Bollywood is one of the most successful industry in India. The more profit  it does it produces it brings more employment and more money to the people who are involved in the industry ..Right from the Stars( who are over paid i agree, but thats just the beast of the nature) to the spot boys to the movie theatre owners and to the street vendor who sells peanuts outside the theatre. So Whatever it takes to make the movie successful financially is being done may that be shooting songs in geneva or Melbourne, if it's working then they are doing it right......And thats how it is done ....Capitalism at its best...
