Ahead of the anniversary of her death on Aug. 31, a new docuseries has been announced that will examine the 1997 Paris car accident that ended Princess Diana’s life at just 36 years old.

The series, called Who Killed Diana?, will explore the circumstances surrounding the death of the Princess of Wales 27 years ago. It will feature rare and, in some cases, first-ever interviews with several key sources, Deadline reported, and will aim to cast new light on the case that captured the world’s attention in 1997 — and has kept it for nearly three decades.

Who Killed Diana? will mark the first series in a broader franchise that will examine “the shocking deaths of iconic figures, hoping to uncover new information about the circumstances,” Deadline reported. The franchise will also examine “the human stories and historical context at the center of these cases,” the outlet continued.

The team behind Who Killed Diana? was also behind Netflix’s 2023 release Who Killed Jill Dando?, as well as fellow Netflix offerings like Depp vs. Heard and The Mystery of Marilyn Monroe.

“This new franchise will not merely revisit deaths of famous figures, it will actively drive the story forward with new voices and fresh insight into compelling and complex details,” said Jon Adler, head of talent and content development at EverWonder which, along with Empress Films, is bringing the series to life.

The late Princess Diana died alongside two others, Dodi Al Fayed and driver Henri Paul, in the accident in the French capital city. “There are very few moments like those in history,” royal biographer Ingrid Seward, who knew the royal personally, previously told PEOPLE. “I remember where I was in every tiny detail when I heard about Diana. It affected everybody.”

While no release date has been shared yet, Who Killed Diana? will be a three-part docuseries.
