I'm baaaaack.
Hubby's off playing poker tonight, so I took y'all's advice and switched to production order.
The Corbomite Maneuver by Jerry Sohl
I only remembered the end of this episode, so the tension throughout really impressed me. About 90-95% of the action is on the bridge, which gives it a nice claustrophobic feel. The opening sets us up beautifully - Enterprise is mapping because they're "the first to reach this far." Later, it's mentioned that "star maps reveal no indication of habitable planets nearby." Kirk references their mission several times, which reminds us that we're exploring the frontier and have no idea what we'll find.
Apparently, this was the first episode to feature the "space: the final frontier" monologue. Still gives me chills.
We first see Kirk with his shirt off.

McCoy is running his quarterly physical. In ignoring the flashing red light and his comments to Kirk, it seems it's tough to get the Captain to actually take his physical. Technically, the first "I'm a doctor, not a..." jokes.
Bailey is set up right from the start as a bit out of his depth. He's nowhere near as calm and composed as everyone else on the bridge. When he tries to defend his reaction to the cube, Spock throws some shade and Sulu laughs because he knows better.
There are some really nice character moments throughout the episode between Kirk and McCoy, Kirk and Spock, and Kirk and Scotty. Kirk is very much the Center around which the action revolves, and he has some terrifically snarky lines aimed at Bailey. But Bailey's struggle is the emotional core of the story and Anthony Call gives a strong performance. BTW, he's still around. IMDB shows him doing a lot of documentary narration these days.
Were those frosted panes with colored lights behind them always in the ceiling of the bridge?
"Meters" seem *awfully* close to me... but perhaps that was the point.
I vaguely remember both the cube and the Fesarius being pretty scary to me as a little kid.
"Phaser crews" and "United Earth ship Enterprise" - wow. I sometimes forget that these things were still in flux for a bit.
Kirk has issues with salad. And his weight.

I love how Rand is respectful but firm.
I have often wondered if those earpieces were uncomfortable. Also, those red edges on the consoles are where you grab on!
Bailey's freakout makes sense in context - they were trapped for 18+ hours by the cube, McCoy mentioned everyone being exhausted and his concern for Bailey, all systems are dead, and a creepy (but kinda obviously a puppet) alien is going to destroy them. BUT... everyone else is doing their jobs. So McCoy was probably right.
I loved watching the light bulb come on over Kirk's head. Poker! Given this week's episode of Discovery, I found that serendipitous. Sulu's reaction to Kirk bluffing is great.
Spock mentions his mother is an Earth woman. So we got that out of the way.
*Really* nice pause after the countdown ends and they're still alive. It's easy to see Kirk was holding his breath.
Rand brings coffee. Poker and coffee - the key to any successful Starfleet mission!
I was shocked - shocked, I say! - that Scotty didn't scream about his poor engines. Still working on that characterization.
The reactions when Kirk said they were then going to rescue the tow ship... and then this:
MCCOY: Jim, don't you think...
KIRK: What's the mission of this vessel, Doctor? To seek out and contact alien life, and an opportunity to demonstrate what our high-sounding words mean.
Scotty tells them to bend low, but McCoy still nearly bumps his head.
Then, that lovely ending. I love Kirk's face throughout that final scene. He's amused, relieved, and quite happy.
