A new Korean horror film, The Cursed (귀시, “Gwisi”), has quietly become one of the fall’s buzziest cross-over moments—pairing veteran actors with four beloved idols: MAMAMOO’s Solar, STAYC’s Sumin, Lovelyz’s Jisoo, and WJSN’s Eunseo. Directed by Hong Won-ki and distributed by BY4M Studio, the movie opened in Korea on September 17, 2025.

What the film is about

The Cursed spins a folkloric nightmare around a hidden “ghost market”—a place that appears when a “fox window” opens. People trade with spirits for things they desperately crave (money, beauty, grades, popularity)… and pay an unbearable price. It’s a sharp hook that blends urban legend with social critique.

Why K-pop fans are paying attention

This release marks big-screen debuts for Solar and Sumin, while Jisoo and Eunseo continue expanding into acting—turning the film into a genuine idol-actor ensemble. K-culture outlets highlighted Solar and Sumin’s first movie roles and framed the project as a must-see for fans curious about their acting range.

The cast & who they play

Alongside leads Moon Chae-won and Yoo Jae-myung, here’s how the idol quartet fits into the story world:

• Solar as Mi-yeon — a writer chasing her dream in a rural village, pulled toward the ghost market’s temptations.
• STAYC’s Sumin (Bae Su-min) as Soo-yeon — a student consumed by grades and entrance-exam pressure.
• Lovelyz’s Jisoo (Seo Ji-soo) as Eun-seo — a woman obsessed with appearance who enters a dangerous bargain.
• WJSN’s Eunseo as Eun-jin (international student chasing influencer clout). Eunseo promoted the film at the Seoul press screening, signaling a confident leap to film acting.

(Full principal cast also includes Seo Young-hee and Won Hyun-joon, broadening the movie’s horror credibility.)

From press screening to premiere buzz

Seoul media days showcased Sumin and Eunseo on the press line, feeding early curiosity among both filmgoers and fandoms. Coverage from SBS Star documented their appearances and the film’s positioning ahead of release. Meanwhile, trailers and clips circulated widely online, amplifying the “idol-actor” angle.

A folklore horror with modern teeth

The gwisi concept hits a nerve in contemporary Korea: academic pressure, beauty standards, and social-media validation are literalized into supernatural transactions. Critics and columnists flagged how the movie taps “chills” to comment on heat-of-the-moment desires—timely material for a September rollout.

Quick timeline

• Sept 9, 2025 — Seoul press screening (CGV Yongsan I’Park Mall).
• Sept 17, 2025 — Nationwide Korean release; official trailer push continues across film channels and K-pop communities.

Why this matters for the idols

• Career expansion: Solar and Sumin’s debuts broaden their public personas beyond music, a strategic move many third- and fourth-gen idols are making.
• Acting credibility: Media spotlights on Eunseo and Jisoo underline an ongoing transition from “idol who acts” to “actor who also idols.”
• Fan crossover: Horror’s mainstream appeal plus idol star-power = new audience inflows for both the film and the groups.
