City was excellent
my favorite, though was the Doomsday Machine.
The Doomsday Machine was written by another outstanding Sci Fi author, Norman Spinrad.
Yep I liked the Doomsday Machine also. William Windom as the commodore of the USS Constellation turned in a great performance.
I actually met him once and was almost flattened by his ego. OTOH, Ray Bradbury and Jerry Pournelle (a bit loud) were pretty good guys. Bradbury was very old but still pretty sharp.
If you read the story about HOW the actual script came to be for The City on the Edge of Forever, you will find out who REALLY wrote the screenplay. But the way that the rules in Hollywood work, Ellison “wrote” the show.
