There’s a lot of territory to cover in Denis Villeneuve’s Dune movie universe for Max’s upcoming television series, Dune: Prophecy. The series centers on the establishment of the Bene Gesserit religion and is set 10,000 years before the events shown in Dune: Part One and Part Two. Still, Dune: Prophecy has a lot more questions to answer. Naturally, the TV show has to cover a number of important themes that Villeneuve left out of his films in order to properly build up his much awaited Dune 3 as well as for the sake of Dune history.

Key to Dune: Prophecy’s impressive cast of characters are Valya Harkonnen (Emily Watson), the leader of the newly founded Bene Gesserit Sisterhood, and Tula Harkonnen (Olivia Williams), Valya’s sister and fellow Bene Gesserit adept. While the main focus will be on the Harkonnen sisters and other Bene Gesserit acolytes, members of the Corrino Empire will also play a key role. Needless to say, the prequel series sets the stage for Paul Atreides’ (Timothée Chalamet) epic story, but Dune: Prophecy also needs to properly introduce a crucial faction that Villeneuve failed to include in his movies.
