The story of married animators, John Halas and Joy Batchelor. A Jewish emigre from Hungary and a working class woman from Watford, England, John and Joy fell in love, created cartoons that helped the allies to win the war, and produced the first feature-length animation in British cinema history, Animal Farm (1954).

BBC Four’s new documentary takes us on a journey through more than a century of animation. It examines the creative and technical inventiveness of some of the great animation pioneers who have worked in Britain – trailblazing talents such as Len Lye, John Halas and Joy Batchelor, Joanna Quinn, and Bristol’s world-conquering Aardman Animations.
