Final answer:
Directors are responsible for guiding actors, integrating design and technical elements, and blocking the show during rehearsals.
Step-by-step explanation:
Once rehearsal begins, directors are responsible for several tasks. Firstly, they guide the actors in their process by answering questions about their characters and assisting them with any issues that may arise. During technical rehearsals, the director's attention shifts to the whole ensemble of the production, ensuring that all design and technical elements are integrated smoothly. Additionally, the director blocks the show, creates stage pictures, and takes care of transitions by coordinating the movement of actors on stage.
