Nawazuddin plays a lead for the first time in the film. The actor, who had long been overlooked, has become a name to reckon with after his performances in the critically acclaimed Kahaani, Paan Singh Tomar and Gangs of Wasseypur.
Suparn Verma, who called him a brilliant actor, said: "When we met, we had a very interesting and emotional meeting where he just fell in love with the film. He was on board. Bipasha Basu is also very excited to have him as part of the film."
"It will be a very interesting role that Nawaz will be playing," Verma told IANS.
Verma, who has directed movies like Ek Khiladi Ek Hasina and Acid Factory, refused to share the details of Nawaz's character, saying it was a secret. He just said that the actor will go into a hitherto untapped "emotional zone".
The director will be conducting solo workshops with Nawazuddin Siddiqui to prepare him for the part.
"We will be spending a lot of time with each other. We will also be doing workshops, just me and him (Nawaz) locked up. It a very intense character. It involves shedding a lot of inhibitions, emotions and exposing yourself completely. It is more about tapping into the character's emotions," he said.
Based in Mumbai, the film will also be shot in Panchgani.
The release date will be announced shortly. Sharing the plans, Verma said: "Most likely we will shoot on 17th and 18th of this month and then we will shoot non-stop till the end of August."
