Nikkhil Advani, Farhan Akhtar and all the actors have gone through unusual exercise.

Before the start of shoot, the entire team including the crew spent two nights stayed at the jail set. It was an exercise to understand how it feels to be in confined space.

Nikkhil Advani made this unusual suggestion to get the entire team before the jail sequence into the space of the film.

According to source they had a blast during the stay. They shared stories, had jamming session. A big hit was jail escape stories by the director who has done lot of research on jail.

Produced by Viacom18 Motion Pictures and Emmay Entertainment and Motion Pictures, the film is directed by Ranjit Tiwari.
