I’m sure there is some usable stuff in his older movies. They’re not the most popular, but they’re there. Even ones from the 30s when he was younger; could take shots from those and age him up or something, I dunno lol. Anakin’s head is pretty still in the jonh clips too.
Here he is in 1964, in a film called It Happened Here. I’m sure there are a ton of angles in this film alone for just a short few second clip. For a deepfake thing. Just for starters.
