Claude Akins and Barry Atwater had the previous year co-starred in the classic episode of The Twilight Zone (1959) titled The Monsters Are Due on Maple Street (1960), and would over a decade after this episode portray Sheriff Butcher and vampire Janos Skorzeny, respectively, in The Night Stalker (1972), the first of two TV movie pilots for the series Kolchak: The Night Stalker (1974). They would also work together once more a year later in an episode of Police Story (1973) titled The Ten Year Honeymoon (1973).
Last of four appearances in the series by Claude Akins.
Wagon Train Tracker: Reference us made to the train being near St. Joseph, Missouri. Reference is also made to "Benton's Fort" coming up on the trail, but that would entail striking northwest off the Oregon Trail and going to Fort Benton in north central Montana. So the train is likely in southeastern Nebraska, moving west along the Oregon Trail.
