💩The still suits in the Dune franchise are designed to recycle not only sweat but also urine and feces for survival in the desert.
🌵The Fremen population in Dune live in waterless deserts and rely on still suits, as well as their knowledge of the environment, to survive.
🤢The explicit mention of the still suits' waste-processing capabilities was omitted in the film adaptation of Dune, possibly to avoid disgust from viewers.
👑The villains in Dune, such as Baron Vladimir Harkonnen and Feyd-Rautha Harkonnen, are depicted as visually repulsive, while the heroes, like Paul Atreides, are portrayed as attractive.
🚽Although not explicitly shown in the movies, the mention of the still suits' waste-processing function could detract from the visual impact of the villains' repulsiveness.
