It started with a hospital bed.
Andrew Lincoln woke up, stumbled into a hallway full of corpses, and changed television forever. Looking back at those six episodes from 2010, it’s wild to see how small it all felt. Frank Darabont, the guy who gave us The Shawshank Redemption, was at the helm, and he hand-picked a group of people who weren't really "A-list" superstars yet. They were character actors. They were gritty. They looked like they actually belonged in a humid, gross, post-apocalyptic Atlanta.
The actors of walking dead season 1 didn't just play roles; they set a blueprint for what prestige horror could look like on a cable budget.
Honestly, the casting was a bit of a gamble. You had a British guy playing a Kentucky sheriff, a relatively unknown Jon Bernthal as the ticking time bomb, and a bunch of faces you’d maybe seen in bit parts on Law & Order. But that lack of massive ego is exactly why it worked. You believed they were scared. You believed they were tired. You believed that Shane was slowly losing his mind while Rick was trying to find his soul.
The Rick Grimes effect and Andrew Lincoln's massive pivot
When Andrew Lincoln got the part, most people in the UK knew him from Love Actually or the series Teachers. He was the "nice guy." Then he grows this scruffy beard, adopts a Southern drawl that became the stuff of a thousand "CORAL!" memes, and becomes the moral compass of the end of the world.
Lincoln’s performance in that first season is subtle. If you rewatch the pilot, "Days Gone Bye," he barely speaks for the first twenty minutes. It’s all physical acting. He has to convey the sheer confusion of a man who missed the end of the world while in a coma. Most actors would overplay the "Where am I?" trope, but Lincoln plays it with this hollow-eyed shock that feels painfully real.
What’s interesting is how his departure years later almost broke the show. It proves that the foundation laid by the season 1 cast wasn't just about the zombies—it was about the weight of his leadership.
Jon Bernthal was always too big for a small screen
Can we talk about Shane?

Jon Bernthal is probably the biggest "success story" to come out of the original group in terms of raw intensity. Before he was The Punisher or stealing scenes in The Bear and Wolf of Wall Street, he was Shane Walsh. In the comics, Shane dies pretty fast. Like, blink-and-you-miss-it fast. But the chemistry between Bernthal and Lincoln was so electric that the showrunners kept him around just to see the friction.
Bernthal has this way of moving. He’s restless. Even when he’s standing still, he looks like he’s about to punch a wall or sprint a mile. In season 1, he had to play the "best friend who stole the wife" without becoming a total cartoon villain. You almost felt for him. Sorta. He thought Rick was dead! He stepped up. And then the "dead" guy walks back into camp and takes everything back. That’s a recipe for a psychological breakdown, and Bernthal ate that role for breakfast.
The Atlanta camp: A masterclass in "Hey, I know that guy!"
The supporting cast was a weird, beautiful mix of talent that Frank Darabont had worked with before.
- Laurie Holden (Andrea): She had worked with Darabont on The Majestic. Her character in season 1 is vastly different from the hardened warrior she becomes later. She’s grieving. She’s terrified.
- Jeffrey DeMunn (Dale): The moral backbone in the bucket hat. DeMunn is another Darabont regular (The Green Mile, The Mist). He brought a theatrical dignity to a show about rotting flesh.
- Steven Yeun (Glenn): This was basically his first big break. He was a pizza delivery boy who saved the protagonist. Yeun brought the only sense of levity to the show. Without him, the first season might have been too bleak to survive. Watching him evolve from the "kid" to an Academy Award-nominated lead in Minari is one of the coolest arcs in Hollywood history.
Then you have Sarah Wayne Callies as Lori. Man, the internet was mean to Lori. But if you actually watch her performance in season 1, she’s playing a woman who is processing trauma in real-time. She thinks her husband is dead, she’s protecting a kid, and she’s sleeping with the only man who kept her alive. It’s messy. It’s human.
Melissa McBride and the long game
If you watched the first season as it aired, you probably didn't think Carol Peletier would be the last one standing.
Melissa McBride’s Carol in season 1 was a victim. She was quiet, mousy, and trapped in an abusive marriage with Ed (who, let's be honest, we all hated). There was no hint of the "cookie-baking assassin" she would become. The sheer range McBride showed over the next decade is wild, but it started with those small, trembling moments in the Atlanta outskirts.
The actors of walking dead season 1 had to do a lot with very little. They weren't fighting massive CGI hordes yet. They were sitting around a campfire talking about watches and lost relatives.

Why the casting of Norman Reedus changed the script
Here is a fun fact: Daryl Dixon doesn't exist in the comics.
Norman Reedus originally auditioned for the role of Merle (which went to Michael Rooker). The casting directors liked Reedus so much that they literally created Daryl for him. Think about that. The most iconic character in the entire franchise, the guy with the crossbow, was an afterthought.
In season 1, Daryl is a jerk. He’s racist, he’s loud, and he’s angry. But Reedus played him with this underlying vulnerability—this "kinda like a kicked dog" energy—that made fans fall in love. By the time they reached the CDC at the end of the season, Daryl was already becoming the breakout star.
The CDC and the ending that almost wasn't
Noah Emmerich played Dr. Edwin Jenner in the season 1 finale. It’s a bottle episode, basically. They get to the CDC, they think they’re saved, and then they realize the building is going to self-destruct.
This was a turning point. It shifted the show from "surviving the woods" to "the world is truly over." The actors had to sell the despair of a sterile, dying lab. That whispered secret Jenner told Rick—that everyone is already infected—set the stakes for the next eleven seasons.
The lasting legacy of the original six episodes
Why does this specific group still matter?
Because they didn't know it was going to be a hit. There was no "Walking Dead Universe" in 2010. There were no spinoffs in Paris or New York. There was just a group of actors in the Georgia heat, covered in corn syrup and red dye, trying to make a horror show that felt like a drama.

Most of these actors have moved on to massive things.
- Andrew Lincoln did stage work and returned for The Ones Who Live.
- Jon Bernthal became an action icon.
- Steven Yeun became a prestige cinema darling.
- Danai Gurira (who joined in season 3, but let's count the "original era" energy) became a Marvel powerhouse.
But they all point back to that first season as the "lightning in a bottle" moment.
Practical takeaways for fans and collectors
If you’re looking to dive back into the world of the actors of walking dead season 1, don't just rewatch the show.
- Check out the "Pilot" script: You can find it online. It shows how much the actors brought to the characters that wasn't on the page.
- Follow the "Darabont Connection": If you liked the vibe of season 1, watch The Mist (2007). You’ll see Carol, Dale, and Andrea all working together before the zombies arrived.
- Look for the "Making Of" documentaries: The physical prep these actors went through—"zombie school" for the extras and weapons training for the leads—was intense.
The magic of the first season wasn't just the gore. It was the fact that the cast treated the material like Shakespeare. They didn't wink at the camera. They didn't act like they were in a "genre" show. They acted like they were in a tragedy.
That’s why, sixteen years later, we’re still talking about them.
To truly appreciate the craft, go back and watch the pilot episode again. Ignore the zombies. Just watch Andrew Lincoln’s face when he realizes the sink doesn't work. Watch Lennie James (Morgan) struggle with the internal conflict of having to put down his undead wife. That is high-level acting that just happens to have monsters in the background.
The next step is simple. Stop scrolling through the endless spinoffs for a second. Go back to the beginning. Re-watch the first six episodes with an eye for the performances, not the kills. You'll realize that the reason the show became a global phenomenon wasn't the "walkers"—it was the people running from them.
