One of my favorites is "Long Live Walter Jamison," which explored immortality and its possible drawbacks.
“I don’t believe what you describe is a TZ episode, although the series did depict some totalitarian regimes. “The Obsolete Man” was one of them, starring Burgess Meredith.”
Yeah, it could have been an Outer Limits one. Can you think of any other SciFi series back then that it could have been? My memory seems to have faded somewhat. But I do remember the similarity to the theme there and what’s going on today. I can even remember the face of the poser they had playing the pretenda supreme leader.
“The Obsolete Man” is one of my favorites.
