I'll have to check out Brazil- I remember seeing the cover at Blockbuster when they still had stores but I've never watched the movie.
I've always thought Huxley was born about 100 years too early, as his ability at writing witty repartee on outside of the box ideas is truly top notch. If he were writing today he'd be movies and we'd put him on par with Jon Favreau or Quinton Tarantino.
Anyway, my understand is Orwell came up with the idea for 1984 while he was in the hospital recovering from a neck wound he received from Marxist sympathizer fighting the government in Spain. After that he was sort of done with Stalin apologists and it's reflected in both 1948 and Animal Farm. Another book he wrote that goes after the communists, but with Animal Farm instead of control of the media he points his aim toward the top down structure of the Communist collective farm system and it's effect on all the beasts who live there...
