What is typically found in a prompt book?

A prompt book is an essential tool in theatrical production, serving as the central resource for managing all aspects of a performance from beginning to end. The correct answer highlights that a prompt book contains all technical cues and actor movements. This includes detailed information about the timing of lights, sounds, and scene changes, as well as blocking notes that indicate where actors should be positioned during different parts of the play.

Having this information consolidated in one location ensures that the production can run smoothly, allowing the stage manager and crew to coordinate their efforts effectively. By documenting everything related to the performance's execution, the prompt book becomes a vital reference point during rehearsals and performances, allowing for consistency and precision in the staging of the production.

Other elements mentioned, such as costume designs, cast biographies, and rehearsal schedules, are valuable in their own right but do not serve the same practical function in the ongoing operations of a performance as the technical cues and actor movements do. These other details might be found in different documents but are not the primary focus of the prompt book.
