To become a movie extra, one must usually be listed by a casting agency, such as Central Casting, a no-fee agency that supplies extras to the major movie studios in Hollywood. In recent years, only a very small proportion of applicants has succeeded in being listed. There are no specific training requirements for directors and producers, so they come from many different backgrounds. Talent, experience, and business acumen are very important determinants of success for directors and producers. Actors, writers, film editors, and business managers commonly enter these fields.
Producers often start in the industry working behind the scenes with successful directors.
Additionally, formal training in directing and producing is available at a number of colleges and universities. As the reputations of actors, directors, and producers grow, they are able to work on larger productions or in more prestigious theaters. Actors may also advance to lead or specialized roles. A few actors move into acting-related jobs, as drama coaches or directors of stage, television, radio, or motion picture productions. Some teach drama in colleges and universities.
