Telugu and Tamil cinema actress Pooja Hegde was signed as the female lead, and makes her Hindi film debut with "Mohenjo Daro". "While scripting the film, I was thinking that I needed someone with innocence and someone who did not have stardom baggage be received by the audience only as this character. I thus began looking for a fresh face when Sunita (Gowariker) spotted Pooja in a commercial and suggested that we call her. She called Pooja and I auditioned her. And that was it!"
