Rajkummar Rao is one of those versatile actors who believe in pushing the envelope whilst preparing for his character. Having worked together on three critically-acclaimed films including Shahid Citylights and Aligarh , Rajkummar and filmmaker Hansal Mehta are set to take their association to the next level by collaborating once again for Omerta , based on terrorist Ahmed Omar Saeed Sheikhs life. Taking his role preparation extremely seriously, Rajkummar actually asked his co-star to beat him up. He informed, There was a scene in which the police remand Omar and I was hung upside down. The action crew and actors were required to thrash me for the scene. So I asked them to actually beat me up. When asked the reason behind doing this, the actor said, Its important that the scene look authentic. I wanted to feel the pain because that makes Omar mentally strong. I wasnt scared, Rajkummar adds. For those who are unaware, Omar Sheikh, a British terrorist of Pakistani origin, is infamous for his role in the murder of Wall Street Journal reporter Daniel Pearl in 2002.
