I''m predicting Slumdog will win 2 - maybe 3 Oscars - one of them being the brilliant screenplay.
The other 2 may be Best Director for Danny Boyle (but why the Indian director Loveleen isn't eligible for nomination is beyond me. Aren't the best scenes in India???)
And maybe "Jai Ho" for Best Original Song.
The past few years the Academy have awarded non-traditional songs in this category including some in a foreign language like Motorcycle Diaries, Once, 8 Mile, Inconvenient Truth, Hustle and Flow.
