Just watched The Corbomite Maneuver for the first time in awhile. There's a beautifully-composed shot in Act 3 that shows how much love and care was being put into the show early on:
The shot begins with Sulu and Scotty talking in the background. Then they go out of focus as Kirk and Spock continue the scene.
This was the only episode Joseph Sargent directed. Other directors subsequently did great things on the show, but nothing quite like this. As this was the first episode photographed by Jerry Finnerman, maybe he was eager to show what he could do?
It's almost dream-like filmmaking, really.
