The man who did the light saber fighting for Darth Vader is dead at the age of 89. While we all suspected that a stunt man was doing these scenes, we now know who that stunt man was.
While James Earle Jones did the voice and David Prowes was the actor, it was Bob Anderson who did the actual sword fighting. And even though he was in his sixties at the time, he proved to be up to the challenge.
Rest in peace Bob Anderson, you will be remembered.
