Lionel Jeffries directed Water Babies, a children's fantasy based on the story by Charles Kingsley that incorporates live-action and animation in the tradition of The Incredible Mr. Limpet. In Dickensian London, a 12-year-old chimney sweep's apprentice named Tom (Tommy Pender) has to put up with his boss, Grimes (James Mason), and his heavy drinking. One day, in the home of a client, Tom is accused of stealing the silverware. Tom makes a run for it and leaps into a pool, where he comes across a collection of animated characters. While submerged he helps to rescue water babies, children held hostage by an eel and a shark.~ Paul Brenner, All Movie Guide
