The life of the most beautiful woman had always been under the scanner, be it her social life or personal life. Getting married to Prince Williams made Diana a household celebrity overnight and her popularity was ever soaring. But, her untimely death in car crash in 1997 became the mystery which could never be unraveled.

With her closeness to her then bodyguard Ken Wharfe added fuel to the fire. So, producer Stephen Evans is all set to bring her life on the silver screen. And, he is lining up a Hollywood actress to play the late British royal.

Diana's film will be based on her bodyguard Ken Wharfe's memoirs from his book "Diana: Closely Guarded Secret".

"We are dealing with about 11 years of her life from just after she had Harry, when he's aged about two, and it's partly from the point of view of her protection bodyguard," contactmusic.com quoted Evans as saying.

"The emphasis on this really is authenticity and to discover what she went through. Unless you are a Diana freak, quite a lot of it will be unknown to the audience. The movie's not saying she is unbelievably wonderful or she's a pain in the neck, the audience can make their own view," he added.
