After Noami Watts, actress Emily Blunt is all set to play Princess Diana in Stephen Evans' Diana: Closely Guarded Secret.

As the first biopic Diana focuses on the last two years of the Princess' life, before she died in France in 1997, following a tragic car accident, the second biopic, in which Blunt will star, will be based on the memoirs of Diana's former bodyguard, Ken Wharfe.

Blunt says the experience of being transformed into the beautiful Princess was an extraordinary experience. She also says that, her role brought back memories of being a schoolgirl and hearing of Diana’s death, in 1997.
