This new documentary focuses on a defining moment in the British consciousness - the funeral of Diana, Princess of Wales - and tells the story of the day through the memories of those who played a part in it, many of whom are speaking for the first time. Marking 20 years since the funeral on September 6, 1997, the documentary provides a minute-by-minute account of what went into a day when a million people lined the streets of London, while more than 30 million watched on British television and 2.5 billion around the world. Narrated by Kate Winslet, this film tells the story of that day from the chime of the tenor bell marking Diana’s departure from Kensington Palace on a lonely gun carriage to the remarkable journey of the hearse along a deserted motorway to her final resting place at her family home of Althorp. Those interviewed include Sir Malcolm Ross, the senior Buckingham Palace courtier who was responsible for the planning and execution of the funeral in just five days; Captain Richard Williams, the chief pallbearer; Martin Neary, the musical director of Westminster Abbey; Graham Craker, Prince William and Prince Harry’s former Royal Protection Officer; Lisa Webb, who arranged the floral tributes from the two young princes for their mother’s coffin; as well as reporters, police and some of the people who joined the crowds. Their extraordinary testimonies are illustrated with archive footage from the time, some of which has never been seen before. The writer and director of the programme is multi-award-winning filmmaker Leslie Woodhead, whose previous productions with Finestripe for ITV include the Bafta-nominated The Day Kennedy Died and The Day They Dropped the Bomb.
