I’ve always had a soft spot for spy movies that don’t bother with the tuxedos and martinis. The ones that drop you into a world where the rules are written in blood, not ink, and the only currency is survival. Yaksha: Ruthless Operations is one of those films—a gritty, kinetic thriller that trades glamour for grime, and charm for ruthlessness. It’s not trying to be James Bond; it’s trying to be something messier, something closer to the bone.
And for the most part, it succeeds.
The film follows Ji-hoon (Sul Kyung-gu), the eponymous Yaksha, a black-ops team leader stationed in Shenyang, China, where he’s carved out a reputation as a man who gets things done—no questions asked, no bodies left to identify. His latest mission, however, forces him to confront the one thing he’s spent his career avoiding: a past that refuses to stay buried. When a prosecutor from Seoul (Park Hae-soo) arrives to investigate a murder tied to Ji-hoon’s operations, the two men are thrust into a high-stakes game of cat and mouse, where trust is a liability and every ally could be a traitor.
What Yaksha gets right is its sense of place. Shenyang isn’t just a backdrop; it’s a character, a labyrinth of neon-lit streets, crumbling infrastructure, and whispered deals. The film’s cinematography leans into the city’s grittiness, using tight close-ups and handheld camerawork to create a sense of claustrophobia.
You can almost feel the damp in the air, the weight of the secrets pressing down on every frame. It’s a far cry from the sleek, sterile aesthetic of most spy thrillers, and that’s a good thing. The film’s world feels lived-in, dangerous, and utterly real.
The action sequences, too, are a standout. Na Hyun doesn’t rely on flashy CGI or over-the-top set pieces. Instead, the fights are brutal, close-quarters affairs—knives, fists, and improvised weapons doing the talking.
There’s a rawness to them that’s refreshing, a reminder that in this world, violence isn’t a spectacle; it’s a necessity. The choreography is sharp, but it’s the sound design that really sells it. The wet thwack of a blade sinking into flesh, the guttural grunts of men fighting for their lives—it’s visceral in the best way, the kind of thing that lingers long after the credits roll.

Buzz & Rumors
Public reportsInside the Ruthless World of Yaksha: Ruthless Operations
Netflix’s 2022 Korean spy thriller Yaksha: Ruthless Operations delivers high-octane action and a morally ambiguous lead, but the film’s behind-the-scenes story is just as intense as its on-screen missions. Directed by Na Hyun, the movie stars heavyweights Sul Kyung-gu and Park Hae-soo in a cat-and-mouse game set in the shadows of Shenyang, China. Here’s what we know about the making of this gritty blockbuster.
A Spy Thriller with Real Stakes
Yaksha follows Kang In (Sul Kyung-gu), a ruthless National Intelligence Service (NIS) operative leading a black ops team in China. His mission? Uncover a mole within his ranks while navigating the dangerous underworld of espionage. The film’s premise—rooted in the murky ethics of intelligence work—was reportedly inspired by real-world tensions between North and South Korea, though the script takes creative liberties 
.
Park Hae-soo, fresh off his global breakout in Squid Game, plays Ji Hoon, a prosecutor sent to investigate Kang In’s operations. Their dynamic—tense, distrustful, and laced with explosive confrontations—drives the film’s emotional core. The supporting cast, including Japanese actor Hiroyuki Ikeuchi and K-pop idol Jinyoung, adds international flair, reflecting the movie’s cross-border setting .
The Director’s Vision: Brutal Action, Moral Ambiguity

Na Hyun, known for his work on crime dramas, leaned into the film’s raw, unfiltered tone. Early trailers teased a level of violence and intensity rarely seen in Korean spy films, with fight choreography designed to feel visceral and unpolished. The director reportedly pushed the cast to embrace the physicality of their roles, leading to some on-set injuries—though details remain scarce .
One standout sequence, teased in the Netflix trailer, involves a high-speed chase through Shenyang’s neon-lit streets. The scene was shot on location, a rarity for Korean productions filming in China, and required meticulous coordination with local authorities. Rumors suggest the production faced delays due to bureaucratic hurdles, though neither Netflix nor the filmmakers have confirmed specifics .
Controversy and Mixed Reception
Despite its star power and slick action, Yaksha divided critics. Some praised its relentless pacing and Sul Kyung-gu’s chilling performance, while others criticized its convoluted plot and underdeveloped side characters. French review aggregator SensCritique gave it a lukewarm 5.6/10, citing a lack of narrative depth .

The film’s marketing also sparked debate. Early teasers emphasized its "ruthless" tagline, but some viewers felt the final product didn’t fully deliver on its promise of unflinching brutality. Netflix, however, leaned into the hype, releasing multiple trailers and international subtitled versions to maximize global appeal .
What’s Next for the Cast?
With Yaksha now a fixture on Netflix’s action-thriller roster, fans are speculating about potential sequels. Park Hae-soo’s rising star power (thanks to Squid Game and Narco-Saints) makes him a likely candidate for a return, though no official plans have been announced. Sul Kyung-gu, a veteran of Korean cinema, has remained tight-lipped about future projects, but his performance in Yaksha proves he’s still a force to be reckoned with .
As for Na Hyun, the director’s next move remains unconfirmed. If Yaksha’s success paves the way for more high-stakes espionage films, audiences can expect even grittier storytelling ahead.
