This film was the first successful theatrical cartoon produced by the UPA animation studio, after their initial experiments with a short series of cartoons called The Fox and the Crow. It was meant to be an artistic attempt to break away from the ultra-realism in animation that had been developed and perfected by Walt Disney. While Disney's animation methods produced lush and awe-inspiring images, it was felt that realism in the medium of animation was a limiting factor. Cartoons did not have to obey the rules of the real world (as the short films of Tex Avery proved), and so UPA experimented with a non-realistic style that depecticted caricatures rather than lifelike depictions of real people. This was a major step in the development of limited animation - though despite the abuse of the form that would arise in the future (due to cost-cutting methods), Gerald McBoing Boing was meant as an artistic exercise rather than merely a way of producing cheap cartoons.
The complete UPA series is as follows:-
