Define CrewAI Team and Roles

Using CrewAI, define a team of agents for film pre-production. Include roles like 'Film Writer', 'Director/Visionary', 'Visual Style Architect', and 'Production Manager'. Specify their individual goals, backstories, and the tools each agent will have access to (e.g., 'Film Writer' needs Claude Opus 4.1 for creative writing, 'Visual Style Architect' needs an image generation tool, 'Production Manager' needs a cost estimation tool).
