Honestly, it’s not easy to find such a well-made film in the Korean film industry these days, especially in the horror genre, right? But the recently released well-made horror film has been a hot topic every day, hasn’t it? It topped the box office immediately after its release and is causing a sensation, but this is not just a simple horror movie. The fact that it’s set in the actual ‘Salmokji‘ reservoir in Yesan, South Chungcheong Province, is already unusual. This reservoir is already known as a famous haunted spot among ghost story enthusiasts.
, which deals with bizarre incidents that occur when a road view filming team encounters a mysterious entity, is different from films that just haphazardly throw in clumsy jump scares. It delivers horror that truly captivates people with psychological pressure and atmosphere. So, shall we delve into why this movie is so hot, and what you should know to enjoy it even more?
Salmokji Movie: Not Just a Simple Ghost Story?

In fact, one of the biggest charms of the movie is that it is set in a real place. The Salmokji Reservoir in Yesan, South Chungcheong Province, is famous as a prime fishing spot among anglers and as a ‘never go there’ haunted spot among those who love ghost stories. Its notoriety has grown even more after being featured multiple times on programs like ‘Midnight Ghost Stories’.
The film builds its world by adding imagination to these real ghost stories, and it’s absolutely brilliant. The director himself reportedly got ideas by exploring Salmokji. Instead of just bringing a scary story, he perfectly transferred the gloomy and ambiguous atmosphere of the place itself onto the screen. Perhaps that’s why you can feel an eerie sensation throughout the movie, as if the boundary between reality and fantasy blurs.
- Although the title is taken from the actual place name ‘Salmokji’, it is said to be derived from a nearby place name and thus different from the meaning of ‘Salmok (殺木)’.
- The background of the reservoir, famous as both a fishing spot and a haunted spot, maximizes the horror of the film.
- It is based on ghost stories introduced through various broadcasts and YouTube channels, such as .
The Passionate Performances of the Actors Saved the Movie!

The incredible acting skills of the cast also play a significant role in why this movie is receiving so much attention. In particular, Kim Hye-yoon, who plays the protagonist PD Su-in, has successfully shed her ‘rom-com queen’ image and established herself as a ‘horror queen’ with this work. She expresses the complex emotions of a character with water trauma solely through her eyes and expressions, which was truly chilling. It made me realize why she’s known for her excellent acting.
Lee Jong-won also took on his first leading role in a commercial film as Gi-tae, Su-in’s ex-lover who helps uncover the reservoir’s mystery, and his portrayal of being afraid of horror yet trying to protect Su-in was very impressive. Adding to this, Kim Jun-han, Kim Young-seong, Oh Dong-min, Yoon Jae-chan, and Jang Da-ah all deliver performances that perfectly embody their characters, greatly enhancing the film’s immersion. Jang Da-ah, despite this being her film debut, showed quite stable acting.
The Director’s Direction, Making Horror ‘Seep In’

Despite being director Lee Sang-min’s feature film debut, his direction is extraordinary. He focused on creating horror through psychological pressure and atmosphere rather than cruel scenes or overt jump scares. He maximizes the enclosed and gloomy feeling of the reservoir to deliver horror that makes the audience imagine things themselves. Isn’t this truly the directing style of masters?
Especially when watched in special theaters like 4DX or ScreenX, the sense of horror is said to be doubled. They say water is sprayed when the water ghost appears, which sends shivers down my spine just thinking about it. At this point, it’s safe to say that he has presented a new standard for Korean horror films. The director said he wants to continue making horror films connected to reality, and I’m already looking forward to his next work.
- Director Lee Sang-min, based on his short film experience, showcased direction skilled in psychological depiction.
- His direction is characterized by focusing on the pressure created by the situation rather than cruel visual stimuli.
- During 4DX screenings, water is actually sprayed during the water ghost scene, allowing for a more realistic sense of horror.
Thus, is captivating audiences as a clever and profound horror film that goes beyond a simple ghost story. It’s no exaggeration to say that it’s writing a new history for Korean horror films in 2026. If you haven’t seen it yet, I highly recommend experiencing it this weekend. You probably won’t be able to sleep at night!
