In an interview to PTI, Neil Nitin Mukesh said, "Wazir is nothing but dark, he mocks and enjoys somebody else's pain. This is my darkest portrayal yet. I myself was quite shocked that I played this character. He is very unpredictable... Whether it's his face, voice or look, I had to work extremely hard for this.''
Neil Nitin Mukesh further added, ''When the film was offered to me, at that time it was titled Ek Aur Ek Do... After I finished shooting, I got a call from Vidhu sir and he said 'What have you done?' I asked him if he was not happy with my performance. He said, 'Happy? I am changing the name of my film to Wazir now.'"'
Talking about Amitabh Bachchan, Neil said, "When I got to know that my character would be intimidating Bachchan sir's character, that was scary. His name is itself intimidating so getting on screen trying to intimidate him was not an easy task. But, that's where the acting kicks in. I did not want my nervousness to affect his performance so I made sure all the butterflies which were fluttering in the stomach, remained there and never came out on face.''
