A new documentary series centred on the life of Princess Diana is in development, with producers promising an intimate portrait told largely in her own voice.

Titled Diana: The Unheard Truth , the three-part series is scheduled for release in 2027, marking 30 years since Diana’s death in a Paris car crash. The project is based on previously unreleased audio recordings of conversations between Diana and her confidante, surgeon James Colthurst. The tapes were originally used as source material for Diana: Her True Story by Andrew Morton.

The series will explore her life, marriage to King Charles III, and legacy, offering fresh insight into one of the most scrutinised figures in modern history.
