Is Kamal's Vishwaroopam Copied from Aamir's Fanaa?

The first bunch of ‘Vishwaroopam’ stills out into media circles today show kamal hasan in look alike get up of Aamir Khan. The hair style, costumes and turban around the neck clearly indicate that Kamal took reference of Aamir, who played the terrorist role in ‘Fanaa.’ Perhaps, ‘Vishwaroopam’ is also heard to be a film with terrorist backdrop where in Kamal is playing even a character of terrorist. Then, that’s a good clone indeed.
