Their predecessors were the Harkonnens, with whom they’ve had a bitter feud with for multiple generations. The film covers the first part of the novel of the same name (originally published in 1965 by author Frank Herbert) where our main character Paul ( Timothée Chalamet) travels from his homeworld of Caladan to Dune as his family was given command of the planet to continue export of the spice Melange, the most important substance in the whole Imperium. Dune is a sweeping sci-fi epic that’s influenced dozens of well known properties (hello Star Wars, Blade Runner, Stargate, etc.) and follows the story of Paul Atreides, heir to a dukedom as he and his family are thrust into a dangerous position as the new stewards of the desert planet Arrakis, also known as Dune.
