16+ Stellar Idol Musical Actors Who Tried Their Hands in Theater

Idols have spent anywhere from months to years honing their skills in singing, dancing, and acting—so it’s no surprise that they would be great in many other entertainment fields, including theater. Their amazing stage presence not only light up concert venues; they dazzle on musical stages as well!

Here are 16 (and more!) idols who have found equal success as musical actors:

Kyuhyun (Super Junior)

Kyuhyun debuted in 2006 as the maknae and one of the main vocalists of 2nd generation legend Super Junior. He is one of the best active idol vocalists, so it’s no surprise that his voice would also captivate musical fans.

He made his musical theater debut in 2010 with The Three Musketeers. He was next cast as Frank Abagnale, Jr. in the Korean production of Catch Me If You Can. In 2013, he reprised his roles in re-runs of both musicals. Kyuhyun took on roles in Moon Embracing the Sun, Singin’ in the Rain, The Days, Robin Hood, Werther, and Mozart! from 2014 to 2016, before taking a break to fulfill his mandatory military service.

Upon completing his military duty, Kyuhyun resumed his musical career with The Man Who Laughs in 2020. He was cast in the main role as Gwynplaine, alternating with EXO’s Suho. In the same year, he reprised his role in Werther.

In 2021, Kyuhyun starred in the musical Phantom. He recently capped his performances as Victor Frankenstein in Frankenstein, where he starred alongside VIXX’s Leo.

Ryeowook (Super Junior)

Just like his fellow SJ member, Ryeowook has been active both as an idol and as a musical actor. He made his musical theater debut in 2011’s Temptation of Wolves. The idol next took on the role of Troy Bolton in the Korean stage adaptation of High School Musical in 2013. Since then, Ryeowook has starred in several more productions—Goddess is Watching, Agatha, and The Curious Incident of the Dog in the Night-Time—before enlisting in the military in 2016.

Ryeowook jumped right back into his idol and musical actor career after being discharged from the military in 2018. He was cast in Flaming Sonata, Around Thirty, and Mary Shelley. His most recent musical is Fan Letter.

Leo (VIXX)

VIXX’s soft-spoken main vocalist, Leo, may look shy and reserved, but once the concert lights come on, he transforms into a powerhouse performer. The same happens whenever he’s on the musical stage.

Leo began his musical career in 2014 with the musical adaptation of the K-drama Full House. Since 2016, he has used his real name, Jung Taek Woon, when being credited in stage productions. Leo starred in five more musicals—Mata Hari, Monte Cristo, The Last Kiss, Elisabeth, and Marie Antoinette—all before his military enlistment in 2019.

In 2021, he took on the dual role of Henri Dupre and Frankenstein’s monster in the musical Frankenstein. The musical completed its run in early 2022.

Ken (VIXX)

VIXX’s “cute main vocal” Ken is one of the most active idol musical actors. He made his musical debut in the Korean adaptation of the musical Chess in 2015. Ken continued to show off his powerful vocals when he took on the lead roles in Cinderella, Boys Over Flowers The Musical, Hamlet, Titanic, Iron Mask, Jack the Ripper, Mefisto, Dracula, and Sherlock Holmes The Musical: The Lost Children.

His amazing talent and stage presence did not go unnoticed. In 2018, Ken won the Male Rookie of the Year award from the 12th Daegu International Musical Festival for his performance in the musical Hamlet.

Ken took a break from his idol and musical activities when he enlisted in the military in 2020. Upon his discharge, he was immediately cast as Arthur in Xcalibur. He recently wrapped up his performances in March 2022.

Suho (EXO)

EXO’s leader is more than just an idol; he’s also a movie and television actor, as well as a musical actor. Suho made his theater debut in the 2015 hologram musical School OZ. He then took on the role of Crown Prince Rudolf in 2017’s The Last Kiss. In 2018, Suho was cast as Gwynplaine in The Man Who Laughs; he reprised his role in the 2020 run.

Suho completed his mandatory military service as a public service worker in February 2022. Will we see more of musical actor Suho soon? We sure hope so!

Xiumin (EXO)

EXO’s oldest hyung, Xiumin, first got a taste of musical theater when he starred alongside Suho in School OZ. But he hit his stride in musicals when he starred in the army musicals Return: The Promise of That Day and Return in 2019 and 2020.

Post-military service, Xiumin was cast as Orpheus in the 2021 production of Hadestown.

But it seems that there really is no shortage of talent in EXO, as there are also other musical actors among the members! D.O was in the same army musical as Xiumin, Chen performed in the Korean adaptation of In the Heights, and Baekhyun starred in Singin’ in the Rain. Finally, Chanyeol led the cast in another army musical, Meissa’s Song!
