Sure, in the first three Star Wars films, i.e. the three most recent releases, the news that Yoda would be digitally recreated to augment the awkward puppeteering of Phantom Menace, Attack of the Clones and Revenge of the Sith can be met with cheers. The jeers have been arriving since news broke about several iconic scenes being changed for the films' September Blu-Ray premiere.
For instance (and check out the video below), during Return of the Jedi, as Darth Vader watches The Emperor electrifying Luke, Lucas has now inserted a voice over with Vader yelling “No!”
Another facet of the film series that must have gotten Lucas’ goat is the fact that the technology in 1983 didn’t allow the Ewoks to blink. So, that has been fixed.
Most profoundly, in A New Hope, Lucas has altered the Han shot first scene, also known as the Greedo scene. How? You’ll just have to watch below.
