"I'll take up this project only if all the necessary permission and approvals are obtained. There is no point in doing a film on a real-life figure unless the family is with you," said Sohail, who is currently busy helming "Mental", which features his superstar brother Salman Khan in the lead role.
Initially, her adventurous life as an action star was reportedly to be filmed by Vishal Bhardwaj, who had even zeroed in on a German actress Franka Potente to play the role.
But then Nadia's family put its collective feet down. Nothing was heard of the project thereafter.

Shedding light on the project, Sohail said: "A producer-friend of mine from Australia approached me with this project a couple of months ago. She's still doing the basic research. And for now I'm totally tied up with my underproduction film. So let's see."
While it's too early to talk about the casting, one can safely reveal that the role of the fearless phenomenon won't be essayed by a non-Indian actress.
