"Nobody knows anything." Screenwriter William Goldman immortalized that phrase a few decades ago, and it's as true this Oscar season as it's always been. Perhaps even more so — not only are many Oscar races still wide-open, but the status of the ceremony itself is up in the air. But for now the show is still happening, which means the nominations are set to be announced tomorrow morning. Here are my hasty, shot-in-the-dark predictions in the top six categories:

Best Picture:
The Diving Bell and the Butterfly
Into the Wild
Juno
Michael Clayton
No Country for Old Men

I think we can all agree that No Country is in, right? Beyond that, it's something of a crap shoot. Michael Clayton is the kind of classy star vehicle the Academy usually responds to, and audience favorite Juno has become too big a word of mouth phenomenon to ignore. At one point, Atonement was looking like a front-runner for the win, but its Oscar buzz has subsided. On the other side of the coin, There Will Be Blood may be too bleak for the voters to embrace — it would have a better chance were it the year's undisputed critical champ, but with No Country in the mix, PTA's masterpiece could be shut out here. Instead, I'm predicting The Diving Bell and the Butterfly, an acclaimed true-life story that's only gaining momentum, and Into the Wild, the year's most Oscar-baity film directed by a respected actor, which is something that tends to go over well with the actor-filled Academy membership.

Best Actor:
George Clooney, Michael Clayton
Daniel Day-Lewis, There Will Be Blood
Johnny Depp, Sweeney Todd
Emile Hirsch, Into the Wild
Viggo Mortensen, Eastern Promises

Even if the Academy decides to overlook There Will Be Blood, they won't be able to deny the awesomeness of Day-Lewis' blazing performance as Plainview. Likewise, Clooney and Depp have recently become Academy favorites, and I dare say that had Sweeney Todd done more business Depp would've been the one to beat here. Hirsch is a bit iffier here given his age, but he carries Into the Wild on his capable shoulders, and if the film gets nominated I'm guessing he will be too. With the recent groundswell for The Diving Bell and the Butterfly, I think Matthieu Amalric should be seen as a contender here, although not nearly as much as if he was an American star. Instead, I'm going with Mortensen — Eastern Promises didn't exactly set the world on fire, but his performance was the highlight, and I think voters will take the opportunity to honor him not only for this role but also for his overlooked turns in A History of Violence and the Lord of the Rings trilogy.

Best Actress:
Amy Adams, Enchanted
Julie Christie, Away From Her
Marion Cotillard, La Vie en Rose
Angelina Jolie, A Mighty Heart
Ellen Page, Juno

Throughout this awards season, three names kept popping up in this rare — Christie, Cotillard, and Page. So it's pretty safe to assume they'll make it in. That leaves us two spots in a relatively weak year for buzzed-about performances (sadly, Black Book's Carice Van Houten has no traction whatsoever). With very little competition, Jolie should make the cut — the film didn't make much of a dent, but her stardom has kept her in the race. The final spot is anyone's guess. High-profile star turns (Jodie Foster in The Brave One, Cate Blanchett in Elizabeth: The Golden Age) have flopped at the box office, while respected performers in independent films (notably Laura Linney in The Savages) have been lost in the year-end shuffle. That leaves Amy Adams in Enchanted, a star-making performance by a previous nominee in a hit movie that's still fresh in people's minds.

Best Director:
Paul Thomas Anderson, There Will Be Blood
Joel and Ethan Coen, No Country for Old Men
Tony Gilroy, Michael Clayton
Sean Penn, Into the Wild
Julian Schnabel, The Diving Bell and the Butterfly

At this point, Best Director is the Coens' to lose. Even if someone else takes home Best Picture, I think it's still their year in this category. I also think the Directors Branch will be impressed by Sean Penn's metamorphosis into serious filmmaker, as well as Schnabel's unconventional, inspired filmmaking choices in Diving Bell. For this year's semi-obligatory non-Best Picture-nominated director, I'm predicting Anderson, a respected maverick whose filmmaking chops in There Will Be Blood are undeniable even if the film itself is too much for some audiences. Of the two remaining Best Picture nominees, I think Gilroy has the edge over Juno's Jason Reitman for two reasons: (1) crowd-pleasing comedies tend to get shut out of this category, and (2) Gilroy is a veteran screenwriter makes an impressive directorial debut. But don't be surprised if another "lone director" — say, Sidney Lumet for Before the Devil Knows You're Dead, or Tim Burton for Sweeney Todd — gets the nod instead.

Best Supporting Actor:
Javier Bardem, No Country for Old Men
Philip Seymour Hoffman, Charlie Wilson's War
Hal Holbrook, Into the Wild
Tommy Lee Jones, No Country for Old Men
Tom Wilkinson, Michael Clayton

In a year without Bardem, this race might have come down to Grand Old Actor Holbrook vs. veteran character actor Wilkinson. But Bardem casts a long shadow over this category, with Chigurh the creepiest villain in an Oscar-feted film since Hannibal Lecter. Charlie Wilson's War wasn't the Oscar juggernaut that it was predicted to be, but I still think Hoffman's scene-stealing turn will make it in. I think this year's biggest surprise will be the absence of Casey Affleck's performance in The Assassination of Jesse James by the Coward Robert Ford. Affleck's the only serious competition Bardem has had among the precursor awards, but Jesse James was a box-office flop and Affleck's performance could give voters the willies. Max Von Sydow's affecting turn in The Diving Bell and the Butterfly might have had a chance here — as a means of honoring one of the world's most esteemed actors and, by extension, his recently-departed longtime collaborator Ingmar Bergman — except that he might not have enough screentime to be a contender. Instead, I'm giving the edge to Jones, an Academy favorite who came roaring back this year to give two acclaimed performances after a decade's worth of commercial crap.

Best Supporting Actress:
Cate Blanchett, I'm Not There
Catherine Keener, Into the Wild
Kelly MacDonald, No Country for Old Men
Amy Ryan, Gone Baby Gone
Tilda Swinton, Michael Clayton

Once again, three names keep popping up in this category: Blanchett, Ryan, and Swinton. I think they'll all get nominated, though who will win remains to be seen (early shot-in-the-dark prediction: a Swinton upset). The other two spots are less certain. But consider that, more than any other category, the Best Supporting Actress nominees are largely composed of performers who starred opposite other Oscar nominees. In this respect, I think contenders such as Ruby Dee in American Gangster, Marisa Tomei in Before the Devil Knows You're Dead, and especially Saoirse Ronan in Atonement, are at a disadvantage here. Instead, I'm predicting the fourth spot to go to Catherine Keener, getting her third nomination in this category for her moving turn in Into the Wild. The final slot comes down to Jennifer Garner in Juno and Kelly MacDonald in No Country for Old Men. Despite Garner's greater name recognition, I'm giving the edge to MacDonald, both for No Country's frontrunner status and for playing one of Oscar's favorite characters, the supportive, long-suffering wife. But honestly, it could go either way.

Watch for the Oscar nominations tomorrow, January 22. And remember, nobody knows anything.
