K-Musical Culture
12 Multi-Casting System
Korea
Multi-casting is a defining feature of Korean musicals. Protagonists are often played by several actors, each offering a distinct interpretation. This lets audiences choose performances based on preferred cast combinations, creating a personalized experience. It also allows producers to feature idols, established stars, and crossover actors, broadening fan bases and boosting ticket sales.
The system, however, has drawbacks. Popular leads may appear in only two or three shows a week while juggling multiple productions. Illness or scheduling conflicts can ripple across several shows, and audiences sometimes feel fatigue when familiar acting styles repeat from role to role.

Performer Well-Being
While multi-casting secures box office stability, it can strain performers. Lead actors frequently appear in two or three productions at once, sustaining ticket demand but risking vocal health and stamina.
Some push themselves rather than risk fewer casting opportunities, while others have had to carry entire runs alone when colleagues were unavailable—exposing how thin the safety margin can be. Ultimately, accepting overlapping roles is the actor’s choice, but the star-driven casting culture often rewards endurance over sustainability. Reports of vocal fatigue, disrupted rehearsals, and delayed recovery underscore how fragile the balance is between artistry, health, and commercial pressure.
Rules vs. Practice
Audition notices typically forbid actors from overlapping productions during rehearsals or runs, aiming to reduce conflicts and protect focus. In reality, exceptions are routine. Lead actors, and increasingly supporting cast, take on simultaneous commitments—even during rehearsal periods for new shows.
​
This growing reliance on multi-casting reflects the industry’s expansion and its dependence on ticket-selling performers. Yet it also raises questions of sustainability, artistic depth, and performer well-being as more actors split themselves across multiple productions at once.
Comparison with Broadway and the West End
Unlike Korea, Broadway and West End productions rarely employ multi-casting for leading roles. Most principals perform six to eight shows a week, with official understudies and standbys covering absences. This creates consistency for audiences but less flexibility in casting. Korea’s model, by contrast, maximizes variety and ticket sales through rotation, but places different kinds of pressure on both performers and productions.
Comparison with Opera
Multi-casting is also common in opera, though its function differs from musicals. Alternating singers in a role provides audiences with the chance to hear diverse interpretations and protects singers’ voices, since operatic performance is highly demanding. Unlike musicals in Korea, which may run three to six months, opera productions are usually limited to just a handful of performances. If a singer becomes ill, another cast member can swiftly cover, and even single-cast productions usually prepare a cover singer during rehearsals.
At the same time, opera companies benefit commercially from this practice. Featuring multiple world-renowned singers in a single run is also a ticket-selling strategy, drawing audiences who want to compare interpretations or follow specific stars. Thus, opera multi-casting balances artistic, practical, and commercial goals in ways both similar to and distinct from the Korean musical scene.
Limits of the Korean System
Opera demonstrates that multi-casting can work well when coverage is guaranteed, but Korean musicals often lack that safety net. Even with multiple actors cast in the same role, scheduling conflicts mean they are not always available on the same day or even the following performance.
When a show is canceled, audiences typically receive a 110% ticket refund. Yet for those who have already paid for travel, accommodation, or taken time off work, this compensation only adds to the frustration. This highlights the fragility of the Korean model: while multi-casting increases variety and star power, it does not always provide the reliability audiences expect.
