Check a movie called nineteen eighty four. after a nuclear war the world is divided into 3, the area where this movie takes place is called oceania. The people are kept as slaves and are fed propaganda through the telescreen ( a t.v. and surveillance video camera in one). They also have something called thoughtcrime police as in this future the ones in control do not want the people to do any thinking against the rulers. A man tries to save and free the people. thie movie is a real mind fuck. also kinda creepy relevance to today's modern world.
