As Naomi Watts films a biopic of Diana's life, another film about the princess has been scrapped.
The Keith Allen directed documentary Unlawful Killing, that claims that Diana was murdered in a plot involving her father-in-law Prince Philip, will not be released after producers failed to secure insurance to protect distributors against legal action.
Lawyers had warned there are 87 contentious allegations that would have to be cut before a British screening and although there were plans to release it in the US in August to coincide with the 15th anniversary of the deaths, the insurance was needed to protect the European offices of the distributors.
A spokesman for the movie - which was screened at both the Cannes Film Festival in France and the Galway Film Festival in Ireland in 2011 - said: "'Unlawful Killing' has been sold all around the world.
"But there was a specific form of insurance needed by the US distributors to cover them for their French and UK offices.
"This proved impossible to secure. The film has been withdrawn in perpetuity."
The £2.5 million film had been bankrolled by Dodi's father Mohamed Al Fayed, who has always claimed the deaths were not an accident.
Meanwhile, Naomi Watts is currently filming Caught In Flight, which sees her portray the late princess in the final few years of her life.
