Rao, who had teamed up with Hansal Mehta for 'Shahid', 'Citylights' and 'Aligarh', will play a radicalised Britisher of Pakistani origin Omar Sheikh (infamous for killing Wall Street Journal reporter Daniel Pearl) in Mehta's upcoming film 'Omerta'. In an interview to a leading daily, Mehta said, "This film is based on the said international fugitive, who was involved in Pearl's murder, and it covers a host of terrorist activities (including 26/11) seen through the eyes of this person, who was at the centre of it all. After watching 'A Mighty Heart' (2007), I wanted to know more about the predator and his reasons for choosing this path. While various films have tried to highlight terrorism or its repercussions, I felt it was important to explore the other side of the spectrum - what goes on in the minds of these terrorists. There are so many stereotypes associated with terrorism, but the truth is far more murky and cold. Omar came from a privileged background before eventually being radicalised. Actor Mukul Dev told me this story way back in 2005. I wanted to make this film before Shahid, but a lot of research was required and we kept revising the script."
As to why he roped in Rao for this role, Mehta said, "It was interesting to see him play a character that is totally diverse from what he did in 'Shahid'. Also, he surrenders himself to the role without any kind of baggage."
On his part, Rao said, "It's a complete contrast to what I did in 'Shahid'. I play the anti-hero here. I've tried my best to make this character as real as possible. I even stayed in London for a while to get the hang of his way of life. The character is extremely cold and aloof and it was a challenge to convince myself as an actor to believe in his convictions."

Ltd. and based on a story by actor Mukul Dev.
