Pam has always been my glamorous big sister - 13 years older than I. She played on the women's circuit for nine years and came home to tell me stories of France, Japan.

I was planning to remain an amateur for a while.

To meet my goals, I couldn't let up when I was playing tennis.

From one match to the next, I kept on winning.

My research interests since then have shifted strongly towards the economic and regulatory problems of the financial services industry, and especially of the securities and options exchanges.

I think we have a responsibility to shape the zeitgeist with the movies we put out there. Because 'After Earth' isn't going to do it. 'The Expendables 3' isn't going to do it. You could make one million amazing films for the amount of money they spend on those films. I get frustrated.

The thing that happens is that politicians run on tough-on-crime rhetoric. You appeal to the public and say, 'Let's put more money into taller fences, tougher laws, tougher sentencing, handcuffs,' and where does that money come from? Well, immediately, it comes out of all the money needed for corrections.

I said I would do all the films about the commercials, and the films about ball-bearings and Ford tractors and so on, if once a year they gave me money for a free film.
