Matthew Weiner famously didn't want big stars. He wanted actors who looked like they belonged in a 1960s boardroom or a suburban kitchen in Ossining, not on a 2007 billboard. That gamble is why the Mad Men series cast remains the gold standard for television ensembles.
Honestly, it’s hard to imagine anyone else as Don Draper. Jon Hamm was a relative nobody before this. He’d been working in Hollywood for years, doing bit parts and probably wondering if he should just head back to Missouri. Then he walked in. He had that square jaw, that stillness, and a voice that sounded like expensive bourbon. But it wasn't just about Hamm. The magic of the show was how every single person on screen felt like they had a life before the cameras started rolling and a life after they stopped. It wasn’t a show about "characters." It felt like a show about people.
The Anchors: Don, Peggy, and the Art of the Long Game
Jon Hamm's portrayal of Don Draper is a masterclass in internal conflict. You’ve seen the memes, the silhouette in the chair, the cigarette smoke. But the real work happened in the eyes. Hamm played a man who was essentially an identity thief, a Korean War deserter named Dick Whitman who stole a dead man's life. That's a lot of baggage for one actor to carry through seven seasons. He didn't play Don as a hero. He played him as a deeply flawed, often cruel, but undeniably talented creative who was constantly running away from himself.
Then there’s Elisabeth Moss.
Peggy Olson’s trajectory is arguably the most important arc in the entire series. She starts as the "new girl," the mousey secretary who doesn't know how to use a typewriter. By the end, she’s a powerhouse. Moss brought a certain grit to the role that made Peggy’s rise feel earned. It wasn't a girl-power fantasy; it was a grueling, often lonely climb through a sexist corporate ladder. When she walks into McCann Erickson in the final season, wearing sunglasses and holding a box of her things while smoking a cigarette, it’s one of the most iconic moments in TV history. It worked because we saw the ten years of struggle that led to that one minute of confidence.
The Sterling Cooper Power Players
John Slattery as Roger Sterling was the show's secret weapon. He got all the best lines. Seriously, if you go back and watch, Roger’s wit is the only thing that keeps the show from being too depressing at times. Slattery played the silver-maned heir to the agency with a mixture of boredom and existential dread. He was the guy who had everything handed to him but realized none of it actually made him happy.

- Christina Hendricks (Joan Holloway): She wasn't just the office manager. She was the heart and the brains of the operation. Hendricks played Joan with such command that she effectively changed how audiences viewed power dynamics in the workplace.
- Vincent Kartheiser (Pete Campbell): Everyone hated Pete at first. He was the sniveling, entitled prep school kid. But Kartheiser’s performance made Pete one of the most complex figures on screen. By the end, you sort of found yourself rooting for him, or at least respecting his strange brand of loyalty.
- Robert Morse (Bert Cooper): A legend of the Broadway stage, Morse brought a whimsical, shoes-off eccentricity to the senior partner. His final musical number, "The Best Things in Life Are Free," was a hauntingly beautiful goodbye.
Why the Mad Men Series Cast Felt Different
Casting director Ellen Chenoweth and later Laura Schiff and Carrie Audino had a specific "look" in mind. They avoided the "TV-pretty" aesthetic of the mid-2000s. They wanted faces that looked period-accurate. This is why January Jones was so perfect as Betty Draper. She had that Grace Kelly coldness—a suburban Hitchcock blonde who was slowly suffocating under the weight of her own "perfect" life.
Jones gets a lot of flak for being "stiff," but that was the point. Betty was a woman who was taught to be a mannequin. Her rigidity was her armor. When she finally breaks, or when she’s shown in her final moments dealing with her diagnosis, you realize just how much Jones was doing with very little dialogue.
And we can’t forget the kids.
Kiernan Shipka grew up on this show. We saw Sally Draper go from a little girl playing with a plastic bag over her head (a scene that would never fly today) to a cynical, enlightened teenager who saw her father for exactly who he was. Casting a child actor who can actually keep up with Jon Hamm is a miracle. Shipka didn't just keep up; she often stole the scenes.
The "That Guy" Factor: Guest Stars and Recurring Roles
A huge part of the Mad Men series cast's success was the rotating door of incredible character actors. Think about Jared Harris as Lane Pryce. His arc is one of the most tragic in the series. The British CFO who just wanted to belong in America but was eventually undone by a forged check and his own sense of honor. Harris’s performance was so visceral that his final scene in season five still haunts fans of the show.

Then you have:
- Peyton List as Jane Siegel: The second Mrs. Sterling who represented the shift from the 50s to the 60s.
- Jessica Paré as Megan Draper: The "Zou Bisou Bisou" heard 'round the world. She brought a youthful, Canadian energy that signaled the death of the old guard.
- Ben Feldman as Michael Ginsberg: The brilliant, neurotic copywriter who eventually succumbed to the pressures of the changing world (and his own mental health).
The Business of Casting a Period Piece
The logistics were insane. Every actor had to fit the clothes. If you gained five pounds, the vintage costumes wouldn't zip. The hair and makeup team, led by Gregory Nicotero and others, worked in tandem with the actors to ensure the physical transformation was absolute. You don't just put on a suit and become Don Draper. You have to move differently. You have to hold a glass differently.
Bryan Batt, who played Sal Romano, once talked about how the costumes dictated his posture. The high-waisted trousers and the structured jackets changed how the actors sat and breathed. It was an immersive experience. This attention to detail is why the Mad Men series cast feels so authentic. They weren't actors playing dress-up; they were people inhabiting a specific era.
Misconceptions About the Cast and Their Careers
People often think that because the show was a massive critical hit, every actor became an A-list movie star immediately. That's not really how it worked. While Jon Hamm and Elisabeth Moss have had incredible careers, many of the cast members moved into prestige TV or theater.
The "curse" of being on a show this good is that you are forever associated with that character. Rich Sommer will always be Harry Crane to a certain segment of the population. Michael Gladis will always be Paul Kinsey. But that’s a testament to the writing and the performances. They created icons.

Nuance in the Background
Watch the background of any scene in the breakroom or at a party. The extras—or "atmospheric actors"—were cast with the same scrutiny as the leads. Weiner was notorious for checking the watches and hairstyles of people who were barely in the frame. If you didn't look like you lived in 1964, you weren't on the set.
This created a feedback loop. The lead actors felt like they were in a real world, which made their performances more grounded. When Don Draper walks through the office, the way the secretaries react to him isn't just "acting"; it’s a reflection of the hierarchy that was baked into the production design and the casting.
What We Can Learn from the Casting Process
The biggest takeaway from the Mad Men series cast is the value of the "ensemble." No one person was bigger than the story. Even Jon Hamm, as the lead, often took a backseat to let Peggy or Joan or even a character like Stan Rizzo (played with great beard-energy by Jay R. Ferguson) have their moment.
It teaches us that in any creative endeavor, the "fit" is more important than the "fame." If they had cast a massive movie star as Don Draper, the show might have become a vehicle for that star's ego. Instead, it became a tapestry of human failure and ambition.
Actionable Insights for Fans and Creators
If you’re looking to dive deeper into the world of these actors or if you're a creator looking to replicate this kind of success, consider these steps:
- Watch the "Actors Roundtables": Look for the early Hollywood Reporter roundtables featuring Jon Hamm and Elisabeth Moss. They talk candidly about the fear of the show being canceled in the early days.
- Track the "Mad Men" to "Prestige TV" pipeline: Notice how many actors from this show popped up in later hits like The Handmaid’s Tale, Fargo, or Brave New World. It’s a masterclass in how casting directors look for talent.
- Study the physical acting: Re-watch a scene on mute. Look at how Christina Hendricks uses her body to command a room without saying a word. Look at how John Slattery uses a cigarette as a prop for his comedic timing.
- Read "The Fashion File" by Janie Bryant: The show’s costume designer explains how she used the cast's physical attributes to tell the story of their characters’ social standing.
The legacy of the Mad Men series cast isn't just the awards they won. It's the fact that, even a decade after the finale, we still talk about these characters like they’re people we actually knew. We worry about Sally. We wonder if Peggy ever became Creative Director at a major firm. We hope Roger found some semblance of peace. That’s not just good writing—that’s the power of the right person in the right role at exactly the right time.
The show proved that you don't need explosions or high-concept sci-fi hooks if you have a group of actors who can make a conversation over a glass of rye feel like a life-or-death situation. It remains a blueprint for every prestige drama that has followed.
