There was a lot of thought put into this TV series, which was not your typical Western. For one thing, his name: a Paladin was a lawful knight of Charlemagne's court. This accounts for the chess-piece knight on his calling card, and the lyrics of the theme song which refer to him as "a knight without armor in a savage land." His calling card said "Have Gun, Will Travel" and "Wire Paladin, San Francisco." (By the way, "Wire" was not his first name, it's a verb meaning "send a telegram.") Paladin, the only name he ever went by, was a true split-personality type. He was equally at home wearing expensive suits and living a rich playboy lifestyle in a San Francisco hotel, or donning his black working clothes, and avenging evil. Some of the clients he stood up for were not in the majority; for example, he once defended the Mennonites, which probably would make him seem to be a non-conformist. Paladin only cared about right and wrong. Even though he charged a fee for his services, he only took cases he believed in, and clients he wanted to help.
" 'Have Gun, Will Travel' reads the card of a man. A knight without armor in a savage land. His fast gun for hire heeds the calling wind. A soldier of Fortune is the man called Paladin. Paladin, Paladin, where do you roam? Paladin, Paladin, far, far from home."
