When Oscar nominee Diane Ladd developed a life-threatening illness, her doctors recommended exercise to rebuild her lung capacity. That prompted a series of long walks and long conversations with her daughter, Oscar winner Laura Dern. Their recorded conversations have now become a joint memory, “Honey Baby Mine: A mother and daughter talk about life, death, love (and banana pudding).” They speak with correspondent Rita Braver about a family story playing out on TV and movie screens (sometimes even playing mother and daughter) and about the challenges they’ve faced (along with so many working single moms).
