Brave, Patrick Doyle
Beasts of the Southern Wild, Benh Zeitlin and Dan Romer
I was not a fan of this movie but I did like the pluck-heavy score, also by the director.
John Carter, Michael Giacchino
Looper, Nathan Johnson
Director Rian Johnson's brother Nathan creates another perfect score for one of Rian's excellent films. I think this is not quite as impressive as the work he did for Brick and for The Brother's Bloom, but it is still easily one of the year's best.
Cloud Atlas, Reinhold Heil and Johnny Klimek
By the way, here are the five scores that will most likely get nominated for the real awards:
Beasts of the Southern Wild
Life of Pi
Zero Dark Thirty
Take it to the bank.
