We already have movies where none of the characters on screen exist outside of that. We call them cartoons. We already use computers to draw them on rather than by hand. Having the computers generate them seems to be the next logical step on that chain.
I do agree that I don't want to see this taking over making films with real people, but I can also understand the appeal of this to moviemakers. No stars demanding script changes, no risk of actors having injuries, no one turning up late to set or being difficult, no big paychecks for a headline name. For a studio, there must be a lot of temptation right there. Even if it costs the same as a normal film, you still run less risks in the making of it and it is a hell of a lot easier to reshoot scenes. No trying to bring back actors who are already working on another movie, or have grown a mustache in the meantime etc.
It will all be down to us though and if we all go and pay money to see them. I'd suspect if watching an AI-generated movie was made cheaper than one with real people it would be successful and replace traditional movies.
I dunno....
While characters tend to have legs, the names behind it all tend to have a lot to do with attracting people to a movie...
Maybe, but I know for me I don't go to see a film because of who was in it. I go to see a film because the story seems interesting to me. Sometimes I even prefer it when it doesn't have big names that I recognise.
