A team of "sub-zero heroes" band together to save a human infant in this digitally animated feature from Oscar-winning director Chris Wedge, whose unique lighting software (called "Ray Tracing") sets his visual style apart from earlier CGI efforts. Twenty thousand years ago, the Earth is overrun by freezing temperatures in an Ice Age that is sending all manner of critters scattering in the path of encroaching glaciers. When a lost human infant is discovered, an unlikely quartet of misfits forms to return it to its mother: Manny, a depressed woolly mammoth (Ray Romano); Sid, a fast-talking sloth (John Leguizamo); an acorn-crazed squirrel named Scrat (Wedge); and the devilish saber-toothed tiger named Diego (Denis Leary). Before they can complete their mission, the reluctant compatriots will brave pits of boiling lava, dangerous caverns of ice, and even a traitorous plot within their midst. Ice Age (2002) also features the voices of Jack Black, Jane Krakowski, and Goran Visnjic.
