I felt that one of the major issues in the third film is that Luke is finally on his own and has to fight Vader and the Emperor by himself. If you get a sense that Yoda or Ben is there to help him or to somehow influence him, it diminishes the power of the scene.

You simply have to put one foot in front of the other and keep going. Put blinders on and plow right ahead.

When you get a small group of fans who hate something, it becomes compounded by the internet. The press picks up the internet like it's a source. They don't realise it is just one person typing out their opinion.

When Star Wars became a hit and I had a chance to make the other movies, I had to figure out a way to bring Ben back, but a lot of the issues he had to deal with were carried by Yoda. In a sense, I combined Yoda with the spirit of Ben. I wanted Ben to have some kind of influence, but I didn't want it to be a direct influence where he could help Luke. So Ben has managed to keep his identity after he became one with the Force. One of the things he was doing on Tatooine besides watching over Luke was learning how to keep his identity after he became part of the Force.

Obviously, people have a lot of different dreams of where America should be, and where it should fit into things. Obviously, very few of them are compatible, and very few of them are very compatible with the laws of nature.

Good luck has its storms.

If you want to be successful in a particular field or endeavor, I think perseverance is one of the key qualities. It's very important that you find something that you care about, that you have a deep passion for, because you're going to have to devote a lot of your life to it.
