I was thinking about this the other day as my family was watching the Obi Wan TV show. Darth Vader is in it, and he's a composite of I think only two actors this time; Hayden Christensen doing the physical performance, and a James Earl Jones-trained voice filter on him when he was in full costume. James Earl Jones got a line in the credits, but I'm not sure he read any lines. Got me wondering if LLM technology and its successors might yield fictional character/actor composites that no longer correspond to physical people anymore, Hatsune Miku, or Gorillaz-style. If there will be a time when Darth Vader is credited as being performed by Darth Vader. He already is a composite as it stands. When too for the Marvel cast?
