Will Win - Ludovic Bource "The Artist"
Could Win - Howard Shore "Hugo"
Should Win - John Williams "War Horse"
Commentary - This one is probably the least mysterious of the bunch, although with heavyweights like John Williams and Howard Shore you can't count anything out. In my opinion, John Williams delived his most inventive score in years in War Horse, and his Tintin nod proves he is beloved in the Academy. But when a film has no dialogue, then its score must carry the emotion of the story. In the case of The Artist, the score was the story. So while there are plenty of options, I honestly don't see any other film taking the prize.
