[7] She met John Halas after he advertised for an assistant animator for British Colour Cartoons Limited.

[5][7] The company's first commissions consisted of commercials for Kellogg's cereal and Lux Soap, creating Train Trouble and Carnival in a Clothes Cupboard respectively.

[7] Later in 1940, Halas and Batchelor was taken over by the Ministry of Information, and used to create propaganda and educational films for the war effort.

[5] Because John Halas was a Hungarian immigrant, Batchelor helped inform the films with her knowledge of the British way of life.

The series was designed to educate and persuade the audience in regard to the socialist-slanted policies of the newly installed Labour Government.

To that end, Lothar Wolff, in charge of commissioning films for the ECA, asked Halas and Batchelor to animate The Shoemaker and the Hatter (1949).

Wolff later introduced their films to Louis de Rochemont, who worked with them to create Animal Farm.

The breakdown chart was used to connect all the characters in Animal Farm to each other, as well as gauge their contribution to major plot points.

[4] The charts helped to decide which characters (for example, Clover and Mollie) could be dropped from the film, and which scenes could be shortened while still retaining the story and message of Animal Farm.

[7] The studio's short, Automania 2000 (1963), for which Batchelor wrote the script, won the British Academy of Film and Television Arts award in 1964,[10] and was nominated for an Oscar.

[5] In creating the adaptation, Batchelor had to conform to a strict condition that no songs or dialogue could be altered, which was challenging when trying to shorten the film to feature-length.

[7] Halas and Batchelor also animated the well-known music video for the song "Love Is All" by Roger Glover (1975).
