It is 1984 and the world is now a dark dystopia of authoritarian rule by Big Brother, who uses disinformation and lies to control the population (with brutal security forces as well if all else fails). Winston Smith (John Hurt) is a low-level party operative whose job is to literally rewrite history to present the reality Big Brother wants, and to be happily consumed by the brain washed population. Smith however, is not a true believer and writes subversive thoughts in his diary.
He meets and falls in love with Julia (Suzanna Hamilton), another party operative who also wants something more than Big Brother will allow. They begin a secret (and illegal) love affair. Winston is contacted by a higher up party official (Richard Burton) who appears to be part of an underground movement. However, once again all is not what it seems and the secret double life of Smith and Julia soon comes crashing down...
The world building here is top notch, the world of Big Brother is dark and terrifying (especially the torture scenes) and also a warning to us all. A very good film. This was Richard Burton's final film before his death.
