Directed by Anurag, it stars Abhishek Bachchan, Aditya Roy Kapur, Rajkummar Rao, Fatima Sana Shaikh, Sanya Malhotra and Pankaj Tripathi and is produced by Bhushan Kumar, Divya Khosla Kumar, Anurag, Tani Somarita Basu and Krishan Kumar.
Sanya had earlier told : "He (Anurag) is a genius and I have never been so chilled out during shooting. He doesn't like to work with a script, and that's what I am liking.
"Generally, when I am working... if I have script in hand, I go all crazy reading it all the time. I read the script after the shoot or before going on set. I go through it all the time. I feel that I might find something new in it," she added.
That way, working on the film is quite different for the "Dangal" actress.
"One thing you don't know is what he (Anurag) wants on the set or which scene you are going to shoot when you come to the set in the morning. He just tells us that we are shooting this and we have to say something like this," she said.
"You have to be on your toes and be spontaneous. It's like being a part of a play... doing something impromptu on stage. I am having a lot of fun," she added.
