★★★★1/2 November 10, 1966 Season 1 Episode 10
If you want to see where we are…and you missed a few…HERE is a list of the episodes in my index located at the top of my blog.
This episode was written by Jerry Sohl and Gene Roddenberry
This was a really good episode. It’s a very dramatic and suspenseful episode. Kirk is seen as a commander worthy of the title as this episode shows his skills quite well. The Enterprise wanders into a part of space where they are warned to turn back and proceed no further…but that is not part of the 5-year mission.

A mysterious alien attacker claims to be able to destroy the ship with no risk of anything stopping him, and therefore grants the crew ten minutes…but they didn’t count on Captain Kirk pulling victory out of defeat. I love the look of the alien as his image gets transmitted to the Enterprise… a very handsome young man.
Kirk has a lot of boldness in this episode. He is risking the ship on a bluff but he didn’t have many options at that point. I have to say, the most disturbing thing to me was the episode’s final reveal of Balok. His appearance and the ship’s interior design, mixed with the incongruous voice really had an uncomforting effect. The episode offers a good look at the political climate of the Cold War.
The ending of this episode will throw you. You will not see it coming. I watched this one for the first time in years a few weeks ago…and yes I completely forgot about the ending. Great episode.
From IMDB
Although the script instructed Leonard Nimoy to emote a fearful reaction upon his first sight of Big Balok, director Joseph Sargent suggested to Nimoy that he ignore what the script called for and instead simply react with the single word “Fascinating.” The suggestion of this response helped refine the Spock character and provide him with a now-legendary catchphrase.
McCoy says “What am I, a doctor or a moon shuttle conductor?” which can be considered the first of the “doctor not a” quotes. In later days, the quote would have been phrased “I’m a doctor, not a moon shuttle conductor!”
James Doohan’s wartime injury to his right hand (incurred at Normandy on D-Day) is briefly visible in the conference room scene when he passes a coffee thermos. Generally this was carefully hidden off-camera, but it can also be seen when he’s holding a phaser in Star Trek: Catspaw (1967), as he carries a large bundle of tribbles in Star Trek: The Trouble with Tribbles (1967), as he reverses the probe polarity in Star Trek: That Which Survives (1969) and very briefly in freeze-frame when he’s reaching into the box to restrain the evil dog in Star Trek: The Enemy Within (1966).
This episode was originally scheduled to air much earlier than it did, but the large amount of visual effects took several months to complete. The producers had to delay the planned airdate twice, before eventually broadcasting it as the tenth episode of the season.
Both in terms of its order on the production schedule, and its order of televised broadcast, this episode marks the very first time that the Enterprise fires its phasers. The actual burst that the ship fires at the warning buoy is unique to this episode.
Summary
In a section of unexplored space, the Enterprise comes across a marker of sorts that will not let it pass. They destroy the marker and move on but soon find themselves in conflict with an unknown alien who accuses them of trespassing and tells them they have only 10 minutes to live. Kirk decides it’s time to play a little poker and literally bluff his way out of the situation by telling the alien that the Enterprise has a device on board that will destroy the alien as well as the Enterprise. The bluff works but the alien turns out to be something quite unexpected.
