Hailed as one of the greatest films of all time, The Incredible Mr. Limpet is a story about the wonders of imagination and the triumph of the spirit. Live-action and 2-D animation combine to tell the story of a man who longs to be a fish after he is classified by the Navy as an F4 - too small and too weak to be a soldier. When his dream of being a fish becomes a reality, Henry uses his underwater prowess to become the Navy's strongest secret weapon.
