When Tracker hit the screen, fans immediately fell in love with Justin Hartley’s portrayal of Colter Shaw — the enigmatic survivalist and “reward seeker” who solves missing person cases across America. But beneath the rugged charm and suspenseful storytelling, there’s a lot more to Hartley’s performance than meets the eye.
In this article, we’re diving deep into 10 things you didn’t know about Justin Hartley’s role in Tracker — from secret prep work to behind-the-scenes moments that reveal how he brought Colter Shaw to life.
1. Justin Hartley Helped Shape the Character of Colter Shaw
Many fans don’t realize that Justin Hartley isn’t just the star of Tracker — he’s also one of its executive producers. Hartley was heavily involved in shaping Colter’s personality, dialogue, and emotional depth.
He once mentioned in an interview that he wanted Colter to feel “like a man who’s been through the fire but still believes in doing good.” That’s why the show’s tone feels so grounded and emotionally rich — Hartley poured his own creative energy into every detail.
2. The Role Was Custom-Tailored for Him
Believe it or not, the producers had Justin Hartley in mind from the very start. After his success on This Is Us, they wanted an actor who could balance emotional vulnerability with physical toughness — and Hartley fit the bill perfectly.
The writers even adjusted several parts of the script to match his acting strengths and charisma. That’s how deeply connected he is to the DNA of the show.
3. Hartley Did Most of His Own Stunts
Yes, you read that right! Justin Hartley isn’t afraid to get his hands dirty. For Tracker, he trained extensively to perform most of his own stunts — from chase scenes to survival sequences.
He worked with professional stunt coordinators and even took wilderness survival lessons to make every move look authentic. The result? Realism that draws you right into Colter Shaw’s world.
4. Colter’s Philosophy Mirrors Hartley’s Own Mindset
Justin has often said that Colter’s moral compass — his belief in helping people for the right reasons — resonates with his own values.
In interviews, he’s described himself as someone who “believes in doing the right thing even when no one’s watching.” That’s exactly who Colter is: a man guided by integrity rather than fame or fortune.
It’s this alignment that makes his portrayal so believable.
5. The Series Was Inspired by a Real Novel
Tracker is based on The Never Game, a bestselling novel by Jeffrey Deaver. But Hartley didn’t just copy the book version of Colter Shaw. Instead, he collaborated with the creative team to build a TV adaptation that expanded Shaw’s emotional backstory and family trauma.
Hartley’s version of Colter is grittier, more human, and far more layered than the original — and fans can’t get enough of it.
6. He Relates to Colter’s Lone-Wolf Nature
Justin Hartley has admitted he shares some similarities with Colter — especially his independent streak. While Hartley is happily married in real life, he’s also described himself as someone who enjoys solitude and reflection.
Playing a character who spends much of his time traveling alone, solving mysteries, and trusting his instincts came naturally to him.
7. Filming Took Place in Extreme Conditions
The crew didn’t rely on fancy green screens for Tracker. They shot in real outdoor locations — deserts, forests, and mountain trails across North America.
Justin faced freezing temperatures, sweltering heat, and unpredictable weather, but he insisted on authenticity. According to one behind-the-scenes source, he refused body doubles in many dangerous sequences just to keep things real.
8. Hartley Added Emotional Depth to the Action
Sure, Tracker delivers heart-pounding suspense, but Hartley pushed for emotional storytelling too. He believed that audiences wouldn’t just root for Colter because he’s a hero — they’d root for him because he’s human.
Every case Colter takes on connects back to his own emotional scars. That vulnerability is pure Hartley magic — the same quality that made This Is Us a global phenomenon.
9. The Show Was Designed to Evolve with Hartley’s Career
Here’s something most viewers don’t know: Tracker was strategically developed to align with Hartley’s long-term career goals. After years of being part of ensemble casts, he wanted a lead role that challenged him physically and emotionally.
Tracker gave him both — a chance to showcase action-star intensity while keeping the heart that fans love him for.
10. There’s a Hidden Connection to “This Is Us”
Eagle-eyed fans have spotted subtle Easter eggs throughout Tracker that nod to This Is Us. For instance, Colter’s flashback scenes often use warm lighting and nostalgic framing — similar to how This Is Us depicted emotional memories.
Some crew members from This Is Us even joined Tracker, creating an emotional continuity that longtime fans instantly recognize.
