Expect hit actors from today to become digitized and immortalized on the screen. Eventually there will be a cannon of standard "actors" (customized per movie of course) that will never change once they settle in on the appropriate archetypes.
This already happens. Around 2010 the actor for the colonel from Avatar had his face digitized for use in sequels. More recently actors from earlier eras have been reincarnated in CGI (Luke Skywalker takes on his original trilogy appearance for the Mandalorian).
This is the premise of the film The Congress, based loosely on Stanisław Lem's The Futurological Congress.
Interesting! I'll have to check that out.
Yeah, but there will be interpolation between them
