Despite good ratings, the series was canceled after two seasons, following disagreements between Richard Boone and Universal.
Richard Boone, Rick Lenz, and Harry Morgan would appear together again in John Wayne's final film, Le dernier des géants (1976).
In the fall of 1972, NBC moved its successful Wednesday night Mystery Movie series consisting of "Columbo," "McCloud," and "McMillan and Wife" to Sunday nights and added a fourth show, "Hec Ramsey," while turning the original slot over to three new mysteries ("Banacek," "Madigan," and "Cool Million"). "Hec Ramsey" was a product of Jack Webb's then prolific production company. The series, which ran for two seasons (a total of ten 90 minute to 2 hour episodes) was superficially a Western, but it was set in the waning days of the Wild West when science was beginning to play a more significant role in crime solving than gunplay.
Ramsey mentions that he was, in his younger days, a gunfighter. While not proof positive-many lawmen were former gunslingers and some were even criminals-it's possible that Ramsey was the older version of "Palladin" from [ink=tt0050025]. Likewise, changing one's name was easy back then. It's possible that "Hec Ramsey" and "Clay Alexander" (a name given Palladin in a novel based on the series) were pseudonyms.
One of the original spokes of NBC's popular Mystery Movies rotating with the likes of Columbo, McCloud, etc. Sadly, terms between Richard Boone and Universal deteriorated resulting in only 10 episodes being produced
