Recently megastar Amitabh Bachchan said that one of the biggest changes in Indian film industry is the equal presence of women on sets in every department including production.

At the launch of book "Once Upon A Time In India - A Century Of Indian Cinema", written by film critic-cum-author Bhawana Somaaya, Amitabh, asked by her about the changes that he observed in film industry, quipped: "During my time, there would be two women on set, the heroine and her mother."

The situation has now changed, he noted.

"But now, 50 percent of the work force on a film set is female. I think that is a huge change. When young girls handle the film set whether it is production, camera, continuity department etc. you are just free as an artist to focus on your performance. Earlier, we used to handle our continuity. I like the fact how women are involved in the process of filmmaking. I hope more to come as director, writer and more that we have got in last few years."

During the interactive session with Somaaya, Amitabh also shared his childhood memories of watching films back in Allahabad and how it has changed over decades. "I was so excited to enter the first ever air-conditioned theatre in our Allahabad city!" he recalled.

Actresses like Mita Vashisht, Pooja Bedi, and Divya Dutta among others were also present at the launch event at The Club. The 232-page book is filled with history, illustrations, posters, and dialogues of various phases of Indian cinema.
