From Country Star to Hollywood Surprise
Riley Green’s transition from Nashville stages to television sets happened faster than anyone expected.

When Grimes learned Green had acting interest, the “Yellowstone” star offered him a role in “Marshals” without delay.
“I mentioned I had some interest in acting,” Green explains, “and I didn’t know it would turn into a job so quickly.” The 6-foot-4 singer with piercing blue eyes and natural comic timing brought an authenticity to Garrett that wouldn’t have been possible with traditional casting. His arrival signals a new chapter for the Alabama native’s creative career.

Garrett’s Troubled Past and Emotional Journey
Garrett arrives in Montana by bus, carrying little more than a guitar case and the weight of his military service. Green’s character fought in Afghanistan alongside Kayce, but his mysterious reappearance immediately raises suspicion from U.S. Marshals boss Pete Calvin. The first scene Green filmed threw him directly into the deep end: waking with night terrors and PTSD flashbacks, establishing Garrett as a man fighting invisible demons.
“They threw it on me so fast I didn’t have to get nervous about it,” Green reflects. The character carries significant emotional range, showing both the roughness of someone shaped by hardship and the vulnerability of a man seeking redemption. Green describes Garrett as “really kind of damaged,” a veteran grappling with trauma while reconnecting with his past.
The Alabama Line and Character Storytelling
| Element | Details |
| Character Detail | Garrett is written as a native of Alabama |
| Famous Line | “The only good thing to come out of there is the I-20, myself included” |
| Intent | Shows Garrett’s rough upbringing shaped who he became |
| Behind the Scenes | Green filmed for 2 months, keeping his signature mustache for continuity |
When Garrett delivers a criticism of Alabama during drinks with Kayce, it sparked immediate reactions from viewers. But Green clarifies for his Alabama fans that it’s pure acting. The line serves a narrative purpose: it instantly signals that Garrett is rough, shaped by growing up in difficult circumstances, using the character’s origins as shorthand for his troubled psychology.
The Campfire Performance and “My Way”
Green brought his own original song “My Way” to the April 26 episode, creating the show’s most emotionally charged moment. During a quiet campfire scene, Garrett performs for Kayce, and the intimacy reveals devastating layers. The song explores missing a lost love, directly reflecting Kayce’s grief over his late wife Monica, who died off-screen before the transition to “Marshals.”
“When I was told I was performing, and I didn’t know I was at first, I thought 100% this song was so perfect for that moment,” Green says. “There are some songs that are very cowboy-type songs.”

The scene left Luke Grimes in tears, with Kayce fighting back emotions while watching his old friend perform. Green’s natural musicianship translated seamlessly to television, proving that his core talent as a songwriter gave him unique insight into Garrett’s emotional vulnerability beneath the hardened exterior.
What’s Next for Riley Green’s Acting Career?
Green won’t reveal what happens to Garrett in the remaining episodes, tantalizing fans with the possibility of Garrett’s return in future seasons. Already, interest in his acting potential extends beyond “Marshals,” with the Screen Actors Guild reaching out and conversations beginning about additional roles. The singer’s distinctive look, featuring his trademark mustache, scruffy beard, and Western aesthetic, requires zero adjustment for film work.
When producers didn’t ask him to alter his appearance, Green realized how naturally aligned his look was with Garrett’s character. He spent two months filming while maintaining his signature style, though he admits the hardest part was resisting the urge to shave randomly when hot weather tempted him. As his acting journey unfolds, one thing remains certain: Riley Green has proven himself a credible actor with serious emotional range.
