What does "loading in" refer to in theater?

"Loading in" specifically refers to the process of bringing set pieces, costumes, and equipment into the theater before a production begins. This is a critical step in the production process, as it involves the coordination and logistics needed to move various elements of the show into the performance space, ensuring that everything is in place for the upcoming performances. During the loading in, the crew will unload trucks, set up the stage, and prepare all necessary materials to create the desired environment for the audience. This step is essential for ensuring that everything runs smoothly and that the production is ready for rehearsals and performances.

The other options, while related to theater production, do not accurately reflect the meaning of "loading in." Setting up the audience area, rehearsing individual scenes, or working with the full cast are separate processes that occur in the production timeline but do not define what "loading in" entails.
