When Timothee Chalamet's character Paul first lands on the "Dune" desert planet Arrakis, the son of Duke Leto Atreides is naturally greeted with a crowd. Onlookers, called Fremen, in dark head and face coverings shout in a tongue almost identical to Arabic. Women ululate in the background as they first lay eyes on their white "chosen one," their future leader. "Dune" uses explicit Islamic imagery and cultural elements, experts say. But the main cast doesn't feature a Middle Eastern or North African, aka MENA, actor in a prominent role.
