Book v/s movie

Every time a movie based on a book is released, I go in for the book first followed by movie, unless of course it has a fantasy story. Then in that case, the order is reversed. However, today I have a little fray going on in my head because of the movie Slumdog Millionaire based on the book Q & A by Arun Swarup. Slumdog Millionaire has made it to the headlines of today's newspaper, by getting 10 nominations at the Oscars, which supports the review I'd gotten from my friends. The thing which goes against the book is that it's by an Indian author, and frankly speaking, I have neither read not heard of an exceptional book written by an Indian author. I wonder what I should do first, read the book, or watch the movie. Speaking of movies based on books, the other day I watched this movie called Into the wild (I know, it's an old movie but I just watched it... big deal!), which was a strange movie. Strange I say, cause it wasn't that I liked the movie, but I didn't dislike it either, still if asked, I'd say it is a must-see kind of a movie. Though I wish I'd know the movie was based on a book, which was in fact inspired by a true story, then I'd have read the book first. I guess this true story bit was the one that makes it a must-watch. It's also got an awesome soundtrack (which I'm listening to right now) which is the debut solo album of Eddie Vedder, the Pearl Jam guy. Speaking of music, Mettalica's Death Magnetic is driving me crazy. I can neither get the songs out of my head, nor stop listening to them. I inevitably end up purging my playlist of all other songs. Woooha... I'm getting late... Gotta go.
