In the future, realtime graphical rendering will be advanced to the point that no movie will need to be produced using live action. Any plot, actor, animal, location, or prop will be rendered at will according to the preferences of the end user. Don’t like Matt Damon in a movie but do like Ben Affleck? Download the Affleck package (combining animations, skins, and voice patterns), insert into the movie, and there you go. Fancy changing the macguffin from a cosmic cube to a rubber ducky? Swap the prop preference, and wham-o!
