The late Pulitzer Prize-winning playwright Wendy Wasserstein was a lovely person whom I had the privilege of knowing. And I was fortunate enough to interview her twice on her script writing process some years ago, at the Dramatists Guild in NYC and at Drew University where I was teaching at the time. Both were in front of rather large audiences. She was a straight shooter and told it like it is regarding her writing and how she managed to create so many successful plays.
You can find a condensed audio version of my Guild interview with her on the Guild website here. She offers many words of wisdom to the script writer.
