Whenever you're making a movie, especially when you're writing, you always have self-doubts.

After a lot of struggling and sort of reflection I realized that the time you have to give is now, regardless of how old you are.

For 'Star Wars' I had to develop a whole new idea about special effects to give it the kind of kinetic energy I was looking for. I did it with motion-control photography.

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.

The ideals and principles for which Martin Luther King Jr. fought have never been forgotten and are as relevant today as they were 40 years ago.

The first script was one of six original stories I had written in the form of two trilogies. After the success of Star Wars, I added another trilogy. So now there are nine stories. The original two trilogies were conceived of as six films of which the first film was number four.

I've always just followed my own course, whatever I found the most interesting to me at the moment. I've never had a real plan of, "I want to get from here to there, and I've got to do this."
