This might be ambitious and may not be something to do, but would you consider asking help from someone very talented and experienced with DeepFakes to fix Leia in the flashback scene. She looks too much like her character model in Battlefront II in there.
That’s Carrie Fisher’s actual face from Jedi, not CGI. I don’t know how an amateur could make it look better using deepfake technology.
It didn’t look like they merged archived material for that scene. If that’s true, could you tell me which scene from Return of the Jedi they pulled her face from? Was it when she was struggling to tell Han that her and Luke were related?
