Nani's physically gruelling adventure

Nani, who shot at the base camp of Mount Everest for his Telugu film 'Yevade Subramanyam', is yet to come out of the impact of the adventurous experience.

"It was the most physically gruelling adventure in my life," says the 'Naan Ee' and 'Aaha Kalyanam' actor, adding: "I can't forget the experience in my lifetime."

"My heart was in my mouth for a few times during the shoot at 5,300 metres above the sea level," he adds. The cast and crew of the movie shot there for 40 days, braving freezing climate.
