Market news
Cineflix Rights acquires international sales and will present Diana Unheard at MIPCOM
Deadline reports that Cineflix Rights has acquired worldwide sales rights for Diana Unheard and will make the series a key factual launch at MIPCOM in Cannes. The three-part show was produced by Love Monday TV, the UK indie behind recent monarchy-focused factual programming, and will be shopped to international buyers by Cineflix at the market.
Source material
Producers secured previously unheard 1991 recordings used in Morton's book
Love Monday TV secured access to secretly taped conversations Princess Diana had with her friend James Colthurst in 1991. Those recordings formed the foundation of Andrew Morton’s book Diana: Her True Story. Love Monday worked with both Morton and Colthurst to obtain several hours of the tapes, and Deadline reports that Morton and Colthurst appear in the documentary series.
What’s on the tapes
Diana speaks candidly about her life, loves and the royal family
According to Deadline, the audio captures Diana in revealing form as she discusses Prince Charles and Camilla — now King Charles III and Queen Camilla — as well as the then Prince Andrew, who has since been stripped of his royal titles. Producers say the series emphasises Diana’s agency and presents her account in her own voice rather than framing her solely as a victim.
Creative angle
Producers say the series restores Diana’s authorship
Love Monday TV’s Creative Director Kerene Barefield told Deadline the intent was to ‘challenge the narrative that has too often portrayed Diana, Princess of Wales simply as a victim of her circumstances.’ She said Diana Unheard aims to present ‘Diana not as a passive victim of events, but as a woman taking control of her own narrative and risking everything to make her voice heard.’
Sales pitch
Cineflix highlights rarity of hours-long intimate recordings
Richard Life, SVP Acquisitions and Co-productions at Cineflix Rights, told Deadline that the series offers ‘the unique opportunity to hear several hours of intimate recordings of the Princess; her own story in her own voice at a pivotal point in her life.’ He added that Diana remains ‘a global icon and source of endless fascination for viewers’ and that Cineflix is ‘thrilled to be representing this premium limited series’ at MIPCOM.
Context
Renewed interest in Diana comes amid other royal controversies
Deadline noted ongoing public interest in Diana and the royal family and placed the documentary’s market launch against recent rows involving the Palace and Diana’s brother, Earl Spencer, over his memoir Swan Song: Diana, My Sister. The article positions Diana Unheard as arriving into a climate of heightened attention on royal lives and histories.
