Oliver Hirschbiegel's Diana biopic looks destined to split opinion. Profiling the late Princess's final years and her relationship with heart surgeon Dr Hasnat Khan, the upcoming movie starring Naomi Watts is based largely on Kate Snell's 2001 book Diana: Her Last Love.
Now Khan, the unwitting subject of the film, has spoken out against the dramatisation of his relationship with the late royal, calling it "completely wrong".
"It is based on gossip and Diana's friends talking about a relationship that they didn't know much about, and some of my relatives who didn't know much about it either," he told The Mail on Sunday. "It is all based on hypotheses and gossip."
The cardiologist, who is portrayed by actor Naveen Andrews, revealed he had seen a still from the film which he said convinced him the relationship would be misrepresented. "I could tell immediately those were never our mannerisms at all, with [my] hands folded behind the back and all that.
"You could tell from that picture that it is all just presumed about how we would behave with each other, and they have got it completely wrong. There wasn't any hierarchy in our relationship. She wasn't a Princess and I wasn't a doctor. We were friends, and normal people stand like friends with each other. That one picture told me a lot about how they will portray things in the film and I can see [it] is wrong."
Khan also announced he would refrain from watching the biopic when it's released in UK cinemas on September 20. "A friend asked me the other day if I would sneak into a cinema to see the film. But there is no way I will watch it. There's no way I am going to go anywhere near it, not now or ever.
"Most of it is going to be based on gossip, and if I watched it I would be sitting there saying, 'That's wrong, that's wrong, that's not right,' every second. I couldn't put myself through that. It would be absolutely terrible."
