The Incredible Mr. Limpet

Henry Limpet is a mild-mannered bookkeeper with a passion for fish and a deep longing for adventure. His life takes an extraordinary turn when he falls off a Coney Island pier and miraculously transforms into a fish. As a talking fish, he joins the U.S. Navy's fight against German U-boats during World War II, using his underwater knowledge to help locate enemy submarines. Directed by Arthur Lubin, this 1964 family fantasy blends live action with animation, featuring Don Knotts in his first starring film role as the timid Henry, with Carole Cook as his wife Bessie and Jack Weston as his best friend George. Warner Bros. produced the film, which became a modest hit and has since gained a cult following for its unique premise and Knotts' endearing performance.

The film is based on Theodore Pratt's 1942 novel Mr. Limpet, though the screen story expands considerably on the source material. Lubin, who had previously directed the Francis the Talking Mule series and the TV sitcom Mr. Ed, was a natural fit for a talking-animal picture. The underwater sequences were animated by Warner Bros.' legendary animation department, overseen by Robert McKimson, the director responsible for creating Yosemite Sam. Knotts recorded his voice work for the animated segments separately, allowing animators to match the fish's movements to his distinctive vocal tics.

Released on March 28, 1964, the film grossed roughly $4 million domestically, a solid return for a modestly budgeted family picture. It has never been released on a major subscription streaming service in the United States, but it appears periodically on Turner Classic Movies and remains available for digital rental or purchase through Apple TV and Amazon Prime Video.

In the early 1940s, Henry Limpet is a Brooklyn bookkeeper whose heart belongs to the sea. He spends his evenings reading ichthyology texts, his weekends at the aquarium, and his daydreams on the idea of being a fish. His wife Bessie tolerates his obsession with affectionate exasperation, while his practical friend George Stickel teases him about preferring fish to people. When World War II breaks out, Henry tries to enlist in the Navy, but his poor eyesight and unimpressive physique get him rejected. The disappointment deepens his yearning for escape.

On a trip to Coney Island with George, Henry leans too far over a pier railing and falls into the water. Instead of drowning, he transforms into a fish, retaining his voice and personality. The film shifts to animation as Henry discovers a vibrant underwater world. He meets Crusty, a gruff crab who becomes his guide, and a flirtatious ladyfish who takes a romantic interest in him. But Henry soon realizes he can put his new form to good use. With German U-boats terrorizing Allied shipping, he decides to help the Navy.

Henry makes contact with Admiral P.P. Spewter and his staff, including the skeptical officer Harlock. Communicating through a series of underwater signals, he provides precise intelligence on enemy submarine movements. The Navy brass, initially incredulous, come to rely on Henry's reports. As he guides Allied forces to multiple U-boat kills, Henry becomes a secret weapon in the Battle of the Atlantic.

Meanwhile, Henry navigates the challenges of his new existence. He struggles with his longing for Bessie and his old life, even as he grows attached to his underwater companions. The ladyfish's affection complicates matters, and Crusty's grumbling provides comic relief. Henry must balance his duty to the war effort with his personal transformation, all while keeping his identity hidden from the German forces who have begun to suspect something is hunting them.

The film builds toward a confrontation as the German Navy sets a trap for the mysterious creature disrupting their operations. Henry, using his intimate knowledge of the ocean, must outwit the enemy to survive. Along the way, he earns the respect of the Navy and proves that even the most unlikely hero can make a difference.[edit]
