At some level, it is important for us to tell stories about heroes who are not from the conventional worlds of sports, films and politics. We must celebrate the heroes of modern India and those who've built our country. And this really gave us an opportunity to tell the story of Homi Bhabha and Vikram Sarabhai, who everyone might have read about in their history books, without knowing that there is so much more that we don't know about these great men who built so many great institutions in India that allow us to today be at par with the developed world. So, to start with, it was about telling the story of these two men. But obviously, the subliminal feeling was that it's important to tell the story of national heroes who have been unsung in the past.
