Every version of Three Days of the Condor — the films & series, compared across media.
Joe Turner — a bookish CIA researcher — returns to find all his co-workers dead, and suddenly no one can be trusted. That premise of betrayal inside American intelligence connects both versions of Three Days of the Condor. The 1975 film follows Turner's desperate bid to outwit those responsible; the 2018 series Condor revisits the same character as a young analyst whose own work is turned against him and the public.
Both the 1975 film Three Days of the Condor and the 2018 series Condor share the same core character and premise — CIA analyst Joe Turner navigating institutional betrayal — but the synopses do not confirm a common literary source.
There are two screen versions: the 1975 thriller film Three Days of the Condor and the 2018 TV series Condor, which updates the premise for a contemporary setting involving mass surveillance.
The 1975 film Three Days of the Condor centres on Turner evading the people who killed his colleagues; the 2018 series Condor centres on Turner discovering the CIA misused an algorithm he built. Either works as an entry point depending on whether you prefer film or series.
