Cimarron Strip aired on CBS in the USA from September 1967 to March 1968. Its star was Stuart Whitman who played the role of Marshal Jim Crown. (The series was produced by the same people who produced Gunsmoke).
The format was for a series of approx 90 minute westerns (including adverts), and was very similar to The Virginian in its style.
Set in Oklahoma, but used many locations for external shooting eg Alabama, Utah and Tuscon.
This is the very first episode (of only 23 ever made, the series was cancelled after just one season). Its theme music was composed by Maurice Jarre.
The stories being longer than the usual 30 minutes or so, gives time for more character development. The film quality has aged somewhat, however these are good stories and are examples of 1960s westerns done well.
