Despite how private the British royal family keeps their personal lives, they've remained the subject of tabloid scrutiny and public interest for centuries. Queen Elizabeth II, Prince Philip, and more members of the family are certainly fascinating, but it's Princess Diana who truly captured the hearts of people all over the world. Both before and after her tragic, untimely death in an August 1997 car accident, the royal's life has remained in the spotlight and has subsequently been the subject of many documentaries to mark the 20 years since her passing.

4. Unlawful Killing 
Keith Allen's 2011 British documentary film about Princess Diana and Dodi Fayed's death, Unlawful Killing, faced mounting criticism after premiering at the 2011 Cannes Film Festival. The movie claims the British and French authorities covered up important details about their car crash, and asserts Prince Philip orchestrated their murder (it also calls Queen Elizabeth II and Princess Margaret "gangsters in tiaras").
The film — which was financed by Mohamed Al-Fayed (Dodi's father) — is full of other scandalous allegations about the royal family that led to it being banned from a theater release in the UK. Allen tried to distribute it in the US instead, but it was also withdrawn due to threats of possible litigation.

7. Diana: The Witnesses in the Tunnel 
Rather than taking a look at Princess Diana's life as a whole, this 2007 film offers an in-depth look at the night of her and Dodi Al-Fayed's car crash in the tunnel in Paris. Directed by Janice Sutherland and Stuart Tanner, it examines the final photographs taken of her by the paparazzi who were subsequently arrested that night and who actually witnessed the aftermath of the tragic event in person. It offers a sympathetic view of the photographers, and attempts to overturn the claim that they slowed down the ambulances trying to reach the princess.
