Mockingly called Bollywood by locals and cynics, Film City clings to the outskirts of the National Park, and is practically overrun by assorted stars and starlets -- the demi gods and goddesses of Modern India. Don't snigger. Bollywood churns out over 900 films every year, all packed with those mandatory elements of song, dance, melodrama, violence and erotica that Indian audiences love. Which is probably why Film City sets are heavily booked around the year. They are closed to visitors, but special permissions can always be "obtained" to check out the action.
