/> Filmmaker Sanjay Gupta is going into the publishing.

"We'll be commissioning a book on the making of my next, autobiographical film Alibaug, and also the screenplays of my short-story features Dus Kahaniya."

But first, Gupta is paying his friend Sanjay Dutt the ultimate tribute. He's commissioned a 3-volume biography on the superstar to be written by journalist-author Neelesh Mishra.

Explaining the voluminous endeavour Gupta says, "I don't think Sanju's life can be encapsuled in one book. His life isn't only exceptionally eventful, but also very inspiring. We've decided to divide Sanju's story into three volumes.

The first volume takes us into the his story until he went into rehabiliation for drug cure. The second volume goes through his marriage with Richa Sharma, the divorce and her tragic death. In the final volume we'll go through Sanju's court procedure, probation and beyond."

Sanjay Dutt would be personally sitting with the writer over several sessions sharing his darkest fears and thoughts.

"This would be Sanju's no-holds-barred story," says Gupta.

Author Neelesh Mishra who's also a lyricst says, "Sanjay Dutt's life is an amazing story. It mirrors the sunshine and darkness of Bollywood itself. I see it as a very challenging international project, far more difficult than the three books I've written so far. Hope I do justice to it."
