Despite this year's best picture race being unprecedented—10 nominees, etc.—all of the prognosticators think we're down to a two-horse race, “The Hurt Locker” and “Avatar,” and they all point out the obvious differences between the two: $2.5 billion worldwide (and counting) vs. $18 million worldwide (and not); sci-fi fantasy vs. gritty reality; Cameron vs. Bigelow. But everyone's ignoring the most crucial difference:

The sci-fi fantasy set on a moon in a far-off galaxy is a greater critique of the Bush administration than the gritty war film set in Baghdad in 2004.

Make of that what you will.

As for which will win? As I said, we're in unprecedented territory. But let me resurrect a chart from last June showing the annual box office rankings of the various best picture nominees for the last 18 years, with the eventual winner in red:

 The Annual Box Office Rankings for Best Picture Nominees, 1991-2008*

* Best picture winner in red.

Even when the Academy went rogue in 2004 and stopped nominating any picture that was popular, they still went for the first- or second-highest-grossing film among the nominees. Only once in the last 18 years, in 1999, did they pick outside the top two: “American Beauty,” which was still third.

As for how the box-office rankings look this year?

So “Hurt Locker” has all of those bonafides but...131st? That would be unprecedented. As would a sci-fi pic winning best pic. So pick your unprecedenteds.

The only other movie that seems to have a chance is “Inglourious Bastards.” Lotsa noms, did OK at the box office, beloved by critics, it's Holocausty-y, and, one imagines, it's getting the Harvey Weinstein push. Plus it won the SAG ensemble award, and there are more actors in the Academy than any other profession. It would be a good split-the-difference vote anyway.

My guess is “Avatar” but don't bet the house on it.

My choice is “Up.”
