Animal Farm has been adapted to film twice. Both differ from the novel and have been accused of taking significant liberties, including sanitising some aspects.
- Animal Farm (1954) is an animated feature in which Napoleon is apparently overthrown in a second revolution. In 1974, E. Howard Hunt revealed that he had been sent by the CIA's Psychological Warfare department to obtain the film rights from Orwell's widow, and the resulting 1954 animation was funded by the agency.
- Animal Farm (1999) is a TV live action version that shows Napoleon's regime collapsing in on itself, with the farm having new human owners, reflecting the collapse of Soviet communism.
In 2012, a HFR-3D version of Animal Farm, potentially directed by Andy Serkis, was announced.
A BBC radio version, produced by Rayner Heppenstall, was broadcast in January 1947. Orwell listened to the production at his home in Canonbury Square, London, with Hugh Gordon Porteous, amongst others. Orwell later wrote to Heppenstall that Porteous, "who had not read the book, grasped what was happening after a few minutes."
A further radio production, again using Orwell's own dramatisation of the book, was broadcast in January 2013 on BBC Radio 4. Tamsin Greig narrated, and the cast included Nicky Henson as Napoleon, Toby Jones as the propagandist Squealer, and Ralph Ineson as Boxer.
A theatrical version, with music by Richard Peaslee and lyrics by Adrian Mitchell, was staged at the National Theatre London on 25 April 1984, directed by Peter Hall. It toured nine cities in 1985.
A solo version, adapted and performed by Guy Masterson, premièred at the Traverse Theatre Edinburgh in January 1995 and has toured worldwide since.
In 1950 Norman Pett and his writing partner Don Freeman were secretly hired by the British Foreign Office to adapt Animal Farm into a comic strip. This comic was not published in the U.K., but ran in Brazilian and Burmese newspapers.
