Is it the voice that makes the character, though? Can I take any middle aged Stanley type from the office and get the ai to place the voice as the next Taylor swift? Is it then actually the original character/ actor? Why not just synthesize the looks according to whatever teenage adolescent fantasy the marketing department wants and fully program the character, i.e. a fully artificial actor, instead of basing it off some persons looks? The former cannot possibly have legal repercussions, but if the latter, by all means, protect the actors rights and likeness from abuse.

I think the studios still need the actors to perform the characters, because the ais can't emote. But once they can, it's over for the actors
