A talent agent, or booking agent, is a person who finds work for actors, authors, broadcast journalists, film directors, musicians, models, professional athletes, screenwriters, writers, dancers, and other professionals in various entertainment or sports businesses. In addition, an agent defends, supports and promotes the interest of their clients.
Having an agent is not required, but does help the artist get jobs (concerts, tours, movie scripts, appearances, signings, sport teams, etc.). In many cases, casting directors or other businesses go to talent agencies to find the artists for whom they are looking. The agent is paid a percentage of the star's earnings. Various regulations govern different types of agents. The legal jurisdiction in which the agent conducts business and artist's unions set the rules. There are also professional associations of talent agencies.
