The live US anthology series, Playhouse 90, premiered on 4 October 1956 with this 90-minute story directed by John Frankenheimer (who helmed 27 episodes), with Rod Serling adapting Pat Frank’s Cold War thriller novel, Forbidden Area, about Soviet sleeper agents trying to sabotage the US war effort.
The story starred Charlton Heston, Tab Hunter, Diana Lynn, Vincent Price, Charles Bickford and a pre-Addams Family Jackie Coogan. It is hosted by Jack Palance. Vincent and Tab would go on and appear together in the 1965 AIP adventure, War-Gods of the Deep, in which Vincent played the Nemo-esque Sir Hugh opposite Tab’s Pat Boone-styled hero. Forbidden Area, however, is made of much sterner stuff.
