Nandana Sen is working in both Hollywood and Bollywood films. 'Black' is her latest release. She has two Hollywood films in her hands. When we asked what is the technical different between this two industries, she replied, "I think technically we are as good as any other film industry in the world. Talent wise we are absolutely world class, not only in terms of cinematography and music, but, for sure as far as acting in concerned. But of course, there are different rules everywhere and the same industry will work differently in different parts of the world. I am still figuring out the etiquette in Bombay, as well s the rules in Hollywood. I'm learning as I go."
