Directed by Tigmanshu Dhulia, the film is based on the Red Fort trials of 1945.
"Tigmanshu is an amazing director. I think it is one of the most powerful scripts I've read after 'Rang De Basanti'. It is the fastest I've said yes to a film. I read the script and called in five seconds, hoping he doesn't change his mind," Kunal told reporters here last night.
The actor said it has been an amazing year for him so far, playing characters in different era, making him feel he is "time travelling".
The 39-year-old actor walked the ramp at the Van Heusen GQ Fashion Nights, looking dapper in a blazer.
Kunal said he always enjoyed walking the ramp and when it comes to style, his icon is Sanjay Dutt.
"It was a great show. I always enjoy on the ramp... For me the man who epitomises style in the country is Sanjay Dutt. For me he is the true blue rockstar. He is the ultimate style icon," the actor said.
