Casting Call
1. In the performing arts, casting (or casting call) is a pre-production process for selecting a cast (a meaning of the word recorded since 1631 of actors, dancers, singers, models and other talent for a live or recorded performance.
The casting process somewhat involves a series of auditions before a casting panel, composed of individuals such as the producer, director and/or choreographer. In the early stages of the process, performers often may present prepared audition pieces such as monologues or songs. These audition pieces are usually video taped, attached with resumes, and head shots and then shared with producers, directors and studio representatives. Later stages may involve groups of actors attempting material from the work under consideration in various combinations; the Casting Director considers both the talent of the individual actors and the chemistry of their combination.
