Cog notes

Cog fights national cinema as it gives a realistic presentation of Rio. Murder rate in Paris is 2 in 100,000 Rio is 40 in and the slums are unknown but believed to be much higher.
During seventies there is an overpowering feeling of claustrophobia due to the high rise buildings.
1980s most scenes filmed at night to show the danger of the city through the suggestion that most events in the CoG occur at night.
