A unique celebration of the Queen's ninety years as she reaches her landmark birthday in April. Film-maker John Bridcut has been granted special access to the complete collection of Her Majesty's personal ciné films, shot by the Duke of Edinburgh and the Queen herself, as well as by King George VI and Queen Elizabeth The Queen Mother. Much of it has never been seen publicly before. Various members of the Royal Family are filmed watching this private footage and contributing their own personal insights and their memories of the woman they know both as a member of their own close family and as queen. Among those taking part are the Prince of Wales, the Duke of Cambridge, Prince Harry, the Princess Royal, the Duke of Kent and his sister Princess Alexandra, who has never before given an interview.

In August 1997, the tragic death of Diana, Princess of Wales, stunned her family and catapulted the British public into one of the most extraordinary weeks in modern history. What was it about Diana that resulted in such an outpouring of grief? And what does that week reveal about Britain's relationship with the monarchy, then and now?
