I've storyboarded on some big films. There's no "sanctity of the art" on a film. Infact most of your drawings end up in the trash. They are entirely disposable pieces of working media designed to communicate an idea. The art is in sequence design, not drawing. You ABSOLUTELY want to streamline this process. You want to empower sequence designers with the simplest and fastest method of keeping characters on model, and iterating ideas. You want to empower storytellers, not just "good drawers". The fact that people who can "draw good" are the only ones let into the room that defines the cultural narrative of humanity is a grave injustice. The stories that need to be told aren't only the stories of those with a mastery of drawing. Everyone's story deserves to have the opportunity to be told. Storyboarding isn't primarily art, but language. And language belongs to everyone. For reference, here's one of Scorcese's own boards. No one could accuse it of being art, yet it served as a functional blueprint for what would become a great film. AI allows more filmmakers to work faster, iterate more quickly and communicate to collaborators at a higher fidelity.
