Stunt master Nick Gillard notes in a commentary that Anakin’s style of fighting is really far too aggressive. This is another contrast to the open, compassionate boy he once was on Tatooine. In “The Wisdom of Insecurity”, Watts notes this common problem, as he is not unlike “the sensitive boy who learns in school to encrust himself for life in the shell of the ‘tough guy’ attitude.” It would be difficult to find a more extreme example of the archetypal tough guy than Darth Vader.
