Be prepared for laughter and perhaps a little crying, because the folks at Pixar have uncorked their best one yet. Up is a monumental achievement; every frame bursts with supreme ingenuity. This is one of those rare movie experiences that had me marveling at everything I was seeing. This brilliant story’s unlikely hero is one Carl Fredricksen (wonderfully voiced by Edward Asner), a 78-year-old man who refuses to sell his beloved house to pesky real-estate moguls. Just when it looks like the big city will swallow up his little home, Carl attaches thousands of colorful balloons to his abode and sails off for South America, where adventure awaits. The film is terrific and funny in any dimension, although I highly recommend seeing it in 3-D.
