What is the purpose of an actor's audition?

The purpose of an actor's audition is primarily to evaluate performers for roles. During an audition, directors and casting agents assess an actor's ability to interpret a character and their overall fit for a specific role in a film, theater production, or television series. This evaluation includes not only the actor's performance skills, such as delivery, emotion, and presence, but also their ability to connect with the material and convey the character's essence.

This process is integral to casting decisions, as it allows those in charge of the production to see firsthand how the actors embody the characters and interact with the script. The audition may involve reading lines from the script, performing a monologue, or even participating in group scenes to observe chemistry with other actors.

The other options, while relevant to different aspects of the film production process, do not capture the primary function of an audition. Discussing script changes pertains to the development stage of a project, training actors on set relates to their ongoing education and preparation during filming, and finalizing contracts is a logistical step that occurs after casting decisions have been made. Thus, evaluating performers for roles stands out as the central aim of an actor's audition.
