LYDEN: Jeffrey Friedman and Rob Epstein, you've - two have worked together for a long time. I'd like to hear a little bit about your partnership, how it started.

EPSTEIN: Well, we started working together in 1987. We both had other careers prior to working together. And then Jeffrey was my editor on a show that I was doing - an episode I was doing for PBS. We really clicked; our styles really clicked, and the way of telling stories really clicked. And we decided we would make a documentary together. And the first one was "Common Threads," about the AIDS quilt, which won an Oscar in '89, and that kind of cemented the partnership.
