Lucas told reporters he envisioned the first three films, which began with "Star Wars" in 1977, as entertainment about the children of Anakin and Senator Padme Amidala -- Luke Skywalker and Princess Leia Organa reports Reuters..

The final three films that began with "Star Wars: Episode I - The Phantom Menace" in 1999, tell the parents' more conflicted tale. "I knew this would be a more mature look at the story," Lucas said.

At a film conference in Las Vegas during the month of March Lucas said "It's a real tearjerker, and it will be received in a way that none of us can expect. I feel that I've made the movie the best I can and it turned out the way I wanted it to be, so I'm happy,"

"Obviously, fans would love to see a movie about Darth Vader running around killing people. I'm not telling that story, and I'm not interested in that. That's not what the movie is.

"This first trilogy is really about the father, the struggles of a father, or a man, basically, to find himself, and at the same time fall into a trap of wanting certain powers, making a pact with the devil and basically spending the rest of his life regretting it."
