Netflix's All Of Us Are Dead boasts a massive cast of characters across its initial 12 episode run. First released on January 28, 2022, director Lee Jae-Kyoo's All Of Us Are Dead blends a coming-of-age drama in a South Korean school with a brutal apocalyptic zombie horror. The initial critical response has been overwhelmingly positive for the Netflix series, receiving particular praise for its compelling cast performances in the weeks following its release.
All Of Us Are Dead centers on Hyosan High School, where students of class 2-5 are suddenly thrown into a life or death situation as their peers begin to turn into zombies. With no food or water, and the internet and landlines cut off during the ensuing undead melee, the surviving students are forced to use everyday objects found in their school to fend off the zombies attempting to turn each of them into a horde member. The result is a highly gripping Korean drama that brings the Hyosan student's will to survive at all costs into sharp relief as All Of Us Are Dead season 1 wears on.
As implied by its zombie apocalypse premise, All Of Us Are Dead contains a slew of characters destined for death at the beginning of the season. The series is certainly not afraid to kill off new faces and established characters alike across its first season, which plays into its absolutely mammoth roll call of respected South Korean actors. Here's a complete cast and character guide to Netflix's All Of Us Are Dead, as well as where you know each main actor from.
Park Ji-hoo as Nam On-jo
Cheong-san's next-door neighbor and one of the more popular members of class 2-5, Nam On-jo is as close as All Of Us Are Dead gets to having a primary protagonist across its harrowing first 12 episodes. Much of Netflix's All Of Us Are Dead centers on On-jo's survival tactics alongside her classmates while simultaneously showing On-jo's father's attempts to save his beloved daughter. Nam On-jo is played by new South Korean acting sensation Park Ji-hoo, who is best known to date for her performance in the critically acclaimed 2018 film House of Hummingbird.
Yoon Chan-young as Lee Cheong-san
Cheong-san's relationship with his neighbor and classmate On-jo is one of the most compelling aspects of All Of Us Are Dead, with the pair routinely battling the zombie hordes together both inside and out of Hyosan High School. Early audience reactions to the Netflix drama suggest Cheong-san is one of the most popular characters in Netflix's K-Drama, which is owed in no small part to his immensely affable nature even in the face of death. Lee Cheong-san is played by Yoon Chan-young, who has won at least three drama awards in his native South Korea since 2013 as a highly respected child actor.
Park Solomon as Lee Su-hyeok
If Cheong-san represents the softer side of Hysosan High, then Su-hyeok is the mettle that keeps his classmates battling against All Of Us Are Dead's almost insurmountable zombie odds. A former bully turned reformed student, Su-hyeok is an adept fighter that comes in very handy as All Of Us Are Dead gets more bloody. Lee Su-hyeok is played by breakout star Park Solomon, who will star in Disney+'s upcoming movie Third Person Revenge following his Netflix debut in All Of Us Are Dead in early 2022.
Cho Yi-hyun as Choi Nam-ra
The clever-yet-cold character is a mainstay in K-Dramas, with Choi Nam-ra filling this role perfectly for All Of Us Are Dead. An incredibly studious and talented individual, Nam-ra's academic skill is offset by her cold indifference to her other classmates, even as many are being eaten and assimilated into the series' zombie horde. Nam-ra is played by Cho Yi-hyun, who is best known for starring in the ongoing Korean television series Hospital Playlist.
Ha Seung-ri as Jang Ha-ri
An older, final-year student of Hyosan High, Jang Ha-ri hopes to use her exceptional archery skills to gain a scholarship to a prominent sports university. Predictably, however, Ha-ri ends up using her considerable bowmanship to instead fend off waves of undead attackers alongside several other archery students. Jang Ha-ri is played by Ha Seung-ri, who boasts an impressive list of credits in her native South Korea dating back to 1999.
Yoo In-soo as Yoon Gwi-nam
No character is more reviled in All Of Us Are Dead than Yoo In-soo's Gwi-nam, a vicious bully that mercilessly torments other Hyosan High students. Although initially not the bully circle's ringleader, Gwi-nam quickly becomes the show's primary antagonist (outside of the undead) as he reveals the depraved lengths he will go to to save his own skin. Gwi-nam actor Yoo In-Soo began his acting career in 2017, starring in a series of Korean television dramas alongside a supporting appearance in Netflix's Korean drama Forgotten.
Lee Kyu-hyung as Song Jae-ik
A detective of Hyosan Police Station, Song Jae-ik's skepticism quickly turns to despair as he and his department are forced to contend with the virus outbreak. Song Jae-ik is played by legendary South Korean actor Lee Kyu-hyung, who first shot to fame with his portrayal of Yoo Han-yang in tvN's television series Prison Playbook. Kyu-hyung is celebrated in South Korea for his ability to portray a wide range of characters and tackle differing mediums and projects, such as musicals and web series, with consummate ease.
Jeon Bae-soo as Nam So-ju
While heroism is certainly not in short supply across All Of Us Are Dead season 1's runtime, On-jo's father Nam So-ju stands head and shoulders above many of the series' other characters. The captain of the Hyosan Fire Station rescue team 1, So-ju's fight to rescue his daughter and her peers is one of the defining character arcs of All Of Us Are Dead. So-ju is played by Jeon Bae-soo, who is best known to Western audiences for his harrowing turn in 2016's Korean horror movie The Wailing.
