Having rewatched the latest episode I now see what people mean by Luke’s moth moving a little unnaturally, though its still much better than RO Tarkin IMO. You can even see that they’ve tried to work around that shortcoming in the edit. However, now that the surprise of seeing the de-aged Hamill isn’t there anymore and I can simply watch the scene, I actually think they did a pretty good job with the de-aged face. I don’t think the effect is soulless like some have suggested, it’s rather just Luke being very serious in the scene. There’s actually some really nice subtle expressions, like his final little nod to Din before he takes Grogu away. I also think it’s important to keep in mind that this is Jedi Master Luke and he doesn’t know any of the main characters so he’s being (for lack of a better word) “formal”. The effect is a little “soft” around the edges at times, but for the most part I think it looks really good. And now that Jeans Guy has been removed, should they choose to polish the effect a little more in the future, they could always add it to the episode without most people really knowing of caring.

I do wonder how they de-aged the voice though. I know how deepfakes and such work fairly well, but this is the first time I’ve heard a voice de-aged.
