He recently wrote a thought-provocative letter to his grand daughters—Navya Naveli and Aaradhya Bachchan—and starred in a video with the tag #AbSamjhautaNahi for UnBlushed! Amitabh Bachchan has taken a path-breaking steps to talk about women and their struggles before the release of his upcoming film Pink

Spilling the beans on how the idea bloomed in his mind, Amitabh said: "When we were promoting the film, a lot of people asked about the story and concept of ‘Pink’. We were getting a little hesitant on what we should say."

"That’s when Shoojit suggested me to write a summary of the film in a letter and send it to my granddaughters. It will be for all the girls," he added.

Instead of writing a letter to the girls, should there be a letter to the boys to tell them how to behave?

Answering in the affirmative, Big B said, "I think you are right. This should happen," and added, "I always feel that if we need to bring any change in the society, then we need to look after our children from childhood. We should tell them what is wrong and what is right. We all are equal."

Speaking his heart out, he added that he has never differentiated between his son Abhishek Bachchan and daughter Shweta Bachchan Nanda.

"I have always levelled things for my son and daughter. When I will die after living all that is left in me, I will divide all that I have among them," he professed.

While sharing his experience of shooting the film, the national award-winning star said that there were various moments on the set when he broke down.

"All of us had been through that experience while we were making this film. I am not shy to admit that even at 74, there were scenes that moved me," Amitabh said.

"There were moments when we all broke down. I myself got moved by a particular scene in the film and left the set because I just feel embarrassed to be crying in front of a lady," he added.

While the film puts the spotlight on girls, when Amitabh was asked about the woman he looks up to for inspiration, he told thestatesman.com: "First of all my mother (late Teji Bachchan). If you see any values in me, you need to credit my mother for it."

Apart from Big B, the Aniruddha Roy Chowdhury directorial also features Taapsee Pannu, Kirti Kulhari and Andrea Tariang, Angad Bedi and Piyush Mishra.
