Every penguin has a song in his heart. Except musically challenged Mumble. In frozen Antarctica, where penguins sing to woo a mate, Mumble's talent is dancing: When his fellow penguins start to croon, Mumble's feet want to move. Even worse, Gloria, the object of Mumble's affection, only wants to hear a song from Mumble's heart. But when encroaching fishermen threaten the penguins, the colony is saved by Mumble's valor, and Gloria's heart is won by his dancing, Happy Feet. Directed by George Miller, choreographed by Savion Glover and featuring the voices of Hugh Jackman, Nicole Kidman, Robin Williams and crocodile hunter Steve Irwin.
