When Prince Harry and Meghan Markle announced their Netflix deal, speculation ran rampant on what shows the couple would produce. By far the most common of these rumors focused on some sort of documentary about Princess Diana. Markle is often put at odds with Princess Diana in the tabloids, so this theoretical documentary is usually framed as a direct slight against the royal family. Gossip Cop has collected these rumors here.
In the National Enquirer version of the story, Prince Harry signed the Netflix deal as a way "to create a definitive work to honor" his mother. While the tabloid couldn't say whether it was a documentary or a drama, it said the potential film would serve a dual purpose: It'd be a way to pay "tribute to his beloved mother" while also playing a part in his feud with Prince William, with whom the duke "has a score to settle."
In reality, however, Prince Harry worked directly with his brother on the documentary Diana, Our Mother: Her Life and Legacy. He would have no need to sign this deal for the sake of creating something he already made, and so Gossip Cop concluded this was bogus.
Conspiracy theories about Princess Diana's death exist in abundance and infamy. Prince Harry has never disputed the official story of his mother's tragic death, which made the Star story about a revenge documentary all the less believable. The tabloid said making a documentary against his families wishes would be "a great opportunity for Harry to control the narrative.”
Apparently, he "holds a grudge against the Queen and Charles for not doing enough." This article came out right around the anniversary of Princess Diana's death and tried to capitalize on questions regarding the duke and duchess' finances, which the tabloid said was a primary motivator for a documentary. The couple does not need to exploit Princess Diana like Star is doing to earn money.
Prince William was "rocked," according to New Idea, when he learned about the Netflix contract. He was reportedly mortified because "Meghan often said she'd love to do a documentary about Princess Diana's life." There was "not a lot [Prince William] can do to stop the Sussexes making a documentary about Diana," but he was still going to "injunct them at every turn."
As this story exemplifies, Meghan Markle is typically the source of conflict as Prince William was flabbergasted his brother would stand idly by and allow her to make the vanity project. Prince Harry and Prince William recently released a joint statement for the anniversary announcing a statue of their mother, so they are in lockstep on how to honor their mother's legacy — and that doesn't include an inflammatory documentary.
