Honestly, if you missed the boat on the Masters of Sex TV show when it first aired on Showtime, I get it. The marketing was... well, it was exactly what you’d expect from a premium cable show about sex researchers in the 1950s. Lots of lace, lots of suggestive gazes, and a title that practically begged for a "late-night" reputation. But here’s the thing: it wasn't that. Not really.
It was actually a brutal, clinical, and sometimes heartbreaking look at how two people—William Masters and Virginia Johnson—completely upended how we understand the human body while their own lives were a total mess. It’s one of the most underrated dramas of the last decade. Michael Sheen and Lizzy Caplan didn't just play roles; they inhabited these real-life figures with a kind of desperate intensity that makes modern "prestige" TV look a bit soft.
The Real Story Behind the Masters of Sex TV Show
A lot of people think the show is historical fiction in the "loose" sense. It’s not. It’s based on Thomas Maier’s biography, Masters of Sex: The Life and Times of William Masters and Virginia Johnson, the Couple Who Taught America How to Love. Most of the bizarre stuff? It actually happened.
Bill Masters was a renowned fertility specialist in St. Louis. He was cold. He was precise. He was, by many accounts, a bit of a nightmare to work for. Then came Virginia Johnson. She wasn't a doctor. She didn't even have a degree when she started. She was a twice-divorced nightclub singer looking for a job to support her kids.
What the Masters of Sex TV show captures so well is the power shift. In the 1950s, women weren't supposed to know anything about their own anatomy, let alone talk about it in a lab setting. Virginia changed that. She brought the "human" to Bill’s "science." Without her, the research would have stayed stuck in a cold, sterile basement. With her, it became a revolution.
The show dives deep into their actual methodology, which was—to put it mildly—controversial. They recruited prostitutes initially because nobody else would sign up to have their vitals monitored during intimacy. They used a "polygraph-like" machine to measure physical responses. They even used a clear, medical-grade device colloquially known as "Ulysses" to see what was happening internally. It sounds like sci-fi, but it was 1957.
Why Michael Sheen Was the Only Choice for Bill
Sheen’s portrayal of Bill Masters is a masterclass in repression. He plays Bill like a tea kettle that’s about to whistle but never quite does. You see him struggling with his own "maleness" and his inability to connect with his wife, Libby (played by the incredible Caitlin Fitzgerald), while he spends his days watching strangers have sex for "science."
It's uncomfortable. It’s supposed to be.

The show doesn't shy away from Bill’s flaws. He was manipulative. He was often cruel. But the writing makes you understand why. He grew up with an abusive father and a mother who stayed silent, and that trauma bled into every sensor he attached to a patient's skin.
Virginia Johnson and the Myth of the "Assistant"
Lizzy Caplan's Virginia is the heart of the show. If you've only seen her in Mean Girls or Party Down, this will blow your mind. She’s navigating a world where she has to be ten times smarter than the men in the room just to be allowed to sit at the table.
One of the best things the Masters of Sex TV show did was explore Virginia’s struggle with motherhood versus career. It wasn't the sanitized, "I can have it all" version of the 50s we see in sitcoms. She felt guilt. She felt ambition. She felt the sting of being judged by her neighbors while she was literally rewriting the book on female pleasure.
The show spends a lot of time on the Human Sexual Response—the book they eventually published in 1966. It was a bombshell. It proved that women were capable of multiple orgasms and that age didn't have to end a person's sex life. These seem like "no duh" facts today, but back then? It was like discovering fire.
The Supporting Cast Nobody Talks About Enough
While Bill and Gini (as he called her) were the stars, the ensemble was stacked.
Allison Janney and Beau Bridges had an arc in the first season that honestly deserved its own spin-off. Bridges played Barton Scully, the Provost of the university and Bill’s mentor, who was a closeted gay man in an era where "conversion therapy" involved literal electric shocks. Janney played his wife, Margaret, who spent decades wondering why her husband didn't want to touch her.
Their story is a gut-punch. It highlights the "shadow" side of the research. While Bill and Virginia were quantifying "normal," people like Barton were being told their entire existence was a pathology.

Is It Factually Accurate?
Mostly, yeah.
The show takes liberties with timelines, sure. Some characters are composites. But the major milestones—the move from Washington University to their own private institute, the "smell test" experiments, the tension with the medical board—those are all pulled from history.
One thing people get wrong is thinking Bill and Virginia were a great love story. The show treats them more like a mutual obsession. They were coworkers, then lovers, then a married couple, then... well, they eventually divorced in the 90s. The show captures that "us against the world" mentality that often leads to toxic codependency.
They weren't just studying sex; they were using it as a language because they didn't know how to talk to each other like normal human beings.
The Mid-Century Aesthetic
We have to talk about the costumes and the set design. It’s gorgeous. But unlike Mad Men, which feels very "Manhattan chic," Masters of Sex feels like the Midwest. It’s slightly more grounded. The labs are green and sterile. The homes are filled with heavy drapes and secrets.
The visual language of the show reinforces the themes. Bill is always framed by glass or bars. Virginia is often in motion. The contrast is sharp.
The Controversy and the Legacy
Why did it end after four seasons? Honestly, the ratings dipped, and the story got complicated as it moved into the late 60s and early 70s. The sexual revolution was happening outside their window, and the show had to figure out how these pioneers fit into a world that had suddenly caught up to them.

But looking back, the Masters of Sex TV show did something brave. It talked about the mechanics of intimacy without being pornographic. It talked about the politics of the body without being preachy.
It also didn't shy away from the darker side of the research. Masters and Johnson later claimed they could "cure" homosexuality, a dark stain on their legacy that the show began to address before it was canceled. It shows that even pioneers can be blinded by the prejudices of their time.
How to Watch and What to Look For
If you’re going to dive in, don’t binge it too fast. It’s a lot to process.
- Watch the pilot for the setup: See how Bill convinces the hospital to let him do this.
- Pay attention to the "Study Participants": The guest stars in the lab often reflect the emotional theme of the episode.
- Follow Libby Masters' journey: She starts as a "trophy wife" archetype and becomes one of the most complex characters on television.
The show is a reminder that progress isn't a straight line. It’s messy. It’s built on the backs of people who are often deeply flawed and selfish. Bill Masters wanted to be famous. Virginia Johnson wanted to be respected. Together, they changed the world, even if they couldn't quite figure out how to live in it.
Actionable Insights for Fans of the Show
If the history of the Masters of Sex TV show fascinates you, there are a few things you should do to get the full picture beyond the screen.
- Read the Maier Biography: If you want to know what was "real" and what was "Showtime," Thomas Maier’s book is the gold standard. It’s dense but incredibly well-researched.
- Look Up the Original 1966 Study: You can find summaries of Human Sexual Response online. Seeing the actual data points they collected makes the "lab scenes" in the show feel even more grounded.
- Compare with Mad Men: If you liked the social commentary of the 60s in Mad Men, watch Masters of Sex through that same lens. It’s the "clinical" version of that era’s social shift.
- Check Out "The New Sex Therapy": This was Helen Singer Kaplan’s work, which often clashed or built upon Masters and Johnson. It gives context to the competitive world of 70s psychology.
The show isn't just about what happens in the bedroom. It’s about the power dynamics of the office, the limitations of the 1950s family unit, and the price of being a pioneer. It’s smart, it’s sexy, and it’s surprisingly heartbreaking. Give it a shot. You'll never look at a lab coat—or a polygraph machine—the same way again.
Next Steps for Your Viewing: Start with Season 1, Episode 5, "Catherine." It’s widely considered one of the best hours of television from that era, focusing on the emotional weight of pregnancy and loss. It perfectly encapsulates why this show was never actually about the "sex," but about the humans having it.
