Royal commentator Samara Gill, however, expressed concern that Harry and Meghan would shift the focus onto themselves.
“Diana’s story is a very sensitive and coveted story to tell, and I think Harry and Meghan will absolutely butcher it with their own lens,” she said. “I really think it could be a potential disaster because they will tell their side.”
Gill also warned that such a documentary could permanently damage the already fragile bond between Harry and William.
“This will probably be the final nail in the coffin for William,” she added. “Diana’s story has been paraded out, used, and abused, and then for your own son to capitalise on that with his craven wife — that’s the pinnacle for me.”

Diana’s Legacy and Harry’s Reflections
The timing may prove significant, as the 30th anniversary of Diana’s death approaches. She died in a car crash in Paris in 1997 when Harry was just 12.
Over the years, Harry has frequently spoken about his mother’s influence and the trauma of her loss. In his memoir, Spare, he described walking behind her coffin and recalled how his father broke the news of her death. He also revealed he once consulted a medium who told him: “Your mother is with you.”
According to Harry, the psychic added: “Your mother says, ‘You’re living the life she couldn’t. You’re living the life she wanted for you.’”
Harry and William have also marked their mother’s legacy together in the past, attending the Concert for Diana in 2007 and visiting floral tributes left outside Kensington Palace for the 20th anniversary in 2017.
