We know and love David Prowse as the towering form of Darth Vader from the original Star Wars series. But U.K. fans might also know him as the Green Cross Man, a superhero created in the U.K. to teach children to safely cross the road. Fan Daniel Nugent met him in 1983, after a then-8-year-old Nugent won a Green Cross Man coloring contest. The prize, besides meeting Prowse? A bicycle.
