First, there are really two second seasons of TOS. The Gene Coon second season and the John Meredyth Lucas second season. Coon S2 has a lot more humor than Lucas S2. Coon S2 in general has more comedy and action-adventure. Not that Lucas S2 doesn't have action-adventure, but you start seeing episodes like "Return to Tomorrow" which feels a lot more "sci-fi" than a lot of the rest of S2 and gets back to the galaxy feeling wondrous. The galaxy also doesn't feel like it revolves around the Federation in "Return to Tomorrow" and Sargon makes the Enterprise crew feel like the Johnny Come Lately it really is. "By Any Other Name" is the same, when Kelvans take over the Enterprise, modify it, and set course back for Andromeda. It feels more space-y.
This must've around the time Gene Roddenberry started thinking, "We should take the series back toward a more hard sci-fi, mind-bending direction". These two episodes seem to be the point where Gene Roddenberry must've found out what to focus on after Gene L Coon left. John Meredyth Lucas might've been gotten the ball rolling toward this change in direction, but it's Gene Roddenberry who must've decided, "I want to grab this by the horns", and thought, "I'll do it myself!" after John Meredyth Lucas decided not to return for the third season. He was excited, which is why he felt so crushed and so deflated when NBC said "We're moving you to Friday Nights at 10:00!" The bubble just burst, it must've hurt, and he probably felt, "That's it, I'm done." And brought in Fred Freigberger.
So that's the context I've got myself mentally in, before I start watching the last batch of Season 2. So I have to go back further than I intended. I'm starting with "Return to Tomorrow". I really think after this episode, Gene Roddenberry decided "Let's do more like that!" but the other surrounding scripts were already in development, so he had to wait until next season to really be able to get that going.
"Return to Tomorrow"
"Return to Tomorrow" was written by John T. Dugan and was re-written by Gene Roddenberry.
Memory Alpha link. You can see it most evidently in how Sargon and Thalassa's marriage and how Sargon (The Kirk of his world) is married to Thalassa, Gene's dream woman: smart and attractive at the same time. And in Sargon's warning to Kirk that his people survived their own version of a primitive nuclear age just like Earth did but there was another Crisis that all civilizations must face t
hat the Federation hasn't faced yet. Advancing to the point of thinking of yourself as Gods. Which Gene Roddenberry seemed to view as an end to civilization. Maybe because beings powerful enough to destroy everything destroyed each other. I don't know, that's open speculation on my part. But you have, in Sargon's people, a warning to Humanity of what their future might be like if they're not careful.
The story was pitched during Coon's time, then Roddenberry and Lucas did heavy revisions. John Dugan
wanted Sargon and Thelasa to continue to exist as spirits after they died. But Gene Roddenberry was against the concept of spirits or afterlife, while Dugan was deeply religious. He didn't like that Sargon and Thelasa went into oblivion so he went by his pen name, John Kingsbridge, instead. This feels like an episode Gene Roddenberry really gravitated towards, so it gradually became more
his episode. Dugan must've
hated when Gene Roddenberry added in the line "We dared think ourselves as Gods" as if Gods were a bad thing.
Joe Penvey was slated to direct this episode but he quit the series after the actors became too uncontrollable after Gene L. Coon left. Maybe because -- as someone with such a sense of humor -- Coon knew how to deal with actors being actors who were goofing off and other people didn't know how to deal with them as well, so the actors became even worse. Ralph Senesky directed this episode instead. This might've been the point where he started wanting to add more of his own touch. And one of those touches was immediately noticeable in the back-lighting. The transporter room has a purple back-light in "Return to Tomorrow" and then later, in the third season, its walls on that set are permanently painted purple. In the briefing room, the greens in the back-lighting
really pop out. Gone is using the color to highlight. They flood the walls with color and they want to give each set its own tone and feel. They're customizing the ship more with the lighting.
George Duning composed the soundtrack for this episode. He also provided original music for: "Metamorphosis" (S2), "Patterns of Force" (S2), "And the Children Shall Lead" (S3), "Is There In Truth No Beauty?" (S3), and "The Empath" (S3). "Metamorphosis" sounds a lot more emotional, romantic, and intense than a lot of other S2 episodes. "By Another Other Name" feels the same way, and adds wonder to it. All of the third season episodes that Duning composed really feel like the Core Season 3 Music. He wants you to
feel the music. It conveys a lot of mood that dialogue can't. It feels a lot more serious but also ethereal and has a weight to it.
"Patterns of Force"
Next episode I'm watching is "Patterns of Force". This was originally going to be a first season episode called "Tomorrow the Universe". (
Memory Alpha link). John Meredyth Lucas wrote a different version in the second season, which was used instead. It has a lot of stock second season music, so George Duning didn't provide that much music. There's a good combination of S1 and S2 music. And this is another one of those Parallel Earth stories with the character of John Gill recreating Nazi Germany. And there's a ton of location shooting. Then you have the end of the episode, with Spock and McCoy arguing about the history of mankind, and Kirk lightheartedly interrupting with a joke and the end. So this episode is as far from the third season as you can get. In fact, I'd even say this feels more like a late first season episode.
Taking a break there.
