Bottom one is CGI + deepfake, as far as I understand. I don't see how it could be otherwise.
They basically just ran the algorithm on the existing movie scene.
The result is a fairly plausible Carrie Fisher, made more plausible (to my eyes) with deepfake. Obviously it helps that someone already made the original fake Carrie Fisher, because deepfake had to do less work, but it highlights the fact that deepfake could be useful in the industry: Make a plausible CGI version, and then improve it with deepfake.
