Rajkumar Hirani, who has just returned from the United States, had a long stay overseas with Abhijat Joshi. The duo was  busy penning the script encompassing the chequered life of Sanjay Dutt, who is currently serving a jail term in Yerawada prison.

After PK, Hirani moved to the biopic, his first in the genre.

Hirani and Sanjay have already worked together on successful social satirical dramas — Munnabhai MBBS,  and Lage Raho Munna Bhai. Now it is to be seen how convincingly the director brings Munna Bhai’s real story on the screen.

The director, who once said that the world knows only one-tenth of Sanjay’s life, is planning to show all the facets of his life, whether it is well-known or unheard of to the audiences. It has been heard that he wants to capture all aspects of Sanju&’s life.

Sources say that Hirani is looking forward to start shooting for the film at the earliest.

Sanjay, who was convicted for possession of arms in connection with the 1993 Mumbai serial blasts and serving a jail term, is expected to be out later this year.
