Just over a year ago, amid the buzz of the Super Bowl festivities in Las Vegas, Justin Hartley introduced audiences to his new series, Tracker. The show’s main character, Colter Shaw, is a modern-day nomad traveling across America to help find missing people. From the outset, Hartley had a clear vision: he wanted to create something reminiscent of thrilling ’70s series like The Rockford Files — shows that offered straightforward, uncontroversial entertainment. His goal was to give viewers a break from heavily political or issue-driven dramas, focusing instead on strong storytelling and character-driven adventures. It was a bold move at a time when television was largely dominated by darker, more complex serials.
Hartley’s gamble quickly paid off. Tracker not only captured audience interest but exploded in popularity, becoming the most-watched new show of its first season. It was the first time since Survivor’s 2000 debut that a new series claimed such a title. Hartley, along with former This Is Us executive producer Ken Olin, managed to tap into a demand they believed was there but couldn’t be sure of until it materialized. Now, with season two nearing its end, Tracker continues to hold onto its substantial viewership, proving that audiences were indeed yearning for this kind of straightforward yet thrilling narrative format.
One of Hartley’s key creative goals for Tracker was to avoid making it a typical procedural where the main character remains unchanged. He explained that Colter Shaw is a character shaped and affected by the people he encounters and the cases he tackles. Although Shaw’s fundamental values stay consistent, the events of each episode leave marks on him, causing visible evolution over time. Hartley wanted the audience to see a genuine journey — someone who learns and adapts, rather than someone whose reactions become predictable. This decision added a layer of emotional authenticity and complexity to what could have easily been a formulaic show.

Tracker’s Success Surprises Hartley as New Talent and Bolder Storylines Strengthen the Series
Reflecting back, Hartley admitted he was hopeful but never certain that Tracker would resonate so strongly with viewers. Having experienced a similar sense of hope during his time on This Is Us, he knew that creators could feel a project was special, but success was never guaranteed. Every actor and producer starts a project believing in its potential, but ultimately, it’s the audience who decides. Hartley’s faith in the format and character-driven storytelling ultimately paid off, but he acknowledged that the TV industry always carries a degree of unpredictability, no matter how passionate the creators are.
As Tracker gained momentum, it naturally became a magnet for talent. Early on, Hartley leveraged his personal and professional relationships to bring familiar faces onto the show, including his wife, Sofia Pernas, and longtime friend Jensen Ackles. Now, with its popularity secured, Tracker has become a “cool show” that actors, directors, and writers want to be part of. This surge of interest has expanded the talent pool, giving the show access to higher-caliber guest stars and behind-the-scenes creatives, which in turn has only strengthened the overall quality of the series.
Season two saw Tracker exploring new thematic territories. Episodes like “Exodus” and “Mercy Seat” introduced spiritual, supernatural, and even horror elements. Hartley explained that these choices weren’t about changing the show’s identity but about raising the stakes and ensuring the danger Shaw faces feels real. Colter Shaw is portrayed as a highly skilled individual, but he is not invincible. He can suffer, fail, or even die. Maintaining that tension was crucial for keeping viewers invested and ensuring that each story remained unpredictable, suspenseful, and emotionally engaging.

Hartley Transforms Physically and Tracker Gears Up for High-Stakes Storytelling Ahead
When developing Shaw’s character, Hartley initially envisioned him as lean and agile, much like professional rock climbers who rely on strength-to-weight ratios. However, as the series evolved and Shaw found himself in more physically intense situations, Hartley decided to bulk up to match the increasingly demanding action scenes. He wanted Shaw to appear tough and resilient — someone capable of handling the brutal confrontations that became a regular part of the show. This decision required Hartley to adjust his fitness regimen, adding another layer of authenticity to his portrayal.
Episode 16, set amid snowstorms and rugged wilderness, proved particularly grueling to film. Shot in Whistler, Ontario, Hartley faced freezing temperatures, deep snow, and dangerous footing. Many of his slips and falls were genuine and ended up making it into the final cut. Adding to the challenge were massive industrial fans used to simulate blizzard conditions, making on-location dialogue impossible.
As a result, nearly every outdoor line had to be dubbed later in post-production. Despite the physical toll and production hurdles, Hartley described the experience as “worth it” to deliver a truly immersive and gripping episode.
The last five episodes of season two promise to be intense and revealing. Described as “little movies,” each episode stands on its own while collectively advancing the show’s central mystery: what happened to Colter Shaw’s father. As Shaw receives a crucial box from his sister Dory, long-buried secrets come to light, forcing him to confront painful truths. The final episodes will edge closer to resolving the mystery surrounding his father’s death — a storyline that has simmered in the background and now demands answers, offering an emotional and suspenseful payoff for long-time viewers.
As for what lies ahead, Hartley hinted at even bolder storytelling in season three. One idea under serious discussion is placing Colter Shaw on the run, using his skills not to find others but to evade capture himself after being framed. This new angle would tie into his complex family history and possible government conspiracies, deepening the show’s mythology without straying from its roots. Hartley and his team are committed to maintaining the spirit of Tracker while pushing its boundaries in ways that keep the audience hooked and excited for more.
