Quick trivia: One of the few (if not only) shows which began on television and was adapted for radio, rather than the other way 'round (John Dehner was Paladin on radio).
I remember the opening sequence, showing that knight's head holster, accompanied by a snip of dialogue from this weeks' episode. Even at my tender age, I noticed that Paladin seemed to be really p***d off about something most of the time.
The series is well done-but always had a cold, impersonal feel. Probably fitting for a show about a hired gun.
