within the books, men hold every visible position of power, but the women (most of them Bene Gesserit) pull the strings behind the scenes and in many ways, are the real movers and players of the long game. Which is... kind of what Kynes does: he pretends to be just an official of some local importance and little standing, while running a secret long-term project behind the backs of nominal authorities.
