I reserve the right to change these up to the ceremony. :P
Best Picture
Slumdog Millionaire
It's got all the hype and many of the precursors. Barring some huge upset, it's got this in the bag. The Curious Case... will continue its trend of being nominated for tons of big things but winning none of those big things.
Alternate: Milk
I've seen/Should win, with my limited viewings in mind: Milk, The Curious Case... (yes, I watched it online a little while ago, and OMG SOOOO BORING and just... not right at all, tonally), and The Reader / Milk
Snubbed: Wall-E
Best Director
Danny Boyle, Slumdog Millionaire
See above.
Alternate: David Fincher
I've seen/Should win: Daldry, Fincher, Van Sant / Van Sant
Snubbed: Christopher Nolan, The Dark Knight
Best Actor
Mickey Rourke, The Wrestler
It's close with him and Sean Penn. But I think, in the end, the "underdog" story will truly appeal to the voters, those saps. ;) It will be CLOSE, though.
Alternate: Sean Penn
I've seen/Should win: Penn and Pitt / PENN.
Snubbed: Robert Downey Jr., Iron Man. Not kidding.
Best Actress
Kate Winslet, The Reader
KING OF KINGS! AND LORD OF LORDS!!!!
Alternate: Meryl Streep
I've seen/Should win: Hathaway, Leo, Streep, Winslet. Whoo, almost done! / Winslet
Snubbed: Rebecca Hall or Scarlett Johansson, Vicky Cristina Barcelona. I finally saw all of Happy-Go-Lucky, and Sally Hawkins does not deserve to be in this category, sorry.
Best Supporting Actor
Heath Ledger, The Dark Knight
The only real, true lock.
Alternate: Don't need one, but PSH
I've seen/Should win: ALL OF THEM YAAAAAY / Ledger
Snubbed: Bill Irwin, Rachel Getting Married and Brad Pitt, Burn After Reading
Best Supporting Actress
Penelope Cruz, Vicky Cristina Barcelona
Meh? Good, nomination-worthy, but not OMG GIVE HER AN OSCAR RTM-worthy at all. At least, if they give her an Oscar now, they can get it out of the way. And ha ha, she's not going to get her boyfriend to present it to her. I hope the inane little thing cries about it and not in a good way. Wow, I'm so mean! I can still see any of the nominees here upsetting; Pene's not a huge frontrunner.
Alternate: Viola Davis, Doubt
I've seen/Should win: Adams, Cruz, Davis, Henson / Davis
Snubbed: Rosemarie DeWitt, Rachel Getting Married (though I have her in lead)
Best Original Screenplay
Milk
The film will more than likely pick up its only major award here.
Alternate: Wall-E
I've seen / Should win: ALL OF THEM YAAAAAY / Wall-E
Snubbed: Vicky Cristina Barcelona
Best Adapted Screenplay
Slumdog Millionaire
Get used to "Jai Ho," people. You're going to hear it A LOT on Oscar night when those guys go up to get their 500000 trophies.
Alternate: The Reader
I've seen / Should win: The Curious Case..., Doubt, The Reader / out of those, um, The Reader I guess
Snubbed: Revolutionary Road
Those were my long predictions for the major categories... I'll have a full list up in a few days.
