Based on the novel by Theodore Pratt, this quaint fantasy leads the viewer from real-life to a spectacular animated deep-sea adventure. Henry Limpet (Don Knotts), a bespectacled, milquetoast bookkeeper, loves his pet fish so much that he longs to be one. When Henry's wish comes true and he's turned into a talking fish, the simple ocean life he'd envisioned proves more exciting than mundane. This is a campy, funfilled movie for all ages. :)
Meek and mild mannered bookkeeper Henry Limpet has few passions in life. It's mid-1941 and he would love to join the Navy but has been rated 4F. His friend George Stickle is in the Navy and lays it on pretty thick. If Henry could have one thing it would be to become a fish. While on a visit to Coney Island, Henry falls into the water and miraculously gets his wish. Now a fish, he makes friends, Ladyfish and Crusty the hermit crab and loves his new life. He also uses his abilities to help the US Navy locate and sink Nazi U-Boats, forcing the Germans to create a new weapon to deal with the Allies secret weapon. When years later the Navy finds intelligent activity among dolphins, they may also know who is teaching them.
