Vishwaroopam after a spate of controversies, managed to release in 2013. The film had to face many roadblocks and Kamal Haasan in fact told media that if creativity was to be gagged like this, he would consider moving out of the country which led to a lot of trolls.
After the release of the film, Kamal announced that he had also readied major portions of Vishwaroopam 2 and that also would be released soon. But four years since, no trace of the film.
That's when Ulaganayagan took to his social media space to say, "4 all looking forward to VR2. Am personally getting in 2 clear the path. Bigger obstacles are out of the way. Whats left is technical & legal. But bear with my team and me. Post will take 6months". This clearly means that we won't get to see Vishwaroopam 2 in 2017.
