One change we can understand – in The Phantom Menace Yoda was a puppet (much like his previous two appearances), but compared to Attack of the Clones and Revenge of the Sith where he was CGI he just looks wrong. So now he’s been redone as CGI and looks TONS better. Take a look:
Updated Yoda (skip to about 0:12 to see the difference):
But wait, there’s more! It appears that the Ewoks can blink now with the help of CGI eyes – but they still look like kids in winter sleepers.
But perhaps the most jarring change being reported (and supposedly confirmed) is that in Return of the Jedi, during the the scene where the Emperor is torturing Luke, and there is a rather silent Darth Vader looking on before he decides to take action, Vader now gives first a subdued “No”, followed by a more drawn out “Noooooo!”. This does kind of fill in the “awkward pause” and perhaps lends a bit more to Vader’s crisis of conscience, but does it work? Here is what appears to be the scene from a leaked copy of the Blu-ray:
Does it work?
