Hirani afterall not that a honest man to reveal all secrets of Dutt especially the reason to his connection with underworld and the arms he kept. Hirani is going to present him as an innocent boy so that all sympathies goes to Dutt that he was victim of the system etc. Only then the movie will be a hit because people always have sympathised with Sanjay because of his bollywood connection. Hope his biopic also comes out as a book so that it sells like hot cakes and Sanjay gets royalty.
