A BBC radio version, produced by Rayner Heppenstall, was broadcast in January 1947. Orwell listened to the production at his home in Canonbury Square in 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 Four. Tamsin Greig narrated and the cast included Nicky Henson as Napoleon, Toby Jones as the propagandist Squealer, and Ralph Ineson as Boxer.
Animal Farm has been adapted to film twice. The 1954 Animal Farm film was an animated feature and the 1999 Animal Farm film was a TV live action version. Both differ from the novel, and have been accused of taking significant liberties, including sanitising some aspects. In the 1954 version, Napoleon is apparently overthrown in a second revolution. The 1999 film shows Napoleon's regime collapsing in on itself, with the farm having new human owners, reflecting the collapse of Soviet communism, appropriating the new political reality to the story. In 2012, a HFR-3D version of Animal Farm potentially directed by Andy Serkis was announced.
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.
