Denis Villeneuve has put together one of the greatest casts for a film and it just keeps getting better and better.

Josh Brolin is the latest name to join Villeneuve’s upcoming Dune film that will be led by Timothee Chalamet. The film also has Javier Bardem, Rebecca Ferguson, Stellan Skarsgard, Dave Bautista, and Charlotte Rampling, with Oscar Isaac and Zendaya in talks to join.

Brolin will portray Gurney Halleck, the warmaster for the Atreides family and a mentor to Chalamet’s Paul Atreides. Patrick Stewart played the role in David Lynch’s 1984 movie adaptation.

Villeneuve is directing and co-writing the script with Eric Roth and Jon Spaihts. The movie will be produced by Villeneuve, Mary Parent, and Cale Boyter, with Brian Herbert, Byron Merritt, Thomas Tull, and Kim Herbert serving as executive producers. Kevin J. Anderson will act as a creative consultant.

Set in the distant future amidst a feudal interstellar society in which various noble houses control planetary fiefs, Dune tells the story of young Paul Atreides, whose family accepts the stewardship of the planet Arrakis. While the planet is an inhospitable and sparsely populated desert wasteland, it is the only source of melange, or “the spice”, a drug that extends life and enhances mental abilities.

Brolin and Villeneuve worked together on the critically acclaimed 2015 crime drama Sicario. Brolin recently reprised his role in the sequel, Sicario: Day of the Soldado.
