Episode complete credited cast:


The Enterprise shuttlecraft, carrying Kirk, Spock, Dr. McCoy and critically ill Federation Ambassador Nancy Hedford, encounters a mysterious energy cloud which pulls them down to planet Gamma Canaris N. There they meet a castaway, a young man who purports to be Zefram Cochrane, inventor of the Warp Drive over 100 years ago. In history he had lived to be 80 years of age before disappearing somewhere in space. Apparently the same energy cloud which brought the shuttlecraft to the planet also found and rejuvenated Cochrane, making him effectively immortal. Unless Kirk can get themselves released soon, the ambassador, without vital medical treatment, will die. Written by Clive Wilson

Captain James T. Kirk: The Enterprise is waiting, Mr. Cochrane.
Zefram Cochrane: I can't take her away from here. If I do, she'll die. If I leave her, she'll die of loneliness. I owe everything to her; I can't leave her. I love her. Is that surprising?
Mr. Spock: Not coming from a human being. You are, after all, essentially irrational.
Captain James T. Kirk: Think it over, Mr. Cochrane. There's a whole galaxy out there waiting to honor you.
Zefram Cochrane: I have honors enough.
Mr. Spock: But you will age, both of you. There will be no immortality; you'll both grow old here and finally die.
Zefram Cochrane: ...

A Gentle Story of Love and Affection
29 April 2014 | by (United States) – See all my reviews

Zafram Cochrane, one of the pioneers of space science is on a planet. He has been for more than a hundred years. He has been kept alive by his association with an entity that looks like a little whirlwind that encompasses him, sparkling and turning. This turns out to be an act of passion and love. The problem is that Cochran is stuck there, not only because he is not allowed to leave but because he has feelings for this entity. Kirk and his crew come along, accompanied by a young woman who has been given a death sentence. She is played by Elinor Donahue, who played the eldest daughter on "Father Knows Best" and one of Andy Griffith's girlfriends on his show. She is bitter and angry, which is natural. Cochrane is attracted to her, but she is too into her misery to really allow this. I always liked this episode because there is a real humanity to it. A gentleness. Glenn Corbett, a guy we used to see all the time does a nice job of playing the low key Cochrane.
