Kate Winslet, 'The Reader' most definitley.She came back into the acting spotlight, and she totally took the entire industry by storm. If she doesn't win then:Angelina Jolie, 'Changeling'orMeryl Streep, 'Doubt'I haven't seen 'Frozen River' and I can't stand Anne Hathaway. But seriously, Kate Winslet for sure!And she should win best supporting actress for Revolutionary Road as well.
Should win is Melissa Leo, but I doubt that enough people have seen Frozen River and it came out so long ago. Probably the winner will be Kate Winslet.
