The CIA secretly purchased the film rights to several novels written by George Orwell to alter their endings. The most notable examples are the animated film adaptation of Orwell's "Animal Farm" (1954) and the live-action adaptation of "Nineteen Eighty-Four." In the case of "Animal Farm," the CIA changed the original book's ending, which critiques both communism and capitalism, to a more overtly anti-communist ending in the film where the animals successfully revolt against the pigs. Similarly, the ending of "Nineteen Eighty-Four" was reportedly influenced by the CIA to present a different conclusion than Orwell's original. These alterations were part of the CIA's efforts to use culture as propaganda during the Cold War.
