A "Casting Call" is an event where filmmakers, producers, or casting directors invite actors to audition for roles in a film, television show, or theater production. During this process, actors perform scenes or monologues to showcase their talent and suitability for specific characters. These calls can be open to the public or by invitation only, depending on the project. They often include details about the roles available, such as age, gender, and character traits. Successful auditions may lead to opportunities for actors to work with industry professionals and gain exposure in the entertainment world.
