HBO just picked up a new pilot from Judd Apatow and former Undeclared writer Lena Dunham, which Dunham will direct and star in. The as-yet-untitled show will be “about the assorted humiliations and rare triumphs of a group of girls in their early 20’s.” Most recently, Dunham won the top narrative prize at Sundance for Tiny Furniture, which she wrote, directed and starred in. Oh, did I mention she’s 24? How old are you again? And what have you done with your life?
