Kamal Haasan’s Vishwaroopam has been a fascinating subject for fans. Selvaraghavan was originally supposed to direct the film but he had to leave the project as he was caught up in prior commitments and Kamal did not wish to delay the film any further. Sonakshi Sinha had been roped in for an important role but she also had to opt out because of date issues. Kamal is gung ho about this project, initial hiccups notwithstanding and it is a hugely awaited film which is supposed to be one of the biggest films ever.
