Animal Farm is a 1954 British-American adult animated drama and propaganda film commissioned by the American Central Intelligence Agency (CIA). and directed by both John Halas and Joy Batchelor, and produced by Halas and Batchelor, based on the 1945 novel of the same name by George Orwell. It was the first British animated feature (Water for Firefighting and Handling Ships, two feature-length wartime training films, were produced earlier, but did not receive a formal cinema release). Although the film was a financial disaster, it quickly became a staple of classrooms in America and Britain.
The film rights for a movie adaptation of Animal Farm were bought from Orwell's widow after she was approached by agents working for the Office of Policy Coordination (OPC), a branch of the CIA that dealt with the use of culture to combat communism.There are many differences between the animated movie and the original book, changes which were made on request by the Americans to solidify the anti-socialist message of the film.
Maurice Denham provided the voice for all the animals in the film.
