Contemplating what movie to watch this holiday week? You can't go wrong with "When Harry Met Sally," perhaps the greatest rom-com of all time. Nora Ephron, who wrote the screenplay, as well as other great movies and books,  knew just how to make people laugh and cry and kvell. But mostly laugh. She was a successful director and producer too, in an industry not very hospitable to women. In this episode, Ephron shares the most important lesson she learned from her mother: that all pain is fodder for a good story. She explains why becoming a journalist was the best thing she ever did. And she tells stories from her later career in Hollywood, including the one about how the famous faked-orgasm scene in "When Harry Met Sally" came about.
