Oscar winner Helen Mirren may be nearing 70, but her body doesn't look it! The actress is in such remarkable shape, that her body double hired for the upcoming war thriller, Eye in the Sky, is 39 years her junior!

Stunt performer Fleur van Eeden, 30, couldn't help but praise the English beauty's appearance in a recent interview. "No way does she look her age — she looks amazing," she said of Helen. "I want to look like that when I'm 69."

Set to hit theaters in 2015, Helen and Fleur have been filming the action-heavy drama in Cape Town, South Africa. “She is an amazing lady and thanked me so much for doubling her," Fleur gushed of the RED star. "She was awestruck by the beauty of where we were filming.”

Helen "twerks" after being honored with Harvard's Hasty Pudding Woman of the Year Award

Dame Helen first wowed fans in 2008 with her impressive physique when she was photographed rocking a red bikini on a beach in Italy. In 2011, she won the title Body of the Year in a poll by gym chain LA Fitness. But the acting veteran credits wearing the right footwear for her slim figure.

“Four-inch platform heels give you great height and make your legs look unbelievably long. I used to get them in stripper shops but now you can buy them everywhere. Unfortunately, that means everyone else had discovered the trick too," she previously teased.

“I also hold my tummy in," she adds. "It comes from being on stage." It looks like we'll need to pay a visit to the Helen Mirren School of Posture!
