Just in case anyone had the slightest doubt, Pixar is going to receive another Oscar nomination for Best Animated Feature and is the putative frontrunner for its latest instant classic, “Up.” Arguably Pixar’s funniest, most touching and most beautifully drawn feature, it’s a massive artistic achivement that draws inspiration from sources as disparate as “The Wizard of Oz” and, no kidding, “Fitzcarraldo.” Defying naysayers who have been predicting “Up” would end Pixar’s astounding winning streak, this literally transporting entertainment should also prove a box-office smash — no small achievement for a concept centering on a 78-year-old protagonist that would never have made it past a pitch meeting at DreamWorks. I’ll have a full review next week.
