"I knew for a fact that some day 'Ponniyin Selvan' would get made into a film. I knew either Mani Ratnam would make it or I would make it," Kamal said at the grand audio and trailer launch of the event that was held at the Jawaharlal Nehru Indoor stadium in the city on Tuesday. In fact, there was a competition between us as to who would make this epic novel into a film. While I made efforts, he continuously kept making efforts and has won. This is a big successful film. This will be a very important film in Mani Ratnam's victories list," Kamal said and went on to recall a time when they (Mani Ratnam and Kamal) used to lean on a motorcycle in his home in Alwarpet and talk wonder if they could ever make films like 'Sholay'.
