Among my growing list of signs the Mayans are probably right about 2012 — in addition to a Harvard-educated Asian American Christian taking the NBA by storm — would have to be Pixar’s omission from the Best Animated Film Oscar nominees. Sure, pointing out that Cars 2 didn’t make the cut probably stokes as much indifference as hearing your spoiled cousin whine about only getting an Audi for her sweet 16. Nonetheless, Pixar’s sole rep at the Theater-Previously-Known-as-Kodak this year is director Enrico Casarosa, whose La Luna was nominated for Best Animated Short.
