After the superhit successes of three films, Sanjay Dutt is all set to collaborate with Rajkumar Hirani and Vidhu Vinod Chopra for the fourth and most special association, Dutt biopic.

The bond between actor Sanjay Dutt and filmmakers Rajkumar Hirani and Vidhu Vinod Chopra dates back to the trio's first film together Munnabhai MBBS in 2003. 15 years after the first film, the trio is all set to come together for the biggest association of the three-the biopic of Sanjay Dutt.

Though Sanjay Dutt won't directly be a part of the film, the actor regards the biopic as the biggest association with Rajkumar Hirani and Vidhu Vinod Chopra.

Talking about the special association Sanjay Dutt shared, "Vinod and Raju are like family to me. They have been an important part of my life. While we have worked together multiple times in the past, my involvement in our recent association has been very different".

It was the immense love that the three share that made the biopic possible. Rajkumar Hirani spent hours and hours watching over 300 hours of footage for the biopic, which is a testimony of their bond.

About the biopic Sanjay Dutt shared, "Usually, they narrate the story to me. This time it was me who kept narrating my life stories to them."

After the blockbuster success of Munnabhai MBBS, Lage Raho Munnabhai and PK, the trio will mark their fourth collaboration with the untitled Sanjay Dutt biopic. Sanjay Dutt, Rajkumar Hirani and Vidhu Vinod Chopra weaved magic on-screen each time the three collaborated. The trio could be considered a hit formula, as they have never gone wrong.

While PK starred Aamir Khan in the lead, Rajkumar Hirani and Vidhu Vinod Chopra made sure to make Sanjay Dutt a part of their venture.
