After 10 Years in TWICE, Jeongyeon Is Finally Acting and She’s Playing a Nurse Officer in a Haunted Military Hospital

TWICE’s lead vocalist makes her screen debut in New Recruit: The Movie, bringing K-pop star power to the big-screen expansion of ENA’s record-smashing military hit.

Ten years. That’s how long Jeongyeon has stood on stage as one of TWICE‘s lead vocalists through nine members, countless chart-toppers, and a decade of being one of K-pop’s most recognizable voices. Now, for the first time, she’s trading the mic for a script. And she’s doing it in one of the most unexpected places imaginable: a haunted military hospital.

Distributor KT Studio Genie confirmed on October 1 that Jeongyeon has been cast in New Recruit: The Movie A Ghost Lives in the Military Hospital (신병 더 무비: 군병원에 귀신이 산다), directed by Min Jin-ki. She’ll play a commissioned nurse officer named Yoo Jeong-yeon a role that doubles as her official acting debut.

A Franchise That Refuses to Fade

To understand why this casting matters, you have to understand what New Recruit (신병) has become. Born from a web animation by the YouTuber Jangbbijju, the franchise grew into an ENA drama series that found an improbable sweet spot mining the rigid, often absurd routines of South Korean mandatory military service for both sharp comedy and surprising warmth.

Rather than fading with age, the series has only gained momentum. New Recruit 4, which aired through late September 2026, shattered the franchise’s own records: its finale pulled a nationwide rating of 5.2%, peaking at 5.8% per minute the highest numbers across all four seasons. A fifth season is already in positive discussions. In an era of fragmented viewership, a cult military dramedy climbing to new heights in its fifth year is a genuine anomaly, and it speaks to how deeply the show’s blend of realism and heart resonates with Korean audiences who’ve lived that experience firsthand.

From the Barracks to the Big Screen With a Twist

The movie is more than a victory lap. Where the drama lived inside the barracks and the daily grind of unit life, New Recruit: The Movie relocates the universe to a military hospital and pivots sharply into horror. The premise: a group of soldiers, admitted and dreaming of a rare stretch of peaceful rest, instead find themselves trapped in a nightmare as they uncover the chilling secrets of a hospital they’d believed was paradise.

That genre swerve is a bold creative gamble. Transplanting a beloved comedy franchise into horror risks alienating the fans who came for the laughs but it also gives New Recruit room to grow beyond the formula that made it. Director Min Jin-ki, who has steered all four seasons to success and is the architect of the series’ record-breaking run, clearly has the fans’ trust to take that swing. If anyone can make soldiers-meet-ghosts work on the big screen, it’s the filmmaker who already proved the franchise’s staying power four times over.

The Core Cast Reunites and Expands

Crucially, this isn’t a reboot with new faces. The actors who built New Recruit into a phenomenon are all reporting for duty, including Kim Min-ho, Nam Tae-woo, and Kim Yo-han. The film also adds a notable new recruit of its own: Ryu Kyung-soo, a reliably magnetic character actor, joins the universe for the first time.

Dropping Jeongyeon into that ensemble is a savvy move. The returning cast guarantees continuity for the loyal fanbase, while her presence extends the film’s reach to TWICE’s enormous global following fans who may never have watched the ENA drama but will absolutely show up for Jeongyeon’s first acting role.

A Debut a Decade in the Making

For Jeongyeon personally, the timing carries weight. She’s spoken candidly in the past about health and personal challenges, stepping back from group activities at points to recover. Her return reportedly in a healthier, renewed state now comes paired with a creative reinvention. Choosing a grounded, dramatic role as a nurse officer, rather than a flashy idol-friendly cameo, signals genuine intent. This is an idol betting on herself as an actor.

It’s also part of a broader pattern. TWICE members have increasingly branched into solo music, variety, and acting as the group matures past its tenth anniversary, each carving out an individual identity beyond the collective. Jeongyeon’s screen debut is her entry into that next chapte and the fact that it comes through a franchise with proven box-office pull, rather than a risky vanity project, suggests she’s being set up to succeed.

Why This One’s Worth Watching

New Recruit: The Movie is slated to open in theaters this winter. It arrives carrying real expectations: a franchise at the peak of its popularity, a daring genre reinvention, a trusted director, a beloved returning cast, and a K-pop debut that could draw an entirely new audience into the fold.

Whether Jeongyeon’s first turn in front of the camera becomes a one-off experiment or the start of a second act, one thing is clear after ten years of hitting every note on stage, she’s finally ready to find out if she can do it on screen. This winter, in the eerie corridors of a military hospital, we’ll get our first real answer.
