British actor Keith Allen, the father of singer Lily Allen, directed the documentary Unlawful Killing, which charts the 2008 inquest into the tragic royal's death in a car crash in Paris, France in 1997.
It caused outrage in the U.K. over its use of a graphic photo of Diana moments after the crash, and was slated by critics when it was unveiled at the 2011 Cannes Film Festival - and now it's emerged the film will not get a general release.
A spokesman for the producers tells Britain's Daily Mail newspaper, "Unlawful Killing had been sold all around the world, including the U.S. But there was a specific form of insurance needed by the U.S. distributors to cover them for their U.K. and French offices. This proved impossible to secure. As a result of this the film has been withdrawn in perpetuity."
