Many successful actors continue to accept small roles, including commercials and product endorsements. Some actors employed by theater companies teach acting courses to the public. Directors interpret plays or scripts. In addition, they audition and select cast members, conduct rehearsals, and direct the work of the cast and crew. Directors use their knowledge of acting, voice, and movement to achieve the best possible performance and usually approve the scenery, costumes, choreography, and music.
Producers are entrepreneurs.
They select plays or scripts, arrange financing, and decide on the size and content of the production and its budget. They hire directors, principal members of the cast, and key production staff members, and they negotiate contracts with artistic personnel, often in accordance with collective bargaining agreements. Producers also coordinate the activities of writers, directors, managers, and other personnel. Working Conditions Acting demands patience and total commitment, because there are often long periods of unemployment between jobs. While under contract, actors are frequently required to work long hours and travel.
