In fact, I wasn't going to dance in Xanadu, but several journalists told me that Olivia Newton-John kept saying how sad she was that she wouldn't get the chance to dance with me. So I finally said, "All right, throw in a number." But I'm through with dancing.

Things danced on the screen do not look the way they do on the stage. On the stage, dancing is three-dimensional, but a motion picture is two-dimensional.

I had been asked to open a nightclub in Atlantic City. They offered me a ridiculous amount of money. They literally overpaid me. So I did one show a night. Then they asked me back by popular demand. So I went back. Then I said, "To hell with this." I was only doing it for the money, and I was doing easy routines. It's just too much work to get up every day and practice.

I didn't want to be a dancer... I just did it to work my way through college. But I was always an athlete and gymnast, so it came naturally.

The way I look at a musical, you are commenting on the human condition no matter what you do. A musical may be light and frivolous, but by its very nature, it makes some kind of social comment.

First of all, break-dancing has been done for years, though not all of it put together the way it is now. But, actually, the distinctions have been blurring since the 1950s.

When they do let them sustain on screen from head to toe, though, then you know they must think the person is a good dancer.
