Award-winning director Henry Singer, who also made The Betrayed Girls and 9/11: The Falling Man, turns his attention to the death of Diana in this new film.

It focuses on the astonishing week after her fatal accident and asks: what was it about Diana that caused an outpouring of public grief on such a scale? And how has Britain changed in the two decades since?

Contributors include Diana’s lady-in-waiting Anne Beckwith-Smith, and her brother Earl Spencer.
