The Meghna Gulzar-directed film is inspired by the sensational murder of 14-year-old Aarushi Talwar and 45-year-old Hemraj Banjade, a domestic help in Noida, India in 2008.
It sees the 35-year-old actress play the role inspired by Nupur Talwar, Aarushi's mother, who has been convicted for her child's murder with husband Rajesh.
"I am happy with the response that the film has been getting. It is a very good feeling. I hope more people go and watch it," Konkona said on the sidelines of Amazon India Fashion Week.
"Talvar" also stars Neeraj Kabi and Irrfan, who play the role of Rajesh Talwar and CBI investigator Arun Kumar, respectively.
