i think lucasfilm is always trying to push technology, taking claim to all the first big technology achievements in movie historyWhy does everyone get so penny pinching in the defense excuses when it comes to Disney? They have more money than most countries do....
A face mask with some miniature animatronics, like something out of Hellboy 2 and the Golden Army's practical effects (near 14 years old now), would have been the way to go, and if they are going to all out DeepFake Luke, they couldn't digitally shift his mouth down a little just like you did to better match the OT and even cartoon?
thats just what i think
