Animal Farm without warning and destroys the windmill. The book's close, with the pigs and men in a kind of rapprochement, reflected Orwell's view of the 1943 Tehran Conference that seemed to display the establishment of "the best possible relations between the USSR and the West" – but in reality were destined, as Orwell presciently predicted, to continue to unravel. The disagreement between the allies and the start of the Cold War is suggested when Napoleon and Pilkington, both suspicious, each "played an ace of spades simultaneously". Similarly, the music in the novel, starting with "Beasts of England" and the later anthems, parallels "The Internationale" and its adoption and repudiation by the Soviet authorities as the anthem of the USSR in the 1920s and 1930s. Adaptations Stage productions In 2021, during pandemic restrictions, the National Youth Theatre toured a stage version of Animal Farm; this run included outdoor performances on a farm at Soulton Hall. A solo version, adapted and performed by Guy Masterson, premiered at the Traverse Theatre Edinburgh in January 1995 and has toured worldwide since. 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 new adaptation written and directed by Robert Icke, designed by Bunny Christie with puppetry designed and directed by Toby Olié opened at the Birmingham Repertory Theatre in January 2022 before touring the UK. Films 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 film, in which Napoleon is eventually 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 live-action TV version that shows Napoleon's regime collapsing in on itself, with the farm having new human owners, reflecting the collapse of Soviet communism. Andy Serkis is directing an upcoming animated film adaptation. Radio dramatisations 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
