Oscar Isaac as Duke Leto Atreides
The glorious beard attached to the face of the equally glorious Oscar Isaac is playing Duke Leto Atreides, Paul’s father and the lover of Lady Jessica. Jessica was meant to be Leto’s concubine while he married into another powerful family in the Imperium, but the two fell in love. In Dune, he’s tasked by the Empire with becoming the steward of the planet Arrakis, taking over from a villainous figure we’ll meet in another poster later.
