How Scott Adkins Became Killa in John Wick 4: BTS Secrets That’ll Make You Obsessed 🔥

Even in 2026, John Wick: Chapter 4 still has action fans completely shook — and a huge part of that obsession is Killa, the larger-than-life German brawler who throws down with John Wick in a water-soaked Berlin club. The character? Iconic. The performance? Low-key legendary. And the man behind the fat suit? None other than martial arts powerhouse Scott Adkins. He totally disappeared into the role, and fans are still not over it. So let’s spill the tea on how Killa was born, the fights, the fashion, and the fiery passion that went into creating one of the Wick universe’s most unforgettable villains.

🎭 The Role That Almost Didn’t Happen

When director Chad Stahelski called Scott Adkins with an offer to join the John Wick universe, it was a major “heck yes” moment. But there was, as they say, a twist. Chad was like, “I want you in the film… but there’s a catch.” That catch? A full-body fat suit and a completely off-brand physicality for someone known for landing insane spinning kicks. At first, Chad wasn’t even sure if Scott would be up for it. But for Scott, it was the creative challenge of a lifetime. He saw it as a rare chance to build a character from the ground up, to truly vanish into a role — and since it was his one shot to be in a John Wick movie, he went all in. No cap.

💪 Building Killa: From Mike Tyson to Sammo Hung

Scott knew right away that if he started doing his signature jump-spin-back-kicks while wearing a padded suit, the illusion would shatter. The audience would just think, “Oh, that’s Scott in a fat suit.” So the mission was to sell the weight. The martial arts had to stay grounded — much like the rest of the John Wick franchise, which, despite being gloriously over-the-top, keeps its hand-to-hand combat surprisingly realistic. Scott and the stunt team crafted Killa as a big, fat German kickboxer with a Mike Tyson–style brawler vibe. Heavy, powerful, and deceptively quick when it counted.

But the influences didn’t stop there. Scott based Killa’s voice on Ronald Lacey’s menacing Gestapo agent from Raiders of the Lost Ark (“Yes Fräulein, what shall we talk about?”). For the look, they drew from the suave gambling figure in Casablanca, and for the martial arts energy, all eyes were on the legendary Sammo Hung. In a total vibe move, Chad dressed Killa in the exact same suit Sammo wore in SPL. Talk about a cinematic Easter egg!

🎬 Chad Stahelski: The Visionary Behind the Mayhem

Working with Chad Stahelski was, according to Scott, a whole different level of artistry. Chad’s background as a stuntman, stunt coordinator, and second unit director gives him an encyclopedic understanding of action — but he’s also got a painter’s eye. Much of John Wick 4 is inspired by the Baroque artist Caravaggio, and you can feel that dramatic, chiaroscuro elegance in every frame. Chad’s father was even a plumber who installed similar water features at home, which is how the idea for that stunning cascading water in Killa’s club fight was born. Pumping that much water through three floors of an industrial building? An absolute nightmare to execute, but so worth it.

While filming, Scott was blown away by how Chad and cinematographer Dan Laustsen would carve out time to make every shot look pristine and classy. “That’s what cinema is,” Scott says. The night shoots were grueling, but that’s exactly what gives John Wick its signature mood. And here’s a juicy BTS tidbit: the banging club music wasn’t added in post — it was blasting on set during the entire fight sequence. The vibe was immaculate, and it shows.

🕶️ The Fat Suit That Fooled Everyone

One of the biggest flexes of Scott’s performance is that so many viewers didn’t even recognise him. The suit made him look bigger, but it was Scott’s movement that sold the character. He moved more laboriously, with an out-of-shape swagger that made Killa feel like a washed-up gladiator. The idea was that once upon a time, this guy was a devastating martial artist who could still hold his own. When Killa gets shot in the behind and then suddenly unleashes some legit moves, the surprise is chef’s kiss. It works because the audience believes in that weight.

💧 Water, Axes, and Absolute Chaos

That club fight scene? Absolutely fire. Scott and his squad came strapped with axes, and the stylized action, mixed with water pouring down all around them, made it one of the most visually distinct brawls in the entire franchise. Even within the already hyper-stylized John Wick universe, that section stands out as next-level. Scott loved every second of it and is proud to have been part of such a cinematic moment.

🎙️ Keanu Reeves: The Ultimate Professional

We have to talk about Keanu, because Scott certainly does — and with total admiration. Keanu’s likability is off the charts. Even though John Wick is a stone-cold killer who takes down 50+ goons in increasingly brutal ways, audiences root for him simply because it’s Keanu. His work ethic is next level: he doesn’t stop, he doesn’t complain, he just gets on with it. Considering he’s not getting any younger and the stunts are literal insanity (hello, that staircase sequence!), it’s mind-blowing how dedicated he is. Scott’s takeaway? Unfiltered respect.

🎞️ Practical Effects Forever

When the conversation turns to CGI vs. practical stunts, Scott doesn’t hesitate. He’s all about the practical life. Use CGI sparingly, he says — only when there’s no other choice or to keep people safe. Too much digital trickery and the action starts feeling like a cartoon. John Wick’s commitment to real stunts, real hits, and real sweat is a huge reason why the franchise still hits different in 2026.

🚀 The Future of Killa (and the John Wick Universe)

With Ballerina and The Continental already out and the Wick universe continuing to expand, Scott is totally down to return. He’d love to explore a Killa prequel — how the man got fat, the “before and after” story. Even if that doesn’t happen, Scott joked he could come back as Killa’s thin brother seeking revenge, doing yet another German accent. Sign us up!

And when asked who else should join the John Wick universe, Scott immediately name-dropped Jason Momoa — and fans are already manifesting it. Can you imagine Momoa bringing that Fast X energy to the High Table world? It would be pure chaos and we are here for it. Scott also couldn’t help but mention he’d love to share screen time with Mark Dacascos (the sushi chef assassin from Chapter 3) or the legendary Laurence Fishburne — icons only.

💥 Why Killa Will Forever Be an Action Icon

Scott Adkins transformed a one-scene villain into a full-blown moment. From the meticulous character work to the daring physical choices, he proved that a great performance can turn an antagonist into a fan favorite. Even years after the film’s release, Killa is living rent-free in our heads. So whether you’re re-watching John Wick: Chapter 4 for the tenth time or just discovering it now in 2026, one thing is certain: Killa is that guy. And we need more.
