Boyka: Undisputed IV

I spent forty minutes trying to find a working charger for my old iPad before realizing I could just watch this on my phone while sitting on my kitchen floor—not exactly the IMAX experience, but for Yuri Boyka, a cold linoleum floor feels strangely appropriate. There is a specific kind of dignity in the "Direct-to-Video" (DTV) market that most mainstream audiences never see. While the multiplexes are busy drowning us in gray CGI soup and stunt doubles who look like they’re being hoisted by invisible pulleys, Scott Adkins is out here actually hitting people. Or at least, making the "art of the hit" look like a holy sacrament.

The Heavy Weight of a Holy Warrior

Boyka: Undisputed IV isn’t just a movie about a guy who can kick people in the face while rotating 720 degrees in mid-air—though it definitely has that. It’s a surprisingly somber meditation on atonement. We find Yuri Boyka, a character who has evolved from a narcissistic villain in Undisputed II to a broken anti-hero in III, now living in Ukraine. He’s found God, he’s winning underground fights to fund his local church, and he’s finally on the verge of going "legit."

Then, he kills a man in the ring.

This isn't a "shrug it off" moment. The film leans into the darkness of that event. When Boyka realizes the man he killed, Viktor, has a widow named Alma (Teodora Duhovnikova) who is being essentially held as collateral by a local mobster named Zourab (Alon Aboutboul), the movie shifts gears. It stops being a sports film and becomes a gritty, modern western. Boyka travels back to Russia—the one place he’s a wanted man—to offer his life and his fists to buy her freedom.

What I love about this era of Scott Adkins collaborations with director Todor Chapkanov (and the franchise architect Isaac Florentine, who produced here) is the sheer earnestness. There’s no winking at the camera. Boyka is a man of few words and terrifying intensity. He treats every fight not as a sport, but as a trial by fire. He looks like he’s perpetually one bad day away from punching a hole through a brick wall, and yet, his interactions with Alma are played with a delicate, tragic restraint.

The Geometry of the Bone-Crunch

Let’s talk about the action, because that’s why you’re killing five minutes before your bus arrives. The choreography by Tim Man is some of the best of the 2010s, period. In an age where The Avengers uses ten cuts to show a single punch, Undisputed IV lets the camera breathe. You see the setup, the execution, and the impact.

There is a sequence where Boyka has to fight two brothers simultaneously. It’s a masterclass in spatial awareness. You see him tracking both bodies, using one as a shield, and delivering those signature "Guyver" kicks that defy the laws of physics. It’s not just "fast"—it’s clear. You feel the weight of every landed blow. When Boyka faces off against the final boss, a literal giant named Koshmar (Martyn Ford), the film turns into a "David vs. Goliath" struggle that feels genuinely hopeless. Ford is a terrifying physical presence—a mountain of muscle and tattoos who looks like he eats smaller martial artists for breakfast.

The production values, despite being a Bulgarian-shot DTV production, are remarkably high. They use the crumbling, industrial aesthetic of Eastern Europe to hammer home the "Dark" modifier. This isn't the shiny, neon-lit underground of John Wick; this is a place that smells like damp concrete and stale sweat. The score by Stephen Edwards punctuates the hits with a heavy, rhythmic thrum that keeps your heart rate elevated.

The DTV King in a Streaming World

The tragedy of Boyka: Undisputed IV is that it exists in a cultural blind spot. Released in 2016, it arrived just as the mid-budget action movie was being swallowed whole by streaming giants. Because it didn't have a massive theatrical rollout, it’s often dismissed as "one of those fighting movies." But it’s actually the peak of its form.

Scott Adkins has famously spoken about how rampant piracy almost prevented this movie from being made. It’s a reminder that in our current era of "content" saturation, these smaller, labor-of-love action films are the ones that actually take the most risks. There’s no stunt double for most of what you see here. That’s Adkins’ actual body hitting the mat.

Apparently, during the filming of the final fight, the production was so tight on time that they were shooting massive amounts of choreography in single days. You can see the exhaustion on the actors' faces, and it works perfectly for the story. This is a film about a man who is physically and spiritually spent, fighting one last time for something that isn't his own ego. It’s intense, it’s unglamorous, and it’s arguably the best pure martial arts film of its decade.

If you can get past the "sequel to a sequel" stigma, you’ll find a movie with more heart and better craftsmanship than 90% of the blockbusters currently clogging up your Netflix queue. It’s a dark, bone-crunching redemption story that proves you don’t need a $200 million budget to create a hero worth rooting for. Watch it on the biggest screen you can find, and maybe have an aspirin ready for the sympathetic pains you’ll feel in your ribs.
