Fans of Korean thrillers have something big to look forward to this fall. Netflix has officially announced the global release date for its highly anticipated action film Mantis. Netflix will premiere Mantis on September 26, 2025. The movie directly spins off from the 2023 hit Kill Boksoon, which became a breakout international success for the platform.
A Spin-Off With Bigger Stakes
Directed by Lee Tae-sung and co-written with Byun Sung-hyun. Mantis dives deeper into the dangerous world of assassins first introduced in Kill Boksoon. Han-ul, a top-tier contract killer, takes time off but gets forced back into action when the underworld order collapses. The teaser trailer, released ahead of the premiere, teases stylish action, fractured loyalties, and intense rivalries that will keep fans glued to the screen.
The Cast of Mantis
One of the biggest draws of Mantis is its star-studded lineup. Leading the film is Yim Si-wan as Han-ul, the titular “Mantis.” Known for his performances in both dramas and thrillers, Yim brings depth and charisma to the role of a deadly assassin navigating chaos.
Yim Si-wan stars alongside Park Gyu-young, who plays Jae-yi—Han-ul’s former training partner turned bitter rival. Their clash will drive much of the film’s emotional tension.
Adding further weight is Jo Woo-jin, cast as Dok-go, a legendary retired assassin who becomes entangled in Han-ul’s journey. With these three powerhouse actors at the core, Mantis blends action, suspense, and layered performances.
Why Mantis Matters
Kill Boksoon left fans asking for more from its complex assassin universe, and Mantis looks ready to deliver. Netflix is positioning this film not just as a spin-off, but as a standalone entry that expands the mythology. The blend of martial arts choreography, psychological drama, and stylish visuals makes it one of the most anticipated Korean releases of 2025.
With its September 26, 2025 release date, Mantis is set to dominate Netflix’s global charts. The official trailer has already ignited buzz, and with stars like Yim Si-wan, Park Gyu-young, and Jo Woo-jin at the center. The film promises a gripping ride for fans of action and K-thrillers alike.
