He is unfortunately correct, if the AI generated actors are convincing enough then majority of people will not care. Just like it is with CGI, people complain about CGI in movies but as examples they can only list movies with very poor CGI because our brain ignores good CGI.



Models can be retrained, there’s a certain website out there that prides itself in having more than 300k movies available for download, if the AI companies get their hands on it then there’s enough training material for them and the outcome will likely be good enough for the average Marvel movie.
Also, they won’t generate a 2 hour movie, they’ll likely do 1 scene at a time and piece it together. So in theory they can carry even a 10 hour movie if the plot for it exists.
