Denis Villeneuve (Sicario, Arrival, Blade Runner: 2049) is bringing Frank Herbert’s Dune back to the big screen for Legendary, potentially with a series of *at least* two movies. Timothée Chalamet and Rebecca Ferguson were the first to get on board, with Dave Bautista and Stellan Skarsgård added to the cast just last week.

THR now reports today that Charlotte Rampling (45 Years) has signed on. She’s set to play the Reverend Mother Mohiam, the emperor’s truthsayer.

“Set in the distant future, “Dune” tells the story of Paul Atreides (Chalamet), whose family accepts control of the desert planet Arrakis. As the only producer of a highly valuable resource, control of Arrakis is highly contested among competing noble families. After Paul and his family are betrayed, the story explores themes of politics, religion, and man’s relationship to nature as Paul leads a rebellion to restore his family’s control of Arrakis.”

Villeneuve wrote the script, along with Eric Roth and Jon Spaihts.
