"When you look for the motivations you always go to the basic instincts, to the basic emotions, the basic things that have moved humankind always. That's what all writers write about, ultimately. What did Shakespeare write about? Jealousy, love, sex, power, greed, the same stuff that soap operas and the Bible are made of. It's always the same."
