Ackles was cast as Russell in Tracker in April 2024. The role came months after the series premiered, and he first appeared in Season 1’s penultimate episode “Off the Books,” which aired on May 12, 2024. In that episode, Russell asks Colter for help finding a missing former Army buddy who has been acting paranoid for weeks, while their complicated family history and tensions over their father’s death loom over their reunion.
“Well, right now he is about probably 100 meters away from me. He’s in at least one [episode], and we’ll have him back when we can. I think probably in the new year, we’ll have him back for a few.”
When Russell returns, rather than provide answers about the file he read last season, he will come for his brother’s help. According to Hartley, one of his friends is in grave trouble, “not a self-inflicted thing,” but because of an unexpected situation. So Russell thinks of his brother Colter, whom he believes can help. “So, he reaches out, and, of course, Colter’s willing to help, and it reunites the two brothers, and they go on this pretty epic journey,” Hartley added.

Collider Exclusive · Action Franchise Quiz What Action Series Would You Thrive In? Wick · Fast · Mission · Die Hard
Four franchises. Four completely different ideas of what a hero is: the assassin with a code, the family that never leaves anyone behind, the man who does his own stunts, and the guy who simply refuses to die. Only one of them runs on your particular brand of trouble. Eight questions will tell you which one you would survive.

01
How does a room know you’ve walked into it? Every action hero arrives differently. Some of them arrive before they arrive.

02
It turns physical. What does your fighting actually look like? Choreography is character. Yours says something about you.
Advertisement
03
Who is standing beside you when it starts? Some franchises are built on a team. Others are built on one person walking in alone.

04
It has gone badly wrong. What keeps you upright? Act two exists to find out what you’re actually made of.

05
There’s a vehicle. What are you driving, and how? No action franchise has ever survived without a car chase. This one is yours.

06
How do you feel about the people giving the orders? There is always an institution. There is rarely a good one.

07
Underneath all of it, what are you actually doing this for? The stunts are the reason people come. This is the reason they stay.

08
When the credits roll, what do people say about you? Every franchise is really an argument about what makes someone worth watching.

Casting Has Been Completed Your Franchise Is…
Four action series. One of them is built around exactly the way you
handle pressure, people, and a room that has just gone very quiet. Here is where you would survive
the trilogy, and probably headline it.

John Wick · Chapters 1–4 · 2014–2023
John Wick
You are precision with a grudge. You don’t posture, you don’t
escalate, and you don’t warn anybody twice. That is exactly why the people who know you are
so careful never to be the reason you start.
Advertisement
The Wick films run on discipline: an underworld with actual etiquette, a hero who
honours every rule of it, and a world that unravels the instant someone breaks one
against him.
You share that quality. You are extraordinarily reasonable right up to the line, and
then completely immovable past it.
Focus, commitment and sheer will. You’d be the one carrying grief through three sequels
and turning it into technique rather than noise.
People wouldn’t call you dangerous. They’d say your name quietly and let that do the
work.
The Fast and the Furious · Fast X · 2001–2023
Fast & Furious
You understand the thing the whole franchise is secretly about:
the cars are spectacular, but the crew is the point. You collect people, you keep them, and
you’d drive through a building for any one of them.
Advertisement
This series went from street racing to orbit without ever changing its actual subject,
because loyalty scales and plot doesn’t have to.
You have the same instinct. You build a family out of whoever turns up, and then you
defend it past the point of reason.
You’d thrive here because the franchise rewards exactly your strengths: warmth, nerve,
an absolute refusal to leave anyone behind, and a relaxed relationship with physics.
The mission can wait. The barbecue cannot.
Mission: Impossible · The Final Reckoning · 1996–2025
Mission: Impossible
You over-prepare and then take the dangerous part yourself
anyway. It looks like control, but it’s really responsibility. You have never worked out how
to ask somebody else to carry the risk.
Advertisement
This is the franchise of the plan that collapses on schedule: the team, the mask, the
rooftop, and the one person sprinting flat out because sprinting is all that’s left.
You share that refusal to accept an outcome. Told the odds, you treat them as an
administrative error.
You’d thrive here because these films reward competence and loyalty in equal measure.
The mission matters, but nobody on the team gets left on the wrong side of a door.
Some people delegate the cliff. You have never once been that person.
Die Hard · A Good Day to Die Hard · 1988–2013
Die Hard
You are not the most trained person in the building, the best
equipped, or the one anybody would have picked. You are simply the one still standing at the
end, which turns out to be the only qualification that matters.
Advertisement
Die Hard invented the modern action hero by making him mortal: outgunned, out-planned,
bleeding, and extremely funny about it.
You share that stubbornness. Adversity doesn’t make you noble, it makes you sarcastic,
and then it makes you unstoppable.
You’d thrive here because these films reward improvisation and nerve over preparation,
and you’ve never had the luxury of preparing anyway.
You didn’t want any of this. You just declined to be the person who let it happen.
Colter and Russell Are in a Good Place in ‘Tracker’ Season 4
When the brothers first reunited in Tracker, they were estranged, with Colter suspecting that Russell might be involved in their father’s death. However, they’ve since made amends on screen. Still, Russell may be hiding something from Colter, but that most likely won’t affect their relationship in this upcoming season, according to Hartley, who confirmed they will be in a good place.

“I don’t think necessarily he’s suspecting anything new. I also think that he always assumes that his brother is keeping something from him. So, I don’t know if it completely changes. I don’t think there’s anything new necessarily about his brother, new suspicions, but I think that this lingering suspicion that his brother’s always keeping something from him is still there.”
Inspired by Jeffery Deaver‘s bestselling novel The Never Game, Tracker follows lone-wolf survivalist Colter, who, driven by the troubles of his past, uses his instincts to earn a living by finding the missing. The action drama premiered on February 11, 2024, to critical acclaim, with the first season currently holding an 89% approval rating on Rotten Tomatoes. It was renewed for Season 4 on January 22, 2026.
Tracker Season 4 premieres on October 4, 2026, on CBS, with the premiere episode also streaming on Paramount+. Stay tuned to Collider for more information.
