"I know my mother and she is just terrific, and I have such admiration and respect for her. She's such a character, too. I really think she's one of the great untold stories, not just because of all of the events she's lived through," Rory Kennedy said. "But also because she's just such a wonderful person, and I hope that comes across in the film. She's so funny, and she is such an inspiration to me. Our family knows my mother, our close friends know her, but to be able to share her with so many other people I think was important."
