Sanjay Dutt's grand mother Jaddanbai plays an important role in his life. Jaddanbai is mother of vetren actress Nargis Dutt. Sanjay Dutt’s life, embattled and controversial, is unlike anything we have seen in a Rajkumar Hirani film before. Sanju, therefore, was not expected to be your usual Hirani film, full of colour and life. It was a dark subject, with various shades of grey, and that is how Hirani and Sanju’s Sanjay Dutt, Ranbir Kapoor, deal with it.
