March of the Penguins producers National Geographic Films team with An Inconvenient Truth producers Paramount Vantage to take viewers on an epic journey into the arctic wilderness in a documentary that explores what happens when the beautiful frozen world occupied by two majestic creatures gradually begins to melt away. Seela is a mother walrus thriving in the chilly waters of the Great North, and Nanu is a polar bear with curved claws that make it easy to maintain her footing on ice. As director Sarah Robertson follows these two remarkable creatures from birth through adolescence, maturity, and, ultimately, parenthood, viewers will bear witness to the cycle of life as it unfolds in a vast frozen landscape that could pose problems for all of humankind if it continues to thaw at the current rate. ~ Jason Buchanan, Rovi
