Valya Harkonnen is the leader of the Sisterhood, a group which will inevitably evolve into the faction that the movie fans know better as the Bene Gesserit. Emily Watson will be the lead of Dune: Prophecy alongside Olivia Williams, who plays Valya’s sister Tula Harkonnen. The siblings are adversarial by nature, but work to maintain a unified front for the sake of family and for the good of their people.
While many fans may think of the Dune franchise being classics of the sci-fi genre, some might be unaware just how long the books have continued on since the originals created by Frank Herbert. While the original Dune was published in 1963, Dune: Prophecy is actually based off of Sisterhood of Dune, which was published in 2012. Unlike the previous novel, this will mark the first time anyone has attempted to do an adaptation of Sisterhood of Dune.
