HBO has announced it is reviving (with its original cast) Lena Dunham’s raw, brash and controversial series “Girls,” which from 2012 to 2017 documented the lives of twenty-something friends trying to make it in New York City. In this March 10, 2013 “Sunday Morning” story, Tracy Smith went behind the scenes of shooting, and talked with Dunham, and co-stars Allison Williams, Zosia Mamet and Jemima Kirke, about what made the show’s characters both intriguing and alienating.
