So who else was there? Bob Anderson had been Britain's Senior National Fencing Coach for thirty years. Anderson doubled for David Prowse in Empire's dueling sequences but also helped choreograph the fights. Vader seems to meet all the criteria for the perfect space villain on the surface- deep voiced, black clad, heavy breather and built 2m high for battle. He employs his extra sensory powers to keep Emperor Palpatine in power. Vaders 'dark side' aids Governor Tarkin in the destruction of the rebels. In 1980 Star Wars "Empire Strikes Back" becomes the 'Years Best Movie' exposing an inescapable truth between Darth Vader and Luke Skywalker.
Remember, Darth Vader is Master of the Dark Forces and wants you!
