Who manages the cast preparation during film production?

The 1st assistant director (1st AD) plays a crucial role in managing the cast preparation during film production. This position involves overseeing the day-to-day operations on set, which includes scheduling cast calls, ensuring that actors are prepared for their scenes, and coordinating with the director to maintain the flow of production. The 1st AD is responsible for communicating the director's vision to the cast and crew, making sure that the actors are ready and aware of their cues, and helping to maintain a productive atmosphere on set.

In addition to cast preparation, the 1st AD also manages the call sheet, which outlines the shooting schedule for the day, and makes sure that everyone is on the same page regarding timings and logistics. This structure is essential for keeping the production organized and on schedule, which is a fundamental aspect of film production. The other roles listed, while important in their own right, do not focus primarily on managing cast preparation.
