My personal picks (in the main categories)...
BEST PICTURE: "Up" (although they'll never give it to an animated film, so if I have to pick a live-action film: "Inglorious Basterds"
ACTOR: Jeremy Renner ("The Hurt Locker")
ACTRESS: Gabourney Sidibe ("Precious")
SUPPORTING ACTOR: Christopher Waltz ("Inglorious Basterds")
SUPPORTING ACTRESS: Monique ("Precious")
DIRECTOR: I'm torn between James Cameron, who did an amazing job and deserves some kind of recognition, and Quentin Tarantinio, because I like "Inglorious Basterds" better than "Avatar." I think. It depends on my mood. But right now, I'm gonna go with Quentin Tarantino.
SCREENPLAY: Bob Peterson & Pete Doctor ("Up")
ADAPTED SCREENPLAY: Neill Blomkamp & Terri Tatchell ("District 9") (Although I think this will probably go to "Precious"... which bums me out a bit. While I loved the performances in that movie, and it had some amazing moments, I actually thought a lot of it was slow and boring...)
