Bollywood movies are in Hindi, which is the main national language of India. Most people speak it to a degree, although maybe not that well in places like Tamil Nadu, which has a big political movement against Hindi, which is seen there as a Northern imposition.   Most people in cities speak some English, but not everyone is fluent. Still, it looks cool to speak English, so a lot of Bollywood movies include English phrases like "Better luck next time" and "Rock and roll, man!"     Since it's in the nature of escapist entertainment to be fascinated with the rich, a lot of Bollywood movies, especially these days, are about Indians who have struck it rich in England or America. A lot of the time, they come back and realize that they need India, and girls wearing skanky Western clothes often put on a sari or a salwar-kameez and show their true nature as good Indian daughters.     Many Indians relate better to their screen favourites than to the people around.   Stars and superstars, hits and failures, outright commercial films and the art genre of films all are woven together in the Indian mind as entertainment supreme.   Let there be no doubt, we love our film industry and are justly proud of it.   Step out in India, the chaiwallah (roadside teamaker) is as knowledgeable (and voluble) as the most ardent film buff and there's no guarantee of who gets to close the discussion!
