Justin Hartley Confirms Tracker Season 4 Production Underway with Los Angeles Relocation

Tracker season 4 has officially entered production, with Justin Hartley confirming the news through a social media update on July 7. The CBS drama will relocate to Los Angeles for its upcoming season, set to premiere this fall, while Ken Olin—a veteran producer and actor from Thirtysomething—will direct the season's first episode.

Production Details and Creative Direction

Hartley shared the production milestone on his Instagram story, signaling that the writers and crew have moved from the development phase into active filming. Olin brings considerable history to the project, having served as an executive producer on Hartley's previous series, This Is Us, establishing a established working relationship between the director and star.

The shift in production base represents a significant operational change for the series. Rather than remaining stationary, however, Hartley emphasized that the relocation complements rather than compromises the show's core identity. He explained to The Wrap in May that Tracker functions as a road-centric drama where the protagonist, Colter Shaw, travels across America meeting strangers and resolving their conflicts.

Expanded Creative Possibilities

The Los Angeles base unlocks access to diverse filming regions that were previously difficult to reach. Hartley noted that the new arrangement allows production to shoot in multiple geographic settings—New York, Washington D.C., desert regions, Texas, and coastal areas—creating visual variety that serves as a character element itself. This flexibility maintains the show's fundamental structure while offering viewers different backdrops for Shaw's investigations.

Season 4 arrives following the resolution of the series' central mystery in season 3. The finale provided closure regarding Colter's father's murder, a narrative thread that has anchored the show since its pilot episode. With that arc concluded and Russell Shaw's temporary exit, the series enters a new creative chapter focused on self-contained cases rather than serialized mythology.
