This tremendous tale of an old man realising his life's dream courtesy of a clapboard house hoisted into the air by helium balloons could be Pixar's finest moment. Ed Asner voices the old grouch who reluctantly finds himself teaming up with a chirpy wilderness scout as they venture deep into the South American jungle. Awe-inspiring computer animation is more than matched by rich characterisation and a surreal plot that proves wrenchingly poignant and heart-stoppingly exciting. And - ta-da! - another Best Animated Feature Oscar for Pixar's mantelpiece.
