The story being told in 'Star Wars' is a classic one. Every few hundred years, the story is retold because we have a tendency to do the same things over and over again. Power corrupts, and when you're in charge, you start doing things that you think are right, but they're actually not.
George LucasIt wasn't long after I began writing Star Wars that I realized the story was more than a single film could hold. As the saga of the Skywalkers and Jedi Knights unfolded, I began to see it as a tale that could take at least nine films to tell - three trilogies - and I realized, in making my way through the back story and after story, that I was really setting out to make the middle story.
George LucasOne of the basic motifs in fairy tales is that you find the poor and unfortunate along the side of the road, and when they beg for help, if you give it to them, you end up succeeding. If you don't give it to them, you end up being turned into a frog or something. It's something that's been around for thousands of years, a concept that's been around for thousands of years.
