Aamir Khan who didn't know swimming at all, has finally learned the sport for his upcoming suspense-drama film 'Talaash'. Apparently, it wasn't only regular swimming that he had to learn, but he was also trained for underwater swimming which is more difficult.

Aamir who plays inspector Shekhawat in the movie, will be seen doing a shot of an underwater sequence. This sequence required Aamir Khan to do the under water swimming that was shot extensively in London.

Undoubtedly, swimming is something that takes a lot of time and it requires hardcore practice and dedication towards leaning something completely new, but Aamir pulled it off with ease.

Director Reema Kagti who was present during Aamir Khan's training was quite impressed. "Aamir I really have to tell you, I'm very impressed with your swimming", she said, complimenting him for his dedication.

In fact the entire crew was surprised to see that Aamir had picked up the sport so soon.

Aamir Khan understood the basics from Mickey Mehta, but David helped him throughout the learning process. He says, "Actually Dave is helping me prepare for the under water sequence, he is helping me with breathing exercises which increases my lung power and allows me to stay under water for a longer period of time."
