Desc: The Queen at 90: With Sophie Duchess of Edinburgh, Elizabeth McGovern, Rhiannon Mills, Prince Edward. "Downton Abbey" star Elizabeth McGovern narrates an intimate look at the life and reign of Queen Elizabeth II as we celebrate Her Majesty's 90th birthday. Featuring interviews with members of the royal family, this documentary is a more-than-intimate look at Queen Elizabeth II on her 90th birthday. It is also a story of inspiration and duty. We discover how the Queen supports her family in their public and private lives as she continually does her official duties.
