"Animal Farm", 1954 British animated film based on George Orwell's novella

I vaguely remember “Animal Farm” from 1954, based on George Orwell’s novella to satirize communism (“some animals or more equal than others”), and imdb lists it as a 72 minute animated film, by Joy Batchelor and John Harris, from Louis de Rochment in the UK and France.

I think it played at the KB Ontario on Florida Ave in Washington, which used to play mostly foreign films then.

YouTube has a longer 120 minute version. The novella was inspired by the story of Welsh journalist Gareth Jones who “spied” on the Soviet Holodomor in 1933.
