If anybody is even remotely skilled at deepfaking I’d imagine that dark Rey’s eyes could be taken care of rather easily. Yes, you’d be deepfaking Daisy Ridley’s face onto Daisy Ridley’s face but based on what I understand the eyes would be normal again once finished. Might be something I’ll look into myself eventually if it’s all we are waiting on.
I don’t know how deepfakes work, but I think it needs the info on the eyes to overlay the ‘new’ eyes, it might have a hard time with the white eyes (if it gives her pupils at all). I mean a lot of deepfakes I’ve seen struggle with having wobbly eyes as it is, even when the original footage has regular eyes, seems like it’s the hardest part to get right.
