My Conversation with Sean Penn

Sean Penn has been called the best actor of his generation, taking another step toward that distinction last night by winning his second Oscar for Best Actor.

Off screen he is of course well known as a passionate advocate on behalf of so many worthy causes. Recently, I sat down with the normally press-shy actor to talk about a number of subjects, including how he views his role as an advocate.

The full conversation airs tonight on PBS.
