MICHAEL OVITZ: To be a great agent in those days, you had to be a mini-expert on the beginnings of any subject. I had 250 magazine subscriptions. I was a strong believer in general knowledge. Every time I went to an event, an opening, a dinner, or a meeting, I was given a short briefing card on one of our buck slips by one of my assistants, and it generally had everything I needed to know.
