Spin Off
Creators of The Rifleman wanted the show to bring moral values to the viewers that tuned in each week. Especially the ones related to his son Mark. Lucas was constantly teaching Mark the right and wrong way to do things, and he had a little help from his friends. One of which was the “Plainsman” character played by Michael Ansara, even though he only made an appearance in two installments of the show. Ansara did such a good job he was offered his own show called Law of the Plainsman in 1959.
