You probably know the name Alex Fine because of the headlines. Maybe you saw him standing next to his wife, Cassie, during some of the most difficult public moments of her life. Or maybe you’ve seen him on Instagram, looking like he was carved out of granite. But lately, there’s been a shift. The "celebrity trainer" tag is starting to feel a bit too small for what he’s actually doing.
He’s an actor now. And honestly, he’s actually getting real roles in shows people care about.
It wasn't just a random whim. Fine didn't just wake up and decide to be in front of the camera because he was bored of lifting weights. He’s been quietly building a resume in the Western and crime genres that suggests he’s looking for longevity, not just a cameo. If you’re looking for a list of Alex Fine movies and TV shows, it’s a short list for now, but the projects are surprisingly high-caliber.
The Yellowstone Connection and 1883
Most people first noticed him in 1883.
For those who haven't fallen down the Taylor Sheridan rabbit hole, 1883 is the prequel to Yellowstone. It’s gritty. It’s dirty. It’s definitely not the kind of show where you just show up looking pretty and call it a day. Fine played a character named Grady.
He appeared in two episodes: "Behind Us, A Cliff" and "River."
It wasn't a massive, series-defining role, but it was a foot in the door of one of the biggest franchises in modern television. Working on a Sheridan set is basically a trial by fire. You’re dealing with horses, 19th-century gear, and a creator who demands authenticity. For a guy who grew up playing D1 football at Central Michigan and actually competes in professional bull riding, the "cowboy" thing isn't an act. It’s kind of just his Tuesday.
Breaking Down American Primeval
The momentum didn't stop with the Dutton family.
By 2025, Fine landed a much more significant role in the Netflix miniseries American Primeval. This is a big deal. The show is directed by Peter Berg—the guy behind Friday Night Lights and Lone Survivor. Berg likes "tough guy" actors who can handle physical roles, and Fine fits that mold perfectly.
In this series, Fine plays a character named Gant.
American Primeval is basically a raw, un-glamorized look at the birth of the American West. It’s about survival, religion, and the clashing of cultures. Fine’s involvement across six episodes shows that he’s moved past the "blink and you'll miss him" phase of his career. He’s a recurring presence.
Moving Into Crime Drama with MobLand
If Westerns are his foundation, crime drama seems to be his next target.
Fine was cast in MobLand (also known as The Agency or Guy Ritchie’s untitled crime series depending on the production stage and region). This isn't some low-budget indie project. We’re talking about a show that features heavy hitters like Tom Hardy, Pierce Brosnan, and Helen Mirren.
He plays Donnie.
Donnie is reportedly an adversary to Tom Hardy’s character, Harry. Imagine that for a second. You go from training people in a gym to playing an antagonist against Tom Hardy in a Guy Ritchie production. It’s a massive leap. It also suggests that casting directors see a certain "edge" in him that works for high-stakes, gritty storytelling.
The Horror Stunt: The Resurrection of Charles Manson
Beyond the prestige TV stuff, he also dipped his toes into the horror-thriller genre.
In 2023, he appeared in The Resurrection of Charles Manson. He played a character named Travis. The movie stars Frank Grillo, who is another actor known for his extreme physical fitness and "tough guy" persona.
The film follows a couple who goes to a desert Airbnb to film an audition, only to find themselves caught up in a cult. It’s not exactly The Godfather, but it gave Fine a chance to work in a different genre and see how he handled the thriller/horror vibe.
Why Producers Are Actually Hiring Him
It’s easy to be cynical. You see a handsome guy who is famous on social media and think he’s just getting "influencer roles."
But Hollywood likes Alex Fine for a few specific reasons:
- He’s a "Natural" Athlete: Producers don't have to spend six months training him to look like he can handle a horse or a fight scene. He’s already there.
- The Bull Riding Factor: He’s a member of the Professional Bull Riders (PBR) circuit. In a world where actors use stunt doubles for everything, having a guy who actually rides 2,000-pound animals for fun is a huge asset for Westerns.
- Work Ethic: You don't build a fitness empire like Almost Home or train elite athletes like Saquon Barkley by being lazy. That discipline translates well to 14-hour days on a film set.
Honestly, the transition from "celebrity trainer" to "actor" is a well-worn path. Think about Arnold Schwarzenegger or even more recently, guys like John Cena. They start with the physical, but the ones who stick around are the ones who can actually deliver a line without sounding like a robot.
What’s Next for Alex Fine?
There are rumors about a project titled Breathe Deep where he might play a character named Valentine, though details on that have been pretty tight-lipped.
What’s clear is that Fine is building a specific brand. He isn't trying to be a rom-com lead. He’s carving out a space in masculine, high-stakes dramas—the kind of stuff Guy Ritchie and Taylor Sheridan specialize in.
If you want to follow his career, the best move is to watch 1883 on Paramount+ and keep an eye out for the release of American Primeval on Netflix. You’ll see the progression from a background cowboy to a legitimate supporting actor.
The "husband of Cassie" or "the guy who trains the Riverdale cast" labels are still true, but they're no longer the whole story. Alex Fine is becoming a fixture in the kind of television that people actually binge-watch.
To keep track of his upcoming roles, you should monitor the credits for Guy Ritchie's upcoming Showtime projects. His role as Donnie in the London-based crime series is likely his biggest test yet, especially sharing scenes with actors of Tom Hardy's caliber. Watch 1883 first to see his roots, then jump into American Primeval to see his growth as a recurring performer.
