Logan Marshall-green on ‘Marshals’: The SEAL Brotherhood, the ‘Pain Train’ and Rigorous On-Set Preparation
logan marshall-green plays Pete Calvin, a mission-critical figure in the first season of CBS’ Marshals, and he says the role demanded both physical precision and emotional complexity. The actor described a compressed production timeline and intense tactical choreography that shaped how the five-person marshal team moves and fights together.
Ryan Sangster and the 'Pain Train' choreograph the marshal unit
Marshall-Green outlined how the show's combat sequences were built around a collective rhythm the cast nicknamed the "pain train. " Because Pete Calvin and Kayce are presented as Navy SEALs, the production brought in a military consultant, Ryan Sangster, an ex-SEAL, to sharpen the unit’s tactics. That decision flowed directly from the creative need to make the marshal team operate like the "tip of the spear": the effect was a regimen of tactical drills designed so the five members would move as one when breaching doors and clearing corners.
The accelerated schedule intensified that work. Marshall-Green said he received his offer and was "boots-on-the-ground" training and shooting within two weeks, and that most of the cast began training almost immediately. The compressed timeline forced a focus on team choreography—everyone learning where to go and how to "dance" together—rather than on slow, stepwise preparation.

Beyond close-quarters fighting, the role required equestrian skill and adaptation to a rugged production routine. Marshall-Green noted he had spent about half a year working as a ranchhand while making another film, and he used that experience to meet the horsemanship demands. Filming moved out to a location called Thousand Peaks, a site previously used for the first three seasons of Yellowstone, and the cast often traveled almost an hour to reach it.
The combination of weather and schedule shaped daily reality: some days consisted of what Marshall-Green called "six-day eps, " with early call times and cold conditions at the location. Practical necessities followed—he bought a four-wheel-drive truck once the Utah snow set in—yet he also emphasized small rewards, like being on horseback with a notable view even on difficult mornings.
Kayce, Pete Calvin and on-screen tension
Marshall-Green described Pete Calvin as a key influence on Luke Grimes’ Kayce, a Dutton family figure who joins the marshal team. Pete is the friend who helps Kayce secure the job and remains a formative presence despite wrestling with his own demons. That backstory shaped rehearsal and fight prep: the two characters’ shared SEAL background informed both their combat choreography and the subtler moments of their relationship.
