Nicole Kidman is back in the spotlight with her latest film, "Babygirl", where she plays a successful CEO seeking fulfillment from an unsatisfying marriage. In an exclusive interview with correspondent Tracy Smith, Kidman talks about how she chooses such intense and challenging roles and navigating grief over the recent death of her mother. She also opens up about family life with husband Keith Urban and the benefits of working with women writers and directors. But it hasn't always been easy - at one point, Kidman almost gave up acting altogether. Through it all, she remains a force to be reckoned with in Hollywood.
