Webbed hands. Yellow swim trunks. A weird, undulating swimming style that looked more like a dolphin with a backache than an Olympic athlete. If you grew up in the late 1970s, the Man from Atlantis wasn't just another TV show; it was a bizarre, short-lived fever dream that somehow changed how we look at the ocean. Honestly, it's easy to dismiss it now as a campy relic of the disco era. But looking back, there’s a lot more going on under the surface than just Patrick Duffy’s impressive lung capacity.
The show premiered as a series of four TV movies in early 1977 before NBC greenlit a full season. It followed Mark Harris, a man found washed up on a beach who happens to be the last survivor of the legendary lost city. He can breathe underwater. He has superhuman strength. He can withstand the crushing pressure of the deep trenches. Basically, he’s Aquaman without the orange shirt or the ability to talk to tuna.
The Patrick Duffy Effect and the Birth of a Cult Classic
Before he was Bobby Ewing on Dallas, Patrick Duffy was the face of the Man from Atlantis. It’s hard to overstate how much he committed to the bit. He didn't just "swim." He developed a specific, rhythmic body movement that helped him glide through the water without using his hands. It looked cool, sure, but it was also incredibly taxing to film. He spent hours in the water, often until his eyes were bloodshot from the chlorine and his skin was prune-like.
NBC saw a hit. The initial movies pulled in massive ratings. People were obsessed with the mystery of Mark Harris. Who was he? Why did he have those translucent webs between his fingers? The show felt grounded in a way that Star Trek didn't—it was about our world, or at least the 71% of it we hadn't explored yet.
Then things got weird.
When the weekly series actually started in the fall of 1977, the tone shifted. It moved away from the grounded mystery of the pilot movies and dove headfirst into "villain of the week" territory. We got Mr. Schubert, played by the legendary Victor Buono. He was a classic megalomaniac with a submarine and a flair for the dramatic. While Buono was fantastic, the show started feeling less like a deep-sea exploration and more like a low-budget superhero flick.
Why the ratings tanked
It didn't last. The show was canceled after just 13 episodes of its first full season. Why? Well, it was expensive. Filming underwater is a logistical nightmare even today; in 1977, it was a budget-killer. Plus, the competition was stiff. The show was fighting for airtime against heavy hitters, and the audience eventually drifted away.

But here’s the kicker: even though it died a quick death in the U.S., it became a massive phenomenon internationally. In China, it was the first American TV series ever aired after the Cultural Revolution. To an entire generation of Chinese viewers, Mark Harris is basically the most famous American hero. That’s a legacy most "successful" shows would kill for.
Science, Scifi, and the Foundation of Undersea Tech
Even though the Man from Atlantis was fiction, it leaned heavily into the "Cetacean Research Institute" (CRI). This was the organization that "owned" (or at least housed) Mark Harris. Led by Dr. Elizabeth Merrill, played by Belinda Montgomery, the CRI used the Cetacean, a high-tech submersible that actually looked pretty sleek for the time.
The show tapped into the zeitgeist of the 1970s oceanography boom. This was the era of Jacques Cousteau. People were genuinely interested in the "silent world."
- Pressure Resistance: The show tried to explain Mark's ability to dive deep by discussing internal pressure equalization. It wasn't always scientifically sound, but it introduced kids to the concept of the "bends" and atmospheric pressure.
- The Power of the Ocean: Unlike many shows that treated the ocean as just a backdrop, this one treated the water as its own character. It was dangerous. It was vast.
- Genetic Anomalies: The webs between Mark's fingers and his light-sensitive eyes were an early pop-culture nod to the idea of human evolution or aquatic adaptation.
The swimming style that changed everything
You can't talk about the Man from Atlantis without mentioning the "dolphin kick." Before this show, most people just did the crawl or the breaststroke. Duffy’s undulation was actually a precursor to what we now see in professional swimming. Swimmers today use the underwater dolphin kick off the start and every turn because it is, scientifically, the fastest way to move through water.
While Patrick Duffy didn't "invent" the physics of it, he certainly popularized the visual. It looked alien in 1977. Today, it's how you win an Olympic gold medal.
The Legacy of Mark Harris
So, why should we care about a show that barely made it through one season?
First off, it paved the way for more ambitious sci-fi on television. It proved that you could have a lead character with a physical "power" that wasn't just flying or super-strength. It was environmental. Mark Harris was vulnerable. He needed to get back to the water frequently or he’d literally die. This created a built-in ticking clock for every episode.
Secondly, the production design was actually quite ambitious. The Cetacean submarine set was elaborate. The underwater photography, led by experts like Lamar Boren, was top-tier for the 1970s. Boren had worked on Thunderball and Sea Hunt, and he brought a cinematic quality to a TV budget.
Misconceptions about the "Last Survivor"
Many people remember Mark Harris as being from Atlantis. But the show actually kept that vague for a long time. He was found and assumed to be from there. The mystery of his origin was supposed to be the long-running arc of the series, but since the show was canceled, we never really got the full payoff.
Patrick Duffy eventually wrote a novel in 2016 to finally tell the story he wanted to tell. He clearly still cares about the character. In his book, he leans much harder into the mythology and the "how" of Mark’s existence. It’s a rare case of an actor being so invested in a canceled role that he finishes the story himself decades later.
What Most People Get Wrong About the Show
A lot of folks lump Man from Atlantis in with The Six Million Dollar Man or Wonder Woman. While there are similarities, it was much more contemplative. Mark Harris wasn't a soldier. He wasn't a crime fighter. He was a curious explorer who just happened to have gills (sort of).
The show often touched on ecological themes. It warned against the exploitation of the seabed. It looked at how humanity's greed could destroy the very things that kept us alive. It was "green" before that was even a mainstream concept.
- The Costume: People remember him in a wetsuit. He almost never wore one. He wore those iconic yellow trunks. Why? Because a man from the deep wouldn't need protection from the water.
- The Tone: It wasn't all action. There were long sequences of just... swimming. It was meant to be peaceful, almost meditative.
- The Villains: While Mr. Schubert was the main baddie, many of the "monsters" Mark encountered were just misunderstood creatures or products of human interference.
Actionable Insights for Fans and Collectors
If you're looking to dive back into this world, you have a few options that don't involve scouring shady VHS sites.
- The DVD Sets: Warner Archive released the complete series and the pilot movies. These are the best quality you'll find, as they’ve been cleaned up significantly from the original broadcast tapes.
- The Novel: Check out Patrick Duffy’s book, Man from Atlantis. It’s a deeper, more mature take on the lore and fills in the gaps the TV show left behind.
- The Swimming Technique: If you’re a swimmer, look up "monofin training." It’s the real-world version of Mark Harris’s swim style. It’s an incredible core workout and surprisingly fast.
- The Comics: Marvel actually did a short run of Man from Atlantis comics in the late 70s. They are great pieces of nostalgia and usually affordable at local comic shops or on eBay.
The Man from Atlantis might be a bit cheesy by 2026 standards, but its heart was in the right place. It encouraged us to look at the ocean not as a resource to be mined, but as a home to be respected. It’s a weird, wet piece of TV history that deserves a little more respect than it usually gets. If you can get past the 70s hair and the occasional giant jellyfish puppet, there's a really charming story there about a man just trying to find where he belongs.
To truly appreciate the show's impact, watch the original pilot movie first. It holds up much better than the later episodes and captures the sense of wonder that made the show a hit in the first place. Once you’ve done that, you’ll understand why people in Beijing and Boise alike were once obsessed with the man in the yellow trunks.
