Voted Black Swan.
Nathalie Portman deserves her oscar for best actress for sure. The emotional spectrum she presented is simply outstanding and the atmosphere of mental breakdown was flawless. But I feel that the award for best movie must be supported by main character, script, screen writting AND secondary characters. Vincent Cassel made a damn good job to create an extremely stressful and disturbing atmosphere but I think Mila Kunis's character didn't had enough chance to help this.
2nd would be Toy Story 3. The scene in the melting oven where they all hold hands and close their hands created a bubble of sadness that I never experienced since that scene in "Life is Beautiful" where Roberto Benigni is joyfully skipping to his death...
The humour was great, the story was great, colourful side characters, good soundtrack etc...
If King's Speech wins for best movie, I will be disgusted and furious but if Helena Bonham Carter wins for best supporting actress...
Look, she's a great actress but she gave for that movie doesn't deserve any kind of reward or praise.
a) When your playing a member of high social status or royalty, you need to keep of certain standard to comportment. Something I would call a "stiff" comportment expected by others members of the society you are part of. It's normal and expected and the actor's job will be to keep while allowing your emotions to pass trough it. And sadly, Queen Elizabeth royal "stiffness" was thick that no emotions what so ever pass trough. The whole movie she kept that appearance of mild annoyance and condesendence.
b) And to be a "supporting character" you need to "support" the main character as he struggle to vanquish adversity. She convinced her husband to go see Logue then monitored the process. Geoffrey Rush was the only supporting actor of this movie.
In my opinion, if you want to give her an oscar for supporting actress, give it to her for her great performance as Mrs.Lovett in Sweeney Todd. Hell, even as Bellatrix Lestrange in Harry Potter, she gave better performance.
