Dame Helen Mirren's body double for her new film is 39 years her junior.

The 69-year-old actress is in such good shape that bosses on the set of war thriller 'Eye in the Sky' have drafted in stunt performer Fleur van Eeden, 30, as her stand in.

Fleur - who is currently in Cape Town, South Africa, where the film is being shot - told the Daily Mirror newspaper: ''It's amazing to be playing her body double when I'm [almost] 40 years younger than her. But Helen looks fantastic.

''No way does she look her age - she looks amazing. I want to look like that when I'm 69.''

Fleur - who has also been a body double for the likes of 39-year-old Charlize Thero - has enjoyed meeting the Oscar-winning actress while they have been filming in South Africa.

The body double said: ''She is an amazing lady and thanked me so much for doubling her. She was awestruck by the beauty of where we were filming.''

One scene from 'Eye in the Sky' in which Fleur was asked to stand in for Dame Helen sees her race a 4x4 across rough terrain.
