You probably recognize that face. It’s the kind of face that has anchored a dozen different dramas over the last twenty years. If you’ve been watching the hit CBS series Tracker, you know he's playing the rugged, calculating, and slightly emotionally distant "rewardist" who lives in an Airstream.
So, who plays Colter Shaw? That would be Justin Hartley.
Most people know him as Kevin Pearson from This Is Us, the charismatic actor struggling for depth. But in Tracker, he has basically flipped the script. He isn't the guy crying on a kitchen floor in Pittsburgh anymore. He’s out in the wilderness, calculating percentages of survival and finding people who don't want to be found.
From Pine Valley to the Great Outdoors
Hartley didn't just stumble into this role. Honestly, he’s been a staple of television for so long that he’s become a bit of a chameleon. Before he was Colter Shaw, he was a billionaire superhero.
Fans of Smallville remember him as Oliver Queen (Green Arrow). He brought a certain swagger to that role that felt very different from the darker versions of the character we saw later. Then there was the soap opera circuit—Passions and The Young and the Restless—where he really honed that "leading man" energy.
Why Justin Hartley is the Only Choice for Colter Shaw
The character of Colter Shaw actually comes from the mind of thriller novelist Jeffery Deaver. If you haven't read The Never Game, it’s the book that started it all. In the novels, Shaw is this highly analytical, almost robotic survivalist. He’s obsessed with probabilities.
When CBS decided to adapt it, they needed someone who could play "stoic" without being "boring." That’s a tough needle to thread.
Hartley brings a warmth to the role that isn't always on the page. He makes Colter feel like a real person, even when he's doing things like jumping off cliffs or tracking a kidnapper through a dense forest. He’s also an executive producer on the show, which means he has a massive say in how the story unfolds.
The Survivalist Vibe
Colter Shaw isn't a cop. He’s not a private investigator. He calls himself a "reward seeker." Basically, he finds people, grabs the cash, and moves on to the next town in his truck.
To get into character, Hartley reportedly focused on the physical side of things. He’s not just "TV fit" for this role; he actually looks like he could survive a week in the woods with nothing but a pocketknife. He’s talked in interviews about the "unconventional" upbringing Colter had—being raised by a paranoid survivalist father (played by Lee Tergesen) who taught his kids how to track humans like prey.
That backstory is what makes the show work. It’s not just a "case of the week" procedural. It’s a family drama wrapped in a survivalist thriller.

The Family Tree: Who Else is in the Cast?
While Hartley is the engine, he isn't alone. The casting for the Shaw family has been pretty top-tier.
- Jensen Ackles plays Russell Shaw, Colter’s estranged older brother. The chemistry between Hartley and Ackles is honestly one of the best parts of the second season. They feel like brothers who genuinely love each other but also might punch each other in the face at any moment.
- Melissa Roxburgh (from Manifest) shows up as Dory, the younger sister who just wants everyone to be normal for five minutes.
- Mary McDonnell (the legend from Battlestar Galactica) plays their mother, Mary Dove Shaw. She’s the keeper of the family secrets, and there are a lot of them.
Behind the scenes, the show is a bit of a This Is Us reunion. Ken Olin, who was a major force behind that show, is an executive producer and director here too. You can feel that influence in the way the show focuses on character beats rather than just the action.
It’s Basically a Modern Western
If you look at Tracker closely, it’s not really a crime show. It’s a Western.
Colter is the lone cowboy. The Airstream is his horse. He rides into town, fixes a problem the local law can't handle, and rides out. Justin Hartley plays into this perfectly. He has that classic, quiet masculinity that reminds you of guys like Clint Eastwood or Tom Selleck, but with a modern, sensitive edge.
He’s also not afraid to look vulnerable. Colter is haunted by what happened to his father, and Hartley isn't afraid to let that "cracked" version of the character show through the tough exterior.
What’s Next for Colter Shaw?
As of 2026, Tracker is still one of the biggest shows on network TV. People are clearly hungry for this kind of storytelling. It’s simple, it’s effective, and it’s led by an actor who finally found a role that fits him like a glove.
If you’re just starting the show, pay attention to the way Colter talks about percentages. It’s his way of managing his own trauma. It’s a small detail, but it’s what makes the character more than just another guy with a gun.
