The last thing the world needs, you might think, is another Princess Diana documentary.
It’s a fair thought considering that almost 25 years after her death, her life and impact is still media fodder. Whether it’s a magazine cover or a book claiming to have new revelations or just an image of Kristen Stewart in a re-creation of her wedding dress for the movie “Spencer” or Elizabeth Debicki sporting the “revenge dress” for the series “The Crown,” the culture continues to have an insatiable appetite for all things Diana.
