Prince Harry is exploring the possibility of making a new documentary about his mother, Diana, Princess of Wales, as preparations begin to mark the 30th anniversary of her death in August 2027. The proposed project has quickly become one of the most closely watched developments surrounding the Duke of Sussex, but there is an important distinction between what has been reported and what has actually been confirmed.

However, the buzz around the alleged new project has led many to wonder if there already exists a Princess Diana documentary that features Prince Harry.

There is indeed a documentary on Princess Diana that features Prince Harry and also Prince William. In fact, this speculative new venture inevitably invites comparisons back to Diana, Our Mother: Her Life and Legacy, the landmark 2017 film that famously united Prince Harry and Prince William in sharing deeply personal memories and rare family archives to mark two decades since her passing. 

However, while that milestone project, which is currently available to stream on HBO Max, HBO Max Amazon Channel, Google Play Movies, and YouTube, was defined by a joint sibling tribute marking the 20th anniversary of their mother, any potential 2027 retrospective is shaping up to be an entirely different chapter, unfolding against a vastly changed landscape as the milestone 30th anniversary approaches.

That landmark 2017 project resonated deeply because it portrayed Princess Diana through the intimate lens of motherhood rather than solely as a global icon, with Prince Harry noting in the opening moments that it marked the first time he and his brother had spoken publicly about her in that specific light.

Critics even praised the documentary for its personal approach to the iconic royal figure.

Reviewing Diana, Our Mother: Her Life and Legacy for The New Yorker, writer Rebecca Mead characterized the documentary as deliberately restrained, praising the brothers' unusually personal reflections while highlighting the tightly managed nature of the production. Her critique underscored a fundamental challenge inherent in any project centered on the late princess: while audiences crave raw, unfiltered insight, those closest to her must navigate strict boundaries regarding what they choose to share.

Echoing that sentiment, Irish Times critic Fionola Meredith praised the feature as an emotive tribute while noting that a true sense of personal intimacy with Princess Diana remained just out of reach. These critical dynamics take on added weight as any potential 2027 retrospective led by Prince Harry would inevitably be measured against the benchmarks set by its predecessor.
