How did TBL happen?
I did theatre in Delhi with Abhishek Sharma. In 2007, Abhishek said, I'm making a film. He played an Osama Bin Laden tape, saying, this is what I want you to do. I was shocked. But tempted.

How did you prepare to play Osama bin Laden?

Vikram Gaekwad was our brilliant makeup designer. Make-up took three hours daily. There were prosthetics and shading. I grew a moustache and lost nine kilos. I had a dietician and a trainer who made me run till I fell flat. It evolved. But people's reactions to me as Osama bin Laden made me uncomfortable. Especially when they said I scared them.

How did you prepare for Noora?
Noora was difficult. Osama bin Laden was known, Noora undefined. The film's associate dialogue writer, Mohammad Ahmad sahab, worked with me for weeks to get the dialect. Ali helped. I wore shalwar-kameez even to malls and parties. Sikander, the rooster, stayed with me. Abhishek had these ideas of method acting. So the rooster and I lived together. He crowed from four till 11 every morning. I couldn't sleep. It worked beautifully though. Initially, I didn't even know how to hold the rooster. Eventually, the rooster brooded on my lap for hours.

We have a love-hate relationship. We love Pakistan because we are almost the same. The hate comes from terror.
