If you’re listing samples in the main post, you might as well link to these:
Young Ian McDiarmid on Rey’s Dad: https://www.youtube.com/watch?v=rjT1DhfTIoo
Palpatine clones on Exegol: https://originaltrilogy.com/post/id/1340464/action/topic#1340464
I can’t tell any difference from the original on the Rey’s Dad one, I’m afraid! Still, a good find that someone has at least attempted it.
