Already pretty star-studded, 'Dune' and its cast is still ever expanding. In addition to the confirmed cast, led by Timothée Chalamet and Javier Bardem, Rebecca Ferguson, Stellan Skarsgard, Dave Bautista, Oscar Isaac, and Zendaya, are now Jason Momoa and Josh Brolin.
-- Momoa will play Duncan Idaho, a swordmaster in the house of Atreides who is the right-hand man to Chalamet’s father, played by Oscar Isaac.
-- Brolin will play Gurney Halleck, the warmaster for Chalamet’s family and a mentor to his character.
This is allegedly a two-part movie, and I'm not entirely sure but at the very least the first begins production in March, directed by Denis Villeneuve.
