Acting as a graphic designer, ask the AI to generate ideas for a series of posters for a film franchise. Each poster should highlight a different film in the series, maintaining a cohesive visual style that ties them together. Specify key elements, such as the color palette, imagery, and typography, that should be consistent across the series. Additionally, request that each poster captures the unique theme or tone of its respective film while still aligning with the overall franchise brand.
