A new movie, which reportedly depicts the late Princess Diana's two-year romance with heart surgeon Hasnat Khan, will likely become the latest biopic to have its accuracy challenged. According to Britain's Sky News one of the critics is Khan himself, who remarked, 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. The film, titled Diana, starring Naomi Watts and Naveen Andrews, is directed by Oliver Hirschbiegel, who told Britain's 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. The film is scheduled to premiere in London tonight (Thursday).
