If you’ve been eagerly awaiting Nam Joo-hyuk’s return to the screen, the wait is officially over now that The East Palace is here, and it was worth every single day. Marking his first K-drama role since completing his mandatory military service, The East Palace showcases an actor who has returned sharper, physically imposing, and fully locked in. In fact, if we didn’t already have a cast for the live-action version of Solo Leveling, I would’ve loved to throw Nam Joo-hyuk’s name into the hat for consideration!

Directed by Choi Jung-kyu (The Devil Judge) and penned by the masterminds behind The Guest and Bulgasal, The East Palace is a dark fantasy period thriller delivers on every level: non-stop action, spine-chilling occult lore, and an unforgettable twist that turns the entire story on its head.
First of all… Nam Joo-hyuk is Back (and better than ever!).
Nam Joo-hyuk stars as Gu-cheon, a rough-around-the-edges, sarcastic spirit slayer with a unique trait: he can cross directly into the netherworld, known as the Realm of Gwi.
Having last seen him as the covert vigilante before his enlistment, seeing Nam Joo-hyuk wield a sword in Joseon-era robes and long hair feels like an absolute level-up. His military service clearly added a grounded, commanding physical presence to his performance. The East Palace’s Gu-cheon isn’t your typical noble hero. He’s exhausted, cynical, and just trying to survive the king’s demands, making his hero moments hit that much harder.
There’s intense action and a rich introduction to Korean spirits.
The East Palace’s visual direction and world-building shine when exploring the realm of spirits (gwi). The series crafts a deeply atmospheric, eerie atmosphere rooted in Korean folklore, populating the cursed palace with everything from lingering, remorseful spirits (gwi-mae) to vengeful malicious entities (ak-gwi).
The contrast between the bright, politically tense palace grounds and the dark, haunting spectral realm creates a constant sense of dread. Pair that with pulse-pounding, martial-arts-style sword fights against terrifying creatures, and you get a show that feels equal parts historical epic and dark fantasy horror.

The dynamic between Gu-cheon and Saeng-gang (Roh Yoon-seo), a sharp, quiet court lady who can hear the dead, serves as the emotional anchor of the series. Their forced alliance gradually turns into a fiery, sibling-like bond (this might just be me though… apparently, some people saw their relationship as a romantic thing?) as they realize the ghosts aren’t the only monsters lurking in the East Palace.
The Ultimate Reveal: SPOILERS AHEAD!!!
While the initial premise sets up a mysterious 30-year-old “pond spirit” curse targeting the royal bloodline, the narrative elevates in its second half, and much of that impact comes down to the phenomenal, game-changing reveal of Kwak Dong-yeon.
Appearing as the supposedly deceased Crown Prince, Kwak Dong-yeon turns in an absolute tour-de-force. The realization that the palace isn’t just being hunted by an ancient curse, but that the Crown Prince himself has returned as a monstrous ak-gwi driven by pure resentment and ambition, completely recontextualizes the mystery. Kwak Dong-yeon perfectly plays the unhinged, tragic malice of the spirit with magnetic intensity, elevating the final showdown into an emotional, high-stakes battle between human greed and spectral retribution – a great role to leave us with before his upcoming military enlistment.
Without a doubt, The East Palace is a triumphant comeback for Nam Joo-hyuk and a must-watch for fans of dark fantasy, Joseon political intrigue, and supernatural action. It balances terrifying folklore with incredible set pieces and stellar performances across the board.
If you loved Kingdom or The Guest, put this straight to the top of your watchlist.
