A film is not one prompt. It is a thousand decisions made by people who know their craft.
Auteur runs the departments you define. A writer's room that argues about structure. A director that holds the intent. A cinematographer that plans coverage. An editor that kills the darlings. Add, remove, or rename roles — the crew works in parallel, hands off, and answers to you.
It is the same shape as an agentic coding tool, pointed at cinema instead of code: long-horizon work, self-review, and a real artifact at the end —production-as-code, fully versioned; not clip, not a cut, a full production.
