Sanjay Dutt's next Bollywood film is Kalank and it's a big deal in many ways.

For one thing, the film will reunite the actor with Madhuri Dixit on screen after 22 years. The actor admitted that he is "a little nervous" about this reunion after all this time.

But another surprise Dutt gave was the inspiration of this movie and that Kalank was originally a concept by late filmmaker Yash Johar.

Dutt revealed that he first heard the director mention the idea during their shoot for 1993's Gumrah.

"During the shoot of Gumrah, Yash uncle had briefly mentioned about the story. Dharma Productions is like family, so when Karan approached me with the film, I had to do it."

He added, "It is also a coincidence that my character is named Balraj, which is my father's [Sunil Dutt] real name. He too came from Pakistan during Partition, so it has an emotional connect."

Kalank, which also stars Alia Bhatt and Sonakshi Sinha, is slated for release on April 17.
