12 Multi-Casting System
Korea
Multi-casting is a defining feature of Korean musicals. Leading roles are often shared by two to six actors, each bringing a distinct interpretation. This allows audiences to choose performances based on preferred cast combinations, creating a personalized viewing experience. It also enables producers to combine idols, established stars, and crossover performers within a single production, broadening audience reach and sustaining ticket sales in a domestic, repeat-viewer market.
​
The system, however, comes with trade-offs. Popular leads may appear in only two or three performances a week while simultaneously committing to multiple productions. Illness or scheduling conflicts can ripple across several shows, and audiences may experience fatigue when familiar acting styles recur across different roles. While multi-casting increases flexibility on paper, it does not always guarantee availability in practice.
​
The persistence of multi-casting in Korea reflects structural necessity rather than artistic preference. Unlike Broadway or the West End, which are sustained by continuous tourist audiences, the Korean musical market relies heavily on a finite pool of domestic enthusiasts, many of whom attend the same production multiple times. Rotating casts allows productions to extend their lifespan, distribute audience demand, and mitigate burnout within a limited market.
​
Although the underlying reasons differ, the resulting structure closely resembles operatic casting systems. As in opera, audiences are encouraged to compare interpretations, follow preferred performers, and revisit the same work through different casts. In this sense, Korean multi-casting does not imitate opera by design, but arrives at a similar model through market constraint rather than repertory tradition.

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
Among Korean audiences, multi-casting is often understood as a system designed to protect performers’ vocal health. However, this explanation alone does not fully account for the prevalence of multi-casting in Korean musicals. On Broadway, principal performers commonly sustain eight performances per week, supported by formally established understudy and alternate systems. In this context, vocal demand or performance frequency alone does not necessarily require multi-casting.
​
Cases in which vocal protection functions as the primary rationale for multi-casting are more accurately found in opera. Operatic repertoire demands prolonged high tessitura and sustained vocal intensity, making the rotation of multiple singers a structural necessity even within relatively short performance runs. From this perspective, multi-casting in Korean musicals emerges from a different set of conditions, distinct from both Broadway’s understudy-centered model and opera’s singer-protective tradition.
​
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.
