The length of a run varies depending on the success and popularity of the production. Some shows may only have a limited engagement of a few weeks or months, while others can run for years. The longest-running Broadway show, for example, is "The Phantom of the Opera," which has been running continuously since 1988.
During a theatrical run, the show is typically performed multiple times per week, with occasional breaks or "dark days." The performance schedule may vary based on the venue and the availability of the cast and crew.
The end of a theatrical run can be due to various reasons, such as declining ticket sales, scheduling conflicts, or the desire to move the production to another venue or city. When a show closes, it may be revived at a later date or adapted for film, television, or streaming.
