Nana will be essaying a role of a CBI officer in the film. Apparently, while shooting in Punjab Nana had some scenes in which he had to carry out some investigation work while interacting with people.
For the same, we hear that, Nana went up to three women with his dialogue script and requested them to teach him how to deliver his hindi dialogues in a typical Punjabi accent.
Director Sangeet Sivan was very impressed with Nana's dedication that he couldn't deny Nana's request and allowed the actor to deliver his dialogues in Punjabi.
Well, what can we say...Nana, Twada Jawaab Nahi!!
