When you watch Danny Boyle\'s latest rags-to-riches fairy tale \"Slumdog Millionaire\", you\'ll experience an emotional roller-coaster ride that only Mumbai can offer.  The city that never sleeps, the city that is in the center of the center of the world (as mentioned by Salim in the movie), a city that has an economic and social contrast ratio of 20,000,000:1, reveals itself on the screen as Danny Boyle and his screen writer Simon Beaufoy (based on the novel Q&A by Vikas Swarup) masterfully crafts the film using the television game show \"Kaun Banega Crorepati?\" or \"Who wants to be a Millionaire?\" as the spine of the story.
