Vardhan Puri said in an interview that his grandfather once gave him a key tip for life -- to always remember his roots. "My grandfather gave me this tip. He said many actors, who come from a theatre background to films tend to forget the theatre preparation. And they start behaving in a starry manner, start partying and acquire attitude. They walk around with an entourage. My grandfather told me not to get into all this."

"He said, 'Do these things only as part of the profession but do not let these things become a part of your core. Let your core be that of a theatre actor. Always behave in the way that you are at your roots, which is that of a theatre actor. If you do that, the chances of failure are less'. That is what my grandfather told me and that is my Bible," Vardhan told reporters at the film's trailer launch.

Shivaleeka Oberoi talking about the same said, "It's still surreal for me to be in front of the camera but it's definitely easier to understand the director's perspective because I have been on the other side. It opens up the mind and helps in understanding what the director wants from this shot or this scene."

Shivaleeka Oberoi believes that her experience as an assistant director has helped her immensely. She has previously worked as an assistant director on films Kick and Housefull 3.

According to Vardhan, getting into the skin of his character, Sahil Mehra, was a challenging task. Opening up about how challenging it was for him, Vardhan explains, "It is emotionally one of the most difficult yet satisfying phases of my life playing Sahil Mehra. It's like playing five different characters at the same time. Since the character is so layered and nuanced, there are so many emotions involved. Sahil reacts very quickly and is an extremist."

Vardhan Puri visited a mental hospital and the Central Jail as character prep. "We went to a hospital in Agra where they treat mentally ill patients and spent a lot of time interacting with them and the doctors. I've met some really complex minds and got really affected by that. If that wasn't enough, the same day we decided to visit the Central Jail and went to the High-Security Vault where some of the most dangerous criminals in the history of India stay."
