Michael Ansara first played his character in this series on 17 Feb 1959 in the episode "The Indian" and again on 9 June 1959 in the episode "The Raid," both on the series The Rifleman (1958), but neither actually plays like a pilot for this program.
In 1966, Four Star Productions syndicated four of its half-hour Western series under the title of "The Westerners." They were "The Black Saddle," "Johnny Ringo," "Law of the Plainsman," and "The Westerner." The series had a new opening credits sequence featuring Michael Ansara, Peter Breck, Don Durant, and Brian Keith. Keenan Wynn appeared in new opening and closing host segments. The original closing credits were retained.
