Is it just me or is Gollum from LOTR and The Hobbit the most realistic CG character?
Gollum is in a movie full of CGI characters and human like races (elves, dwarfs, hobbits) but only 1 is actually human. Gollum is also represented in CGI in all movies. Also because his face is not exactly human but that of a magically altered hobbit, it’s a lot easier to accept how he looks than if it was meant to represent the face of a real life human.
Peter Cushing was a real actor in a movie where all humans are portrayed by real human actors, all the other races are clearly alien and portrayed with puppets or masks. He is then represented with CGI in another movie while surrounded by real actors, it stands out like dogs balls even if they didn’t shove his CGI face directly in the camera multiple times. As commented by someone else, they also didn’t accurately capture his mannerisms. If he didn’t actually say anything when the camera was on his face it would have been much more convincing.
Both him and Leia could have just been done with with them looking away from the camera, even just a silhouette in the case of Leia with her hair buns. Heck, they didn’t even need to show Leia, just have her voice and not even that as you’ve already recognised the ship exterior and interior by then. There were plenty enough clues to figure out who’s ship they were on and what the story was connecting into.
