A few months ago, someone posted a link on the Star Wars thread called starwarshelmets.com. I had a look and there were many Darth Vader helmets on there from each of the original trilogy. There were quite a few noticeable differences in the overall look of Vader's helmet in the three movies, and replicas have been made of each. Now Episode III is in cinemas, does anybody else out there think there is a different look yet again to his helmet? I think the arch over the tops of the eyes is quite wide compared to the original trilogy. There may be other differences you may have spotted. And what would be the reason for the different designs in each movie, from the story's point of view? Does Anakin periodically change his wardrobe, or upgrade his apparatus?
