Animal Farm is a 1954 animated drama film directed by documentarians John Halas and Joy Batchelor. It was produced by Halas and Batchelor and funded in part by the Central Intelligence Agency (CIA), who also made changes to the original script.^[7][8][9] Based on the 1945 novel of the same name by George Orwell, Maurice Denham provides the voice for all the animals in the film.^[10]

The rights for a film adaptation were purchased from Orwell's widow Sonia 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.^[11]

Although a financial failure, taking fifteen years to generate a profit, the film quickly became a staple in classrooms across the United Kingdom, the United States^[12][13][14] and other English-speaking countries like Australia, Canada and New Zealand into the 2000s.

Manor Farm is mismanaged by its drunken owner, Mr. Jones. Prize pig Old Major encourages the farm animals to oust Jones, and teaches them the revolutionary song "Beasts of England" before his death. Due to not being fed, Major's successor Snowball leads the animals into the storehouse for food; then leads them into chasing Jones away, renaming the farm "Animal Farm", and destroying the tools of oppression that had been used against them. They decide against living in the farmhouse, though Saddleback boar Napoleon is interested and begins to secretly raise an abandoned litter of puppies.

The Commandments of Animalism are written on a barn wall, the most important being: "All animals are equal". The farm runs smoothly and food becomes plentiful. The pigs become the leaders and claim special food items "by virtue of their brainwork". Snowball suggests a windmill, while Napoleon opposes it and has his dogs chase Snowball off the farm, denouncing him as a traitor and declaring himself leader. He abolishes farm policy meetings, appropriates all decision-making, and advances the windmill plan that he had snubbed when his rival proposed it.

The pigs alter their laws. "No animal shall sleep in a bed" becomes "No animal shall sleep in a bed with sheets". Napoleon trades the hens' eggs for jellies and jams from Mr. Whymper. The hens revolt by throwing their eggs at the pigs when the pigs attempt to seize the eggs by force. To impose his will through fear, Napoleon holds a show trial where a sheep and a duck are accused as traitors and butchered by the dogs. Their blood is used to append to the commandment "No animal shall kill another animal" the words "without cause". Napoleon bans "Beasts of England", declaring the revolution complete and the dream of Animal Farm realised.

Jealous farmers attack Animal Farm and Jones blows up the windmill with himself inside. The animals win the battle at a great cost of lives. Boxer the workhorse, wounded, works to rebuild the windmill until he is gravely injured in an accident. Napoleon has a van take Boxer away, which Benjamin the donkey recognises as being from Whymper's glue factory. Napoleon's second-in-command Squealer delivers a sham eulogy, claiming Boxer's last words were to glorify Napoleon. The animals see through the propaganda but are driven away by the snarling dogs. The pigs toast Boxer's memory with whisky they bought with his life.

Years pass and Napoleon has expanded the neighbouring farms into an enterprise. The pigs walk upright, carry whips, drink alcohol and wear clothes. The Commandments are reduced to a single phrase: "All animals are equal, but some animals are more equal than others". Napoleon holds a dinner party for a delegation of outside pigs, who congratulate him on having the hardest-working and lowest-consuming animals in the country. They toast a future where pigs own farms everywhere. Benjamin imagines the pigs have taken on the likeness of Mr. Jones.

Acknowledging their situation is even worse than before the revolution, the animals storm the farmhouse. The guard dogs are too drunk to act (having been given full access to the distillery) while the animals smash through the house, trample Napoleon and the pigs to death, and reclaim the farm along with their freedom.

The film was rated "U" (Universal), fit for audiences of all ages.^[20]

Much of the pre-release promotion for the film in the UK focused on it being a British film instead of a product of the Hollywood studios.^[21]

Scenes from Animal Farm, along with the 1954 TV programme Nineteen Eighty-Four, were featured in "The Two Winstons", the final episode of Simon Schama's program A History of Britain broadcast June 18, 2002.

Four decades after the release of Animal Farm, Cold War historian Tony Shaw discovered, through looking at archives of the film, that the CIA had secretly purchased the rights to the film. The CIA also altered the ending of the film so that the pigs, who represent communists, were overthrown by the other animals on the farm.^[22]

Film critic C. A. Lejeune wrote at the time: "I salute Animal Farm as a fine piece of work… [the production team] have made a film for the eye, ear, heart and mind".^[23] Matyas Seiber's score and Maurice Denham's vocal performance have been praised specifically (Denham provided every voice and animal noise in the film). The animation style has been described as "Disney-turned-serious".^[24] The movie holds a 69% score at Rotten Tomatoes based on 13 critic reviews.^[25]

Some criticism was levelled at the altered ending, with one paper reporting, "Orwell would not have liked this one change, with its substitution of commonplace propaganda for his own reticent, melancholy satire".^[24]

The film was a box office disaster, posting the weakest financial loss in fiscal year 1954, one of the most expensive recessions of all time. Its budget would not be recovered until fifteen years after release.^[6]
