Diana documentary shown at Cannes
Keith Allen has insisted his documentary about the death of Princess Diana is not "a sensationalist film".
The work, called Unlawful Killing, was shown to invited journalists at the Cannes Film Festival on Friday.
Keith told a press conference: "I didn't want to make a sensationalist film, I don't believe it is a sensationalist film. I think it is a very forensic analysis of a process, a British legal process, and I think it reveals things that, I'm sorry, don't add up."
The comic, whose daughter is pop star Lily Allen, said he had tried to get funding for the film from Channel 4, Channel 5, Sky and the BBC but had been turned down by them all. He then approached Mohamed Al Fayed, whose son, Dodi, also died in the 1997 Paris crash that killed Diana.
A spokesman for Mr Al Fayed confirmed that the former Harrods boss had provided around £2.5 million to fund the documentary.
The film, which is not entered into any of the official selections at this year's festival, features contributions from the late Tony Curtis, Lauren Booth, George Galloway and Mr Al Fayed.
Keith said he did not mention Mr Al Fayed's involvement during the film because it "would have interrupted the flow".
He added: "I think you'll find there are an immense number of films coming out in America and all over the world that are financed by the mafia and there is no reference to that."
The comic and actor said the film made reference to Nazi connections of the Duke of Edinburgh's family "as background information" and defended the brief use of a photograph which showed Diana in the car after the crash which he said was not "as sensational or revealing as people make it out to be".
