An Actor-Director is a professional in the film and theater industry who takes on both acting and directing roles. This dual responsibility allows them to shape the performance of a production while also portraying a character. Notable examples of actor-directors include Clint Eastwood and Greta Gerwig, who have successfully balanced both roles in their careers. In this capacity, the actor-director must understand the artistic vision of the project and guide other actors while also delivering their own performance. This unique position can enhance the storytelling process, as they bring a deep understanding of character development and narrative pacing to both acting and directing.
