Desc: The Late Queen's Mother: Directed by Louis Dubreuil. With Queen Elizabeth II, Vivienne Pettitt, Christopher Warwick, Rob Roy McGregor. Queen Elizabeth II was a woman bound by her duty to the United Kingdom. As the longest-reigning monarch in British history, the late Queen put her own life on hold, ensuring she put country first, remaining the one constant in everyone's life for over 70 years. For 50 of those years, The Queen Mother was by her side. A symbol of the modern royal family, Elizabeth Bowes-Lyon was thrust into the public eye after marrying the future King when she was just 23. For the rest of her life, during wartime and peacetime, through love and grief, The Queen Mother's own sense of duty and optimism would offer stability to both the monarchy and the country she served. These characteristics would live on through her daughter, Queen Elizabeth II, undoubtedly influencing her long and prosperous reign.
