Rajkumar Hirani, who is currently shooting for his upcoming film, a biopic on Sanjay Dutt, is getting nostalgic with memories of shooting with Sanjay Dutt and Sunil Dutt for Munna Bhai M.B.B.S. Sunil Dutt played a very important part in Sanjay Dutt’s life and his character in the biopic would be very important. Fortunately, Rajkumar Hirani has had the chance to not only interact with Sunil Dutt but also shoot with him, so he knows him much better.
