Script of Durga Rani Singh is ready, but Kahaani-2 only had idea not story. So Sujoy Ghosh with his team did some changes in Durga Rani and converted it into Kahaani. Both are thriller, so it must be not difficult to change. Shooting of Kahaani 2 has been started. According to the sources, When all the controversies got over between Vidya and Sujoy, then they talked on this film. Means there will be no project named with Durga Rani Singh.
