There’s a story, it might be apocryphal, about how George Lucas went to Toshiro Mifune to offer him the role of Obi-Wan Kenobi in “Star Wars.” It makes sense, right? It’s widely known how Lucas was inspired by, and cribbed heavily from, Akira Kurosawa’s “The Hidden Fortress,” the star of whom is Mifuni of course, and what with the robes and the swords and that “Obi-Wan Kenobi” is nobody’s idea of an obvious nom de plume for Sir Alec Guinness, Mifune.
