When you see a retired UFC Heavyweight Champion dancing to disco music while screaming about "victory dances," you usually assume it’s a fever dream or a very specific corner of YouTube. But for anyone who watched the 2012 flick Here Comes the Boom, that was just Bas Rutten being Bas Rutten.
Bas Rutten Here Comes the Boom wasn’t just another athlete cameo. It was the moment "El Guapo" officially traded his legendary liver shots for a permanent spot in Hollywood’s heart.
Honestly, most sports movies use pro athletes as props. They stand in the background, look intimidating, and maybe grunt once. But Bas? He basically stole the whole show from Kevin James. If you’ve ever wondered how a guy who used to break ribs for a living ended up playing a charmingly eccentric citizenship student named Niko, the backstory is actually better than the script itself.
The Bromance You Didn't Know About
Kevin James didn’t just pick a random fighter from a hat. He and Bas Rutten have been tight for years.
Long before they were filming scenes at the MGM Grand, Kevin James was a legitimate MMA fanatic. You can actually spot James wearing a "Bas Rutten MMA System" shirt in old episodes of The King of Queens. They weren't just business associates; James actually trained with Bas.

When James started writing the script for a movie about a biology teacher moonlighting as a cage fighter to save a high school music program, Bas reached out. He didn’t want a handout. He just wanted a tiny role—maybe a guy in the background or a quick walk-on.
James had a better idea.
Instead of a five-second cameo, he wrote Bas into a major supporting role. He became Niko, the former fighter turned yoga instructor/citizenship student who helps Scott Voss (James) navigate the brutal world of the UFC.
Why the Character of Niko Worked
Niko isn't just a generic trainer. He’s the heart of the movie's comedy.
Think about the "Disco Street Fighting" scene. Bas Rutten is leading a class of seniors through a workout that involves rhythmic striking and a celebration dance. It’s hilarious because it’s not entirely a joke. If you know anything about Bas’s real-life "Self Defense" videos—the ones where he talks about "Danga-da-danga-da-dang!" while hitting someone with a barstool—you know that Niko is just a slightly more PG version of the real Bas Rutten.
Factual Highlights of Bas in the Film:
- The Name: He plays Niko, a former MMA fighter with a "bad neck" (a nod to Bas's real-life injuries that forced his retirement).
- The Citizenship Plot: A huge chunk of the movie involves Niko trying to pass his US citizenship test, which mirrors Bas Rutten’s real-life journey of becoming a US citizen.
- The Training: Bas actually helped train Kevin James for the role. James wasn't just using a stunt double for everything; he dropped significant weight and learned real striking patterns from one of the best to ever do it.
Realism in a Comedy?
Most MMA movies are terrible. They get the moves wrong, the timing is off, and the "cage" looks like it was built in someone's garage.
Here Comes the Boom was different because the UFC actually got involved. This was the first major feature film the UFC allowed to use its full branding. Because of that, Bas wasn't the only real fighter on set. You had Mark Muñoz, Krzysztof Soszynski, and even Jason "Mayhem" Miller playing the "villains" or opponents.
Bas acted as a bridge. He made sure the techniques looked somewhat legitimate, even when the situations were ridiculous. When Niko tells Scott Voss that he has to "embrace the pain," it’s coming from a guy who fought with ruptured discs and broken hands.
The Transition from the Octagon to the Screen
Bas Rutten is a rare breed. Most fighters struggle with the "acting" part because they are trained to hide their emotions. You can’t show weakness in a fight.
But Bas is naturally theatrical. In his Pancrase days in Japan, he was known for his "Bas Rutten Jump" after a win. He understood showmanship long before he met Kevin James.

In Here Comes the Boom, he showed a range that surprised critics. He was vulnerable during the citizenship scenes and terrifying (but funny) during the training sessions. He proved that he wasn't just "the fighter guy"—he was a comedic actor with actual timing.
What Most People Miss About the Movie
A lot of viewers think the movie is just a silly comedy. On the surface, yeah, it is. But for the MMA community, it was a love letter.
When you see Bas and Henry Winkler (the music teacher) standing in the corner of a cage, it represents the weird, "misfit toy" energy of early MMA. Bas represents the old guard—the pioneers who fought for peanuts in smoke-filled gyms—helping a newcomer find his way.
Actionable Takeaways for Fans
If you're revisiting the movie or just discovering the legend of El Guapo, here is how to appreciate the Bas Rutten era:
- Watch the "Self Defense" Videos: Go to YouTube and search for Bas Rutten’s street defense. You will see exactly where the inspiration for his character's "boom" came from.
- Look for the Cameos: See if you can spot Joe Rogan, Mike Goldberg, and Herb Dean. They all play themselves, adding a layer of authenticity that Bas helped facilitate.
- Appreciate the Work Ethic: Look at Kevin James's physique in the final fight. He actually learned to move like a fighter under Bas's guidance.
The reality is that Bas Rutten Here Comes the Boom remains one of the best representations of a professional athlete successfully crossing over into Hollywood without losing their soul. He didn't have to pretend to be someone else; he just turned his own natural charisma up to eleven.
To truly understand the "Niko" character, you should check out Bas Rutten's 2015 UFC Hall of Fame induction speech. It’s got the same mix of humor, heart, and occasional intensity that made him a star on the big screen.
Next Steps:
Go back and watch the "Citizenship Song" scene again. Now that you know Bas was actually going through that process in real life, his performance carries a lot more weight. You can also look up his "Inside MMA" hosting clips to see how he transitioned this movie fame into a long-term broadcasting career.
