BEST SUPPORTING ACTOR

These five are  most likely to get the nomination:

Christian Bale-THE FIGHTER
Geoffrey Rush-THE KINGS SPEECH
Mark Ruffalo-THE KIDS ARE ALL RIGHT
Andrew Garfield-THE SOCIAL NETWORK
Jeremy Renner-THE TOWN

Matt Damon or Armie Hammer are possible, but not likely as of now.

My Prediction
Christian Bale-THE FIGHTER

My Personal Favorite
Christian Bale-THE FIGHTER
