The broader cast of Dune: Part 1 extends beyond the core household to include agents, advisors, and military leaders whose interactions frame the film’s geopolitical landscape. From council chambers to caravan routes, these performers translate dense narrative structures into recognizable human behaviors, enabling viewers to track alliances, betrayals, and shifting power dynamics.
