Honestly, it shouldn't have worked.
When Desilu Productions pushed Star Trek onto NBC’s schedule in 1966, the "original Star Trek crew" was basically a ragtag collection of character actors and a Shakespearean lead who took himself very seriously. They had a tiny budget. They had cardboard sets. Most critics at the time thought the show was kind of a joke, or at least just another "Wagon Train to the Stars" that would be forgotten by the next pilot season.
But they were wrong. Totally wrong.
What happened on that bridge—the chemistry between William Shatner, Leonard Nimoy, and DeForest Kelley—became the blueprint for every ensemble drama that followed. It wasn't just about space exploration or phasers. It was about a very specific, three-way psychological balance that most modern reboots try to copy but usually fail to nail.
The Power Trio: Logic, Passion, and the Guy in the Middle
You’ve probably heard of the "Freudian Trio" theory. It’s the idea that Kirk, Spock, and McCoy represented the three parts of the human psyche. Spock was the Ego (logic), McCoy was the Id (emotion), and Kirk was the Super-ego trying to make a choice between them.

It sounds academic. In practice, it was just great TV.
Leonard Nimoy didn't even want to be Spock at first. He was worried about the ears. He thought he'd look ridiculous. But Nimoy brought a weird, quiet dignity to the role that forced everyone else to level up. When Spock would drop a line about logic, DeForest Kelley’s Dr. McCoy would jump down his throat with a "Dammit, Jim!" or a complaint about "green blood."
McCoy was the heart. He was a country doctor who just happened to be in space. While Spock looked at a dying alien as a biological curiosity, McCoy saw a patient. Kirk stood between them.
William Shatner gets a lot of flak for his "acting style" these days. People love to parody the pauses. But if you actually watch those early episodes—like "The City on the Edge of Forever"—Shatner’s Kirk is incredibly grounded. He had to be the guy who could out-punch a Gorn but also weep over a woman he had to let die to save the future. Without that specific dynamic, the show would have just been a dry procedural about map-making in the Beta Quadrant.
The Supporting Players Who Refused to Be Background Noise
The rest of the original Star Trek crew—Nichelle Nichols, James Doohan, George Takei, and Walter Koenig—weren't originally supposed to be the icons they became. In the first season, Uhura and Sulu were often just "the people at the consoles."
But the 1960s were a mess. Civil rights, the Vietnam War, and the Cold War were tearing the U.S. apart. And here was Gene Roddenberry, a guy with a lot of flaws but a big vision, putting a Black woman, a Japanese man, and eventually a Russian (Chekov) on the bridge of a flagship.
It was radical.
Nichelle Nichols famously wanted to quit after the first season to pursue Broadway. She actually had her resignation letter ready. Then she met Dr. Martin Luther King Jr. at a NAACP fundraiser. He told her she couldn't leave. He told her that for the first time, people were seeing a person of color in a position of authority, respected as an equal, and not just playing a maid or a caricature.
She stayed.
James Doohan, a veteran of Juno Beach on D-Day who actually lost a finger during the war (watch his hands closely in old episodes; he hides it well), gave Scotty that iconic Scottish accent because he thought Scots were the best engineers in history. George Takei brought a sense of physical prowess to Sulu that went against every Hollywood stereotype of Asian men at the time.
These weren't just actors. They were symbols.
The Reality of the Set: Not Always a Happy Family
We have to be real here. It wasn't all sunshine and "Live Long and Prosper" behind the scenes.
The original Star Trek crew had major friction. It’s well-documented that George Takei and William Shatner didn't get along. Takei felt Shatner was a bit of a "line hog" who would try to take dialogue away from the supporting cast. Doohan felt the same way for years.
There was also the "Spock-mania" issue. During the first season, NBC started getting way more fan mail for Nimoy than for Shatner. For a lead actor in the 60s, that was a huge blow to the ego. Shatner reportedly struggled with the idea that his second-in-command was becoming the face of the franchise.
However, something changed when they started making the movies in the late 70s and 80s. They grew up. By the time they were filming Star Trek II: The Wrath of Khan, they realized that the "ensemble" was what the fans loved. The friction was still there, sure, but it was buried under a decade of shared history and the realization that they were all stuck in this "Trek" bubble together forever.
Why the 2009 Reboot Felt Different
When J.J. Abrams brought in Chris Pine and Zachary Quinto, they did a great job. They really did. But you can’t manufacture 1966.
The original crew was older. By the time the movies rolled around, they looked like people who had actually spent twenty years in a tin can flying through a vacuum. They had wrinkles. They had gray hair. When Kirk says "I feel old" in The Wrath of Khan, you believe him.
The modern versions are great, but they feel like athletes. The original crew felt like your slightly eccentric uncles and aunts who happened to know how to recalibrate a warp core. There’s a texture to the original performances that comes from the specific era of stage-trained acting they all came from.
The Legacy Beyond the Screen
People always talk about the technology Star Trek "invented"—cell phones, tablets, MRI machines. But the real legacy of the original Star Trek crew is social.
Take the "interracial kiss" in "Plato’s Stepchildren." It’s often cited as the first on American TV (though that’s technically debated by TV historians). Regardless, it was a massive deal. The network was terrified. They wanted to film two versions: one where they kissed and one where they didn't.
Shatner and Nichols reportedly flubbed every take of the "no kiss" version on purpose so the network would be forced to use the kiss.
That’s the kind of crew they were. They knew they were doing something that mattered.
How to Engage with the Original Crew Today
If you're looking to really understand why this specific group of people changed the world, don't just watch the Greatest Hits. Go deeper.
- Watch "The Tholian Web": It's a masterclass in how the crew functions when Kirk is missing. You see Spock and McCoy's tension reach a breaking point, and you see how much the ship relies on their mutual respect, even when they’re screaming at each other.
- Listen to the "Saturn" Audio: There are amazing behind-the-scenes recordings of the cast at various conventions in the 70s. It captures the raw energy of the fans before "Trekkie" was even a common word.
- Read "I Am Spock" and "I Am Not Spock": Leonard Nimoy’s two memoirs show the internal struggle of an actor trying to separate himself from a character, only to realize he couldn't.
- Study the 1970s Fan Campaigns: The original crew wouldn't exist without the fans. When NBC tried to cancel the show after Season 2, a massive letter-writing campaign led by Bjo Trimble saved it. It was the first time fans realized they had power over a studio.
The original Star Trek crew taught us that the future doesn't have to be dystopian. It doesn't have to be a "Mad Max" wasteland where we're all fighting over water. They showed us a future where we’ve solved our problems on Earth and decided to see what else is out there.
They weren't perfect people. They were actors with egos and complicated lives. But for 79 episodes and six movies, they were the best version of us.
If you want to dive back in, start with the remastered versions of the original series. The colors are brighter, the ship looks better, but the performances—those weird, human, brilliant performances—are exactly the same as they were on a Friday night in 1966.
