Chicken Little (2006)

This epic tale presents a new twist to the classic fable of a young chicken who causes widespread panic when he mistakes a falling acorn for a piece of the sky. In this hilarious adventure, Chicken Little is determined to restore his reputation. But just as things are starting to go his way, a real piece of the sky lands on his head! Suspense, chaos, and plenty of laughs ensue as Chicken Little and his band of misfit friends, Abby Mallard (aka Ugly Duckling), Runt of the Litter and Fish Out of Water, attempt to save the world without sending the town into a whole new panic.
