Nineteen Eighty Four is a novel written by George Orwell, published in 1949. The book is an expose written in allegorical form on collective oligarchical control of entire nation states that are constantly being pitted against each other under false pretenses of national security.
A 1984 British movie adaptation of Nineteen Eighty Four was made. Several cosmetic differences exist in the film (people referring to each other as 'brothers' and 'sisters', the crossed-hands pose/salute used by both the military and the populace) but on the whole it's fairly accurate to the book.
Terry Gilliam's Brazil (working title: Nineteen Eighty Four 1/2) is considered to be a spiritual successor/dark parody of Nineteen Eighty Four.
The original name of the book was to be 'The Last Man in Europe' - later changed to '1948' and thereafter settling on '1984', or 'Nineteen Eighty Four'.
Given that the ruling party in Oceania, Ingsoc, is Newspeak for English Socialism, it is ironic that the Fabian Society was founded in the year 1884 - which would make 1984 the hundred-year anniversary of the group.
George Orwell worked for the BBC at one point and distinctly remembers fudgeting the general statistics of ration food to create the appearance that the British public were being well-nourished in comparison to pre-war days. In the book and film, the protagonist, Winston, undergoes a similar experience at the Ministry Of Truth.
