Diana, the film about the late Princess of Wales starring Naomi Watts, has its premiere tonight in Leicester Square and producers and the star are reportedly all prepared for a backlash.
Naomi has already raised concerns after walking out of a radio interview with presenter Simon Mayo who tweeted: "A first for me and @wittertainment as Naomi Watts walked out of an interview! She seemed a tad uncomfortable with the questions. Shame."
Mayo declared himself "baffled" by the exit confirming that he didn't say anything remotely upsetting: "The honest answer is I have no idea [why she left]...[I] didn't express any opinion. So still baffled."
It's obvious that tensions are running high - and perhaps it's unsurprising given the film's controversial romantic storyline.
The film focuses on her two year romance with heart surgeon Hasnat Khan (played by Naveen Andrews) which ended shortly before her death with Dodi Fayed in 1997. The storyline suggests that her romance with Dodi was a rebound relationship from Hasnat, the man she used to call 'Mr Wonderful'. It is largely based on the 2001 book Diana: Her Last Love by Kate Snell.
Khan has already dismissed the film, saying: "It is based on gossip and Diana's friends talking about a relationship that they didn't know much about.
"This includes some of my relatives who didn't know much about it either. It is all based on hypotheses and gossip."
Director Oliver Hirschbiegel told Sky News: "The film is actually based on the accounts of several people and the inquest in which there were hundreds of pages discussing their relationship.
"It is not a documentary, but a dramatic interpretation. In a love story you have to create four or five dramatic scenes that make it work."
Ingrid Seward, editor of Majesty Magazine, said that she doesn't believe Prince Harry or William will definitely not be watching the film: "It would be incredibly hurtful.
"They met Hasnat - well, certainly Harry met Hasnat - and I feel that once again their mother's memory has been hijacked."
