This episode is another example of why the original Star Trek is and remains the gold standard.

“I make no deals for control of this ship sir” This was what made TOS great, we regularly see demonstrations of confident principle

The ending of this episode is just so sad. Their entire planet has been destroyed by their hatred. They both beam to the surface to continue their fighting. Uhura asks the captain. "Do you think hate is all they ever had?" Kirk responds, "No. but that is all they have left."

Will Riker was a master at bluffing in poker. Captain Kirk was a master at bluffing in war.

People forget that Star Trek was one of the first TV shows that attacked all types of social injustices practices. The prejudice of racism because of skin color. Two from the same planet that looks identical unless you really pay attention to their faces which actually have the color on the opposite sides. Beautiful! How simple Star Trek reduced racism to silliness.

One of the very best episodes, and Frank Gorshin was outstanding.

They used the exact same code sequence in Star Trek III. Pretty neat how it tied together.

He didn’t over-act, this was absolutely priceless 🙌🏼

One of the best episodes ever in Star Trek history. Very relevant, even today.

As a teenager I recall the profound reaction I had to this episode when realizing along with Kirk, their only difference was the pigmentation\colorization on either side of the face. I too assumed they were the same. Any Martian or alien who would visit earth would wonder what all the fighting we humans do, is about. The profundity of my realization on that day, has not left me since then. We humans are a family! BIG DEAL if you are white, black, brown green or pink! Big Deal! You are my brothers and sisters! Now, let's get on with life and fight just a little less!

This show's stories were so far ahead it's time. Holds up well 60 years later.

I love how the rest of the crew relaxed AFTER Kirk gave the final code, like they figured there was a reasonable chance of him saying "Ah screw it, computer. Full send."

Star Trek's third season deserves a lot more credit than it often gets, and this scene is a great example of why.

What is really impressive is the stoicism of the bridge crew, during what (for all they knew) might have been the final seconds of their lives, if Bele hadn't cracked.

This episode is great, it lets us see one of Shatner's great over acting scenes when Bele leaves the bridge. He just utters his name "Bele" then the next scene cuts to Shatner shaking his head saying they have no where to run. Classic Kirk....

This episode stuck with me long after it ended, and that was decades ago. Clearly one of the very best star trek episodes.

This episode was ahead of it's time. Love how Lokai always begs for help from total strangers. :)

MINE is the FINAL COMMAND...EPIC!

I met a very engaging Frank Gorshin and told him, aside from my Batman gushing comments, that I saw a blooper reel of him doing Cagney in the transporter chamber. He laughed and told me he didn't think they were filming when he did that.

"You can use your will to drag this ship to Cheron, but I command the computer. MINE is the final command."

Frank Gorshin was born to play a bad guy Star Trek, Get Christie Love, Charlie's Angels, but he will forever be known as The Riddler in the 60's Version of Batman God Rest His Soul

WOW! Even sitting here with my cup of tea I was holding my breath, Bloody Hell that was a great show.

"I make no deals for control of this ship." Boss!

That show was a direct black/white comment on race relations. Both originated from a similar genetic stock. But, (down the line) they split into reverse genetic coding. The final scene is both fighting (forever) in space. The Enterprise continued on its mission. Yet, a multi-cultural crew continued on their mission of exploration (not fighting against each other - but helping each other to perform a single duty). That was the point of this episode.

Kirk is the man . Best star ships captain ever .

Frank Gorshin was excellent as Bele, the ingratiating Commissioner from Cheron. He met his match when he tried to outmaneuver Kirk at every possible turn. Only after he forced his willpower over the Enterprise to reach Cheron did Bele (and Lokai) realize their 50,000 racial war totally destroyed the inhabitants. It was a great episode about the stupidity and destructiveness of racism.

Frank Gorshin was a great 60's villain God Bless Him. Rest In Peace.

I think that casting them as the same race with different colours on each side was kind of the point.

I so enjoyed this show as a teenager. I was the only one in my group of friends who liked it. None of them are my friends anymore...

"...and at Warp 10, we're goin' nowhere mighty fast!" LOL

Frank Gorshin was a once in a million talent. Love this episode because of him.

The destruction of the Enterprise in The Search For Spock was saddening.

This episode was the only one that my guardians let me watch as a child..I fell in love with Star Trek then!!!

Great work by Gorshin, one of Trek's great all-time scenery chewers.

Fantastic clip.The whole episode was a powerful & relevent message against racism in the late 1960's and perhaps even more so today 2017.

And at warp 10 were going nowhere mighty fast!

I was 10 when I saw this scene for the first time. It affected me for months-my mom even took me to a psychologist. He was ahead of his time; he diagnosed me with autism and a photographic, not eidetic, memory. I can still picture our black-and-white television with that scene playing to this day. It also helped shape my mind to learn mindful balance in good, bad, and terrible situations; from family conflicts between my seven siblings to study discipline through grad school, during the time one of my nephews took his life to being a responsible dad, this scene has been with me even now. All the other scenes pale in comparison in my mind.

Brilliant episode, and one of Frank "Riddler" Gorshin's great performances.

Nurse Chapel, thank you again for the voice of the computer. I guess being the beautiful wife that you were to Gene Roddenberry, you had something to say in this episode. The computer words that you hear in this episode were the same as the person who played No. 1 in the original pilot series at her best as Captain Pike's first officer. The rest is Star Trek history. And if you don't know what I'm talking about, you don't know your Star Trek lore.

Kirk had balls of steel

The password is "123"? They might as well go with "password"

When the computer rules your life; Who controls the computer controls your life.

00:51 Great reaction by Scotty. After this he went to his quarters and had a few belts of Saurian Brandy.

Gorshin was highly underrated as an actor. I remember him on Carson doing impressions of Kirk Douglas. Classic

The Kirkmiester plays a mean hand of poker, don't he?

I've been thinking of what to put down. This single episode gave me a glimpse of what Gene Roddenberry's vision was about.

I like how the computer is intelligent enough to halt the countdown when Bele says "I agree" like as though the Enterprise realized it was a bluff. It certainly never really showed that ability in the rest of the series it more just analyzed data that was given and relayed information. Unless perhaps a scenario such as this was implanted into the computer beforehand so Kirk could use self destruct as a tool. I doubt that though.

Imagine u were a redshirt who had just come within 5 seconds of a self destruct order with no explanation from kirk and then hes just like “alright everyone back to normal”

Kirk is the man!

The entire bridge crew "surely the Captain won't kill all of us just to make a point.... Right... RIGHT CAPTAIN!?

And at warp 10 we're going no where mighty fast lol. Always a great line

Kirk is a brave and clever captain!My favorite!

I think he would have really blown up the ship. And the crew was going right along with the captain on the destruction computer program.

where the person who invented black & white cookies got his inspiration...............

This is the first time I can recall any on-screen TV usage of the word "disgusting" as a reference to racial prejudice. Over the many years since then, I've heard many people refer to the word "disgusting" when a derogatory racial reference was made. But this is the first time I've ever heard it on tV. See time sequence 4:00.

"The need to resort to violence has long since past?!".....Every other episode shows fist fights on the bridge! 😂😂😂

Back when I was in the Army, I once did my camo face paint like these guys as a joke. Good memory haha! Our lieutenant was not amused.

"The need for violence has long since past!" I miss the days when Star Trek served a purpose.

Damn those first 60 seconds were gold. I'd have loved to see this when it first aired.

Kirk isn’t having any of that shit! Haha what a badass.

The destruxt sequence was re-used, word for word in Star Trek III; The Search For Spock.

One of the few superior episodes from S3 and the entire series, in my humble opinion.

The facial black/white white/black makeup on each actor....DOPE!!!....👍👍👍

I just KNEW Kirk would defeat the Riddler.....

I love how the computer is making the sounds of a type writer.

0:13-0:21The most powerful words ever stated!!

Such power those two exercised. Yet, somehow were unable to use it upon each other.

They should have included the whole destruct procedure. The rising tension makes for a great scene.

the black and white cookie aliens! they always reminded me of the those big half black and half white cookies you could get at a bakery!

Kirk will always be the best captain of the enterprise.

"Code 123? That's the same code I use on my luggage!!!"......

Real excellent series, real excellent after 6 decades ....remember it from my childhood❤

RIDDLER!!!!!!!!!!!!!

of course the most unthinkable password in the universe, "123"!!!!

Tense...Very tense. When I first saw this I sweated like a prize fighter-!

FYI: Star Trek Season 3 Episode 15 “Let That be Your Last Battlefield” 1st broadcast on 01/10/69

In many ways, I think this is the best episode

That's what happens when you fall asleep with one side facing a tanning lamp. How embarrassing!

I always considered "The Riddler" to be a comedic villian. I was impressed with Frank Gorshin's ability to play a serious one.

Frank Gorshin was excellent in whatever part he played. He was also a great comedian with flawless delivery.

Grief that black paint looked sweaty and thick !!

Frank Gorshin, who ended up playing the Riddler played Bele here, he was an Army Air Forces veteran of World War II and was an impressionist...

"Code 123, genius. How could I have ever thought of that."

Ultimate bluff, the carbonite maneuver.

Computer "About to destruct 4 3 2 1.... Um, what comes after 1?"

"Fascinating! Two irrevocably, hostile humanoids."

"The need to resort to violence has long since passed and will not be tolerated aboard this ship." From Kirk?!? Riiiight. File that with the Prime Directive and the "we don't use money" bit.

I loved Frank Gorshin in this role. Up until then, I had only known him as a very good impressionist and comic. With the right role he could have won an Oscar.

Warp factor 10 was set as an unattainable maximum of a theoretical infinite speed, at which an object would occupy all points in the universe simultaneously (according to the new scale, reaching or exceeding warp 10 required an infinite amount of energy)

Despite one being the slave and one being the master, they were both as disgusting as each other. I think that's the most important point. You can bang on all you like about being oppressed, but no one will care unless you act like the better person. It's difficult, but it's what seperates you from your oppressors, the ability to do better, to be better.

I love Star Trek for such moments. despite the "reality" of it, in this show Kirk commands the computer so he commands the ship, not the other way around! so long as The Compter and the Starship answer only to the Captain and his crew, all is well! but the opposite is probably true in real life. Bael would be saving us if he destroyed a ship with an uppity computer.

It's a good think Kirk didn't get a sneeze coming on then.

Wow, testes of neutronium there...

And now a word from our sponsor ...Price Line Dot Com...

Haven't seen this since I was a kid watching it during the initial broadcast.

“We are going nowhere really fast” hahahahaha

One of the best episodes.

The U.S.S. Enterprise didn't self-destruct in this Star Trek: The Original Series episode until Star Trek III: The Search for Spock (1984).

That's the same combination I've got on my luggage!

One of my all time favorite episode of Star Trek
