Star Wars' apparent influences range from spaghetti westerns to Kurosawa's samurai dramas — but the story may actually be a bit more mundane than George Lucas would have us believe.

Lucas's movie may have the thoughtful duels of a samurai flick, but chances are good that Luke's lightsaber only glows blue because it looks cool.
