Ajay Devgan's upcoming movie 'Drishyam'

'The original film is so good that I haven't tampered much with it. I did not face any challenge as such while making the film. I am aware that there are people, who already now the story and have already watched it, but there is a large section, which has not seen it.' I would rather cater to them. And also there is a section who has watched the original and want to see how we have made it,' Kamat said. 'Drishyam', which also stars Shriya Saran, will release.
