Netflix has confirmed that A-list actor Park Seo Joon will pop up in the sophomore season of its gritty action-noir series Bloodhounds—a cameo that instantly set K-drama Twitter ablaze. “It is true that Park Seo Joon will be making a special appearance in Bloodhounds 2. However, we cannot provide further details at this time,” a Netflix source told Korean press on 10 July.
A reunion years in the making
Park’s cameo reunites him with director Kim Joo-hwan and lead actor Woo Do-hwan. The trio last worked together on the hit films Midnight Runners (2017) and The Divine Fury (2019); fans have long hoped they’d share the screen again. Industry watchers say Kim personally reached out to Park after completing the season-two script, which widens the story’s scope from Seoul’s loan-shark underworld to an international illegal boxing league.
What we know about Season 2

Bloodhounds season one followed rookie boxers Gun-woo (Woo Do-hwan) and Woo-jin (Lee Sang-yi) as they took down a ruthless money-lending syndicate. Season two, already deep into filming, pushes the pair into a globe-spanning fight circuit run by new antagonist Baek Jeong (Rain). Netflix has pencilled in a 2026 global release after post-production wraps early next year.
Park Seo Joon’s mystery role
All parties are tight-lipped on character details, but Korean outlets speculate Park could play:
-
A seasoned prize-fighter mentoring—or menacing—our leads.
-
A shadow investor bankrolling the underground league.
-
An Interpol liaison tracking the blood-soaked betting ring.
Given his track record in action (The Divine Fury, Itaewon Class) and slick charisma, any of the above would slot neatly into Bloodhounds’ bruising universe. Netflix’s secrecy suggests his screen time may be short but pivotal, much like his scene-stealing cameos in Record of Youth and Dream High 2.
Why the cameo matters
-
Brand power: Park’s name alone can spike global viewership; season one already cracked Netflix’s Top 10 in 83 countries.
-
Story synergy: His reunion with Kim Joo-hwan promises the same kinetic fight choreography and bromance chemistry that made Midnight Runners a cult classic.
-
Career momentum: Park is juggling the rom-com film Waiting for Gyeongdo (December 2025) and the dark thriller drama I Am a Sinner. A high-octane cameo keeps his action credentials fresh between long-form projects.
Fan reaction & social buzz
Within hours of the announcement, “#ParkSeoJoon” trended in South Korea, the Philippines, and Indonesia. Fan edits comparing Bloodhounds’ boxing sequences with Park’s MMA bouts in The Divine Fury racked up hundreds of thousands of views on TikTok. At the same time, Reddit’s r/KDRAMA megathread hit 2,000 comments debating his potential character arc.
The road ahead
Filming for Bloodhounds 2 continues through autumn, with a wrap party expected in November. Netflix will likely drop the first teaser early in 2026 once visual effects work on the international fight arenas is complete. Until then, viewers can revisit season one—or cue up Midnight Runners for a taste of the crackling Park-Woo-Do-hwan dynamic soon to be rekindled.
