Although few knew he was under that iconic helmet, the actor who put the swash in Darth's buckle passed away:

RIP, Bob Anderson.
Bob's sword choreography was a big part of the awesome epicness of the original trilogy for me. It made me want to take up fencing in college. He can be seen working with the actors in some of the behind the scenes stuff. Rest in peace Bob.
