Audio recordings of Princess Diana will be heard for the first time in a docuseries exploring the People’s Princess’s “Unheard Truth.”

Producer Love Monday has unearthed secret taped conversations Diana had with her friend James Colthurst in 1991, which became the foundation of Andrew Morton’s book Diana: Her True Story. Love Monday has partnered with Morton and Colthurst to secure full and exclusive access to five hours of the tapes for Diana: The Unheard Truth [working title], which the creative team said will “challenge the reductive narrative that has too often framed Diana as a victim of her circumstances.” In the three decades since Diana’s death, less than one hour of these tapes has been heard.

The tapes will reveal Diana’s thoughts on her ex-husband Charles, now King Charles III, his wife Camilla, and even Andrew Mountbatten-Windsor, who then was Prince Andrew.

The doc, which is now being shopped worldwide, will also feature perspectives from those closest to Diana including Delissa Needham, a prep schoolmate who has never spoken on camera before; Sam McKnight, the hairdresser who was with her throughout the nineties, trusted even to cut her sons’ hair; Penny Thornton, the astrologer to whom she turned for guidance, and Richard Kay, the Daily Mail journalist who found himself Diana’s confidante.
