The film rights for a film 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. Although the film was a financial failure and took 15 years to generate a profit, it quickly became a staple in classrooms across the United Kingdom, the United States and other English-speaking countries like Australia, Canada, and New Zealand into the 1980s.

It was based on the 1945 novel of the same name by George Orwell.

It was produced by Halas and Batchelor and funded in part by the Central Intelligence Agency (CIA), who also made changes to the original movie script. Animal Farm is a 1954 adult animated film directed by animators John Halas and Joy Batchelor.
