This film's release in South Africa again depicted just how paranoid the then government of the day was: the Security Police found ads in local papers, placed anonymously and giving words like "Condor", "Control", "Assassination", "Spies" and a telephone number in Johannesburg, obviously the number of a subversive organization wanting to bring down the lilywhite govt. of the day.
The number given on each of the ads was that of the film distribution offices that were marketing
Three Days Of The Condor.
