Pinto tells Britain's Sunday Times Magazine, "People in the city recognize me as the girl from 'Slumdog Millionaire,' and inevitably they stare. But when I visited the slums with an NGO, nobody recognized me at all. I didn't mind. As for Dev, they hounded him, calling him 'crorepati,' which means millionaire."
