While I obviously can't review this set since it hasn't been released yet, I hope Timeless Video does a better job than so many of their other releases of old TV series. (See Amazon reviews on any other Timeless releases on DVD, with the exception of The Virginian which they have done a good job on.)
As for the series itself, it is interesting how series with the same basic plot are released the same year and usually last the same amount of time. This show ran on NBC Thursday nights, it concerned rodeo rider Earl Holliman who travels the rodeo circuit with his younger brother, Andrew Prine. I watched it although I have no specific memories of specific episodes. The same year this series premiered on NBC, 1962, another rodeo show debuted on ABC: Stoney Burke with Jack Lord and a great supporting cast including Warren Oates and Bruce Dern. Both these rodeo series lasted 1 year and were cancelled. It is interesting how often we see this: The Munsters and The Addams Family, both premiered on CBS and ABC in 1964, and both lasted 2 seasons and were cancelled. Two serious Doctor series, Dr Kildare and Ben Casey, premiered in 1962 on NBC and ABC, and both left the air in 1966. It was the same with Marcus Welby, MD and Medical Center, which premiered in 1970 on ABC and CBS, both lasting 7 years until cancellation. I can go on and on about this phenomenon, but I won't any further.
In conclusion, what little memory I have of Wide Country was that it was a good series (Why else would I have watched it? I only hope that Timeless Video does it justice.
