In the 1980s movie "The Running Man" there was a scene where the two main characters were replaced by two others, those made to look like the two runners, they were killed.
My late father did not understand how that worked, so I explained that computers faked it so the two people looked like other people. He found that unsettling.
How can anyone possibly trust what they see on the news with today's fake-it technology?
Yeah, we can see examples of that in movies and TV already.
Mark Hamill's younger face being superimposed on his older self for Luke Skywalker scenes in the latest Star Wars media, background actors and actresses having their likeness unknowingly (and illegally) scanned for use as background CGI extras, et cetera.
(There's also the Mandalorian scene with Ahsoka and Grogu, but you get my point there).
And Leia in the earlier Rogue One, though she suffers from a bit of Uncanny Valley.
Terminator: Salvation had an earlier example of it with the T-800 RIP.
I mean, Terminator: Genisys had it with early 80's Arnold's face on one T-800 (supposed to be the original Terminator from Terminator 1), and early 90's Arnold on "Pops" (using the face of Terminator 2's "Uncle Bob").
Even Woke Fate used it for the T-800 ("Carl") that killed John at the start (and look how far the technology has come since Salvation in '09!)
It's just going to keep getting better and better as companies refine it... And it's a Pandora's Box that's already been opened.
On the one hand, we may see classical actors now departed reprise their roles with AI speech and likeness, such as Christopher Lee (with their respective estate's permissions, of course); on the other hand, Pandora's Box, studios pissing on these actors' legacies with subpar bullshit releases, et cetera.
