Taapsee essays Prakashi while Bhumi Pednekar plays Chandro.
During a month-long filming schedule in Meerut, Taapsee stayed at Chandro's house. She would have lunch at Prakashi's house and dinner at Chandro's place.
"It was the best experience I have ever had. Living in Johri and spending time with these two ladies, who have strength and compassion, was inspiring," the actress said, adding: "There were so many stories to hear from them and so much to learn."
The Reliance Entertainment film will mark Bollywood scriptwriter Tushar Hiranandani's debut as a director. It is jointly produced by Anurag Kashyap and Nidhi Parmar and is slated to release around Diwali this year.
