Right now you’d need a artistic/ML mixed team. You wouldn’t use an off the shelf tool. There was a video of some guys doing this (sorry can’t find it) to make an anime type animation. With consistent characters. They used videos of themselves running through their own models to make the characters. So I reckon while prompt -> blockbuster is not here yet, a movie made using mostly AI is possible but it will cost alot now but that cost will go down. Why this is sad it is also exciting. And scary. Black mirror like we will start creating AI’s we will have relationships with and bring people back to life (!) from history and maybe grieving people will do this. Not sure if that is healthy but people will do it once it is a click of a button thing.
