IMO we're pretty far off from building a single model that can generate a whole film at the press of a button. But I think a more interesting distinction is a model that allows a human to generate professional quality without spending the time or skill it used to take. We've got most of the building blocks -- a language model could generate a 3 act summary, could go from a description of a scene to the text of it, can go from a text description of a character to an image, from an image to a 3d models, etc. Every step needs human intervention and curation, but the difference is it can be done by anyone. As the tools get better they get more control. I think in under a year, anyone will be able to create a 30-page graphic novel that is indistinguishable from human created work without close inspection. It will still take a lot of time and creative energy but they will not need to have an art or writing background. In 5 years, creating a pixar level feature animated film will still take a lot of work, but it will be achievable by, say, a high school movie-making club over the course of a semester, rather than needing a studio of hundreds of specialists over two years.
