Emily Watson stars in this big-budget prequel to the blockbuster films, which is set more than 10,000 years before Timothée Chalamet arrives on the scene. She plays Valya Harkonnen, the mother superior of an order on Wallach IX, who vows to protect the Sisterhood (which will become the Bene Gesserit, the superhuman, all-female “mental and physical school”) alongside her sibling, Tula (Olivia Williams). Thirty years later, a royal wedding, which is part of their plan, comes under threat. Hollie Richardson
