What is a first assistant?

First Assistants, often referred to as First Assistant Directors (First ADs) in film and television production, are responsible for coordinating all production activities on set. They assist the director by managing the shooting schedule, ensuring that cast and crew are prepared, and facilitating communication between departments. Their role is essential in keeping the production running smoothly, safely, and on time. First Assistants also help enforce safety protocols and can be involved in overseeing rehearsals and blocking scenes. Overall, they play a key organizational and leadership role in any production.
