As reported by Deadline, the docu-series Unheard Truth (working title) focuses on five hours of exclusive audio where Diana speaks candidly about her complex reality within the royal family. These tapes offer her unfiltered thoughts on her former husband, King Charles III, and his wife, Queen Camilla. The narrative aims to move beyond the traditional portrayal of Diana as a mere victim of her difficult circumstances.

Only a small fraction of this audio has ever reached the public. This project provides a rare opportunity to hear the Princess describe her own life in her own distinct voice.
