Final answer:
A single agent is a professional who represents artists, such as actors, helping to secure roles and negotiate contracts with casting directors, thereby advancing their clients' careers.
Step-by-step explanation:
A single agent refers to an individual, usually a professional with expertise in the entertainment industry, whose role is to represent artists, such as actors, in negotiating contracts and securing roles. Actors seek the help of an agent to advance their careers, and these agents work on their behalf to pitch them to casting directors for specific roles or projects. Alaine Alldaffer's reference to agents illustrates the vital role they play in the actor's career trajectory.
Agents use their network and industry know-how to help actors find opportunities that match their skills and career aspirations. They act as intermediaries between actors and casting directors, and they often have an in-depth understanding of the casting process. Their primary responsibility is to promote and advocate for their clients, negotiate terms and conditions of contracts, and ensure the actors' interests are well-represented in any deal.
