What does the term "run" refer to in the context of theatre?

The term "run" in the context of theatre primarily refers to the number of performances scheduled for a particular play or production. This encompasses the entire duration that the show is performed, from its opening night to the final performance. A play can have a short run, meaning it is performed for only a few days or weeks, or a long run, where it might be performed for several months or even years. This usage is common in theatre discussions as it gives an indication of how long the production will be available for audiences to see.

In contrast, the other choices address different aspects of theatrical production. The duration of rehearsals can vary significantly and does not define the term "run." The length of the play refers to how long the actual performance lasts, typically measured in minutes or hours, rather than the total number of performances. Lastly, an actor's performance period might relate to a specific role or engagement but does not encompass the overall meaning of the term "run" in theatrical terminology.
