The life of the late Princess Diana has always generated a a great deal of interest and curiosity. Now 15 years after her death, Princess Diana's story is all set to be told again to the world. This time with a budget of £30 million, reports express.co.uk.

In the retelling the tale, it seems, 11 years of Diana's life will be included, starting from just after Prince Harry's birth, British film producer Stephen Evans told the Sunday Mirror.

Oscar-winning South African actress Charlize Theron, 36, and 26-year-old Carey Mulligan are being tipped as contenders for the lead role.

Evans, who has already seen success reproducing former Prime Minister Baroness Thatcher's life in the form of the movie The Iron Lady, is apparently basing the film on Diana's bodyguard Ken Wharfe's memoirs from his book Diana: Closely Guarded Secret, released in 2007, reports ibnlive.in.com.

Evans was further reported by Daily mail as saying that he wants the world to know the truth behind what happened to Diana before she split with her husband Prince Charles in 1996. The Princess, had she been alive, would have turned 51 this year.  

Speculations are that in the movie Diana's bodyguard Ken Wharfe could be played by Ewan McGregor, 40.

Wharfe used to look after Princes William and Harry when they were young and was called Uncle Ken by them.

According to Evans, The emphasis on this really is authenticity and to discover what she went through. The rocky relationship between Diana and Prince Charles has been extensively covered by the media, but even so, there are some facts that are still hidden from public knowledge.

Evans also said that once Diana made up her mind, she was like a bulldozer and that she was lethal.  She ­utilised friendships and dumped ­friendships, he added. 

He announced that the movie will not be touching upon Diana's relationship with Dodi Fayed or the car crash in which she lost her life. He has made it clear that in the movie, Diana is neither portrayed as a perfect woman, nor a pain in the neck. The movie takes a neutral stand and it is left to the audience to judge the character or come to conclusions about it.

This is not the only movie that is being made. Apparently, there are two other movies in which Scarlett Johansson and Jessica Chastain are reported to be portraying Diana.
