For the first time in my life I watched "Three Days Of The Condor", a 1975 film directed by Sydney Pollack, staring Robert Redford. It's based on the book "Six Days Of The Condor". The film is well-known throughout the hacker community because of its realistic depiction of phone phreaking. At one point in the film Robert Redford steals a lineman's handset which he uses to beige box with. He records some DTMF tones and uses a remote computer to decode them. He also makes a call from within a telephone exchange, directly connecting to the switch. This enables him to route his call through several phone lines, thus defeating the CIA's attempt to trace his call.
Watching Three Days Of The Condor made me want to watch "The Falcon And The Snowman" and "The Conversation" again.
