Jason Momoa is in negotiations to join the cast of Denis Villeneuve's film adaptation of Frank Herbert’s bestselling novel Dune.

If a deal closes, he would join a cast that includes Timothee Chalamet, Javier Bardem, Rebecca Ferguson, Stellan Skarsgard, Dave Bautista, Josh Brolin, Oscar Isaac and Zendaya.

Momoa will portray Duncan Idaho, a swordmaster in the house of Atreides who is the right-hand man to Chalamet's father, played by Isaac.

Set in the distant future, Dune tells the story of Paul Atreides, 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 the 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.
